Nissan LEAF Owner Reviews the i3 After 3-Day Extended Test Drive

I have always maintained that a good number of i3 buyers will be Chevy Volt and Nissan LEAF owners that have just finished up the three year lease on their vehicle. Phil Tipper is an EV "early adopter" and leased a Nissan LEAF. His lease will expire next spring so he's trying to decide which plug in vehicle he'll get next. The i3 is on his list of possibilities and when BMW recently offered the i3 extended test drive Phil  jumped on the opportunity to get to know the car a little more. I love this extended test drive offering from BMW. I think it's a great way to give prospective customers a chance to absorb what the i3 is all about. Phil is already an experienced electric car driver so he could focus more on the specific features of the i3, but many others who have never experienced electric drive will find the extended time they have with an i3 intoxicating. Having more than a few minutes during a quick test drive at a dealership will absolutely help convince people that may have been on the fence. It's simple, the more you drive electric the more you like it. That extra time behind the wheel may be all they need to make the decision to go electric for the first time. Phil wrote of his experience and thoughts on his time with the i3 and posted it to his blog. I thought is was interesting to hear what a Nissan LEAF driver thought of the i3 so I asked him if I could post it here and he obliged. Below is the post from Phil's personal blog:

As regular readers of my blog know, I'm actively researching the next electric car to replace our 2013 Nissan LEAF SL when its two year lease expires next June, and that the BMW i3 is on the top of my list of contenders.

I like the BMW because of its light weight for an EV (because of the carbon fiber structure of its "life module"), giving it the potential for good energy efficiency and promising good handling around corners, because it has a relatively powerful and torquey motor making it quick off the line, because BMW has tuned in tight steering and minimal body roll, because it is a rear wheel drive design (for classic sports car handling), because I like BMWs and I like the personal service that a premium brand provides, and because I can get a model with a range extender that offers a total of about 150 miles of range, with more range available with a fill-up of a tiny bit of gasoline. I like the idea that a range extender will let us take trips as far as Santa Barbara and San Diego without worrying as much about the reliability of public charging and the time recharging would take.

I'm also fascinated by the concept that having a range extender as a cushion will actually let us, paradoxically, drive more electric miles because we'll be more likely to take the EV than to fall back on the Prius, and because we'll be comfortable dipping deep into the battery's charge because the range extender will be there as a cushion and we won't risk needing a charge to get home.

On brief test drives of the i3, I had been able to briefly sample the car's quick acceleration and tight steering, but I'd had trouble getting used to the strong regeneration when the accelerator pedal is released, and I had even felt a bit of vertigo, especially as a passenger when the car was driven vigorously. So I had some concerns to resolve. On Facebook and in person, drivers of the i3 had told me that these concerns would resolve themselves quickly after I had gotten more used to driving the car. A longer test drive was needed.

To my delight, some BMW dealers recently began offering three-day test drives of the i3. This was exactly what I wanted. I found a dealer within 25 miles of my home that was offering the long test drives, Shelly BMW in Buena Park, California, and I found their internet team responsive and easy to work with. I thank them and applaud their willingness to take on the bother and expense of offering this program. To me, the BMW i3 is a car that benefits from a longer test drive so that the customer can learn its unusual.driving dynamics. In fact, I think that brief test drives around the block can be misleading, mostly because of the strong regeneration. I picked up a base model "Mega" i3 with the range extender engine and the optional 20 inch wheels and tires last Thursday morning.
Here are some of the comments about my experiences that I posted on the BMW i3 Facebook group.

Random impressions from first 24 hours, 150 miles:
Regen braking:

It's pretty much a non-issue and I beg to retract all of my earlier doubtful and even downright negative comments about it. It is different, but it is manageable and you adjust fairly quickly. I would still like to have the regen strength adjustable for a more relaxed driving experience in certain situations. At low speeds with this car, you WILL brake significantly if you need to lift your foot to readjust its position on the accelerator, and it would be very nice to be able to reduce the regen power if you just want to relax and coast with your foot off the pedal for a few seconds. Also, as many have said, the regen strength is lower at high speeds, so you don't go into full-on braking at freeway speeds if you lift off. My wife's first test drive comes in a day or so, and I expect her to have issues learning to drive the car smoothly, and I also expect uncontrollable giggling at some point during her test drive (from her, not from me). But I was able to drive her on a day trip today without her feeling too jerked about. And that was in both Comfort and EcoPro modes.

Ride and handling:

The car does bounce around a bit more than I like on uneven pavement in situations when I want a smooth ride, especially when I have a passenger. When I'm out for sporty driving by myself, the ride is tight and just fine for me. I put a lot of this down to the short wheelbase that allows the car to bob over bumps, and the 20 inch wheels with low profile tires. I had mentioned getting just a touch motion sick on short test drives before, but I have to say that I really haven't felt that in my first full day of driving the car. I imagine that having a chance for my inner ear and brain to get used to the car has something to do with that. I'll just say that the car is less relaxing to cruise in than my Leaf is because the steering is very responsive to any turning input and I find that I have to pay more attention to where the car is in the lane than I do with the Leaf. Some would say that's the price you pay for responsive steering. Fair enough.

Sporty driving:

Oh hell yes! You owners know this, but I think that the best kept public secret about the i3 is that there is a little sports car demon hiding inside this little thing. When I'm driving alone on a twisty, hilly road, it feels as good as any sports car I've driven (remember that I'm in the Mazda, Nissan, 3-Series class, not the Ferrari, Porsche class). The skinny tires grip on curves like the devil and the torque of the motor just goes on and on. Very, very grin-inducing, and very BMW. For me, this is the one and only reason for ME to get this car. Frankly, a fully optioned Leaf SL or a Mercedes B Class EV would do as good or better job for family cruising duty. They are more spacious and more relaxing to cruise around in. But in my experience, the i3 is more fun to fling around than a Tesla Model S because of its small size, light weight and tight handling. And I've driven a Model S on some of the same twisty roads. Given that I'm limited on parking space and we can't really have more than two cars, my EV has to be my fun car as well as being practical. Since the FUN potential of the i3 is so high, I can probably live with the practical downsides of the car.

Performance on Rex:

I haven't had much time driving the car in REx mode, but I purposely ran the battery down so that the car would go into Rex. There is a slight, almost unnoticeable vibration in the cabin, and you can hear the two cylinder motor chugging a little back there with the windows up. I drove the car fast up a pretty steep hill with the REx running and there was no reduction in power that I could detect. I must say that I do like having the REx there as a cushion. I've been driving EVs for over three years and I know how to handle range issues, but it was very nice to see a 40 mile cushion on the dashboard as we finished our 70 mile trip today (Note: The gas tank was less than 3/4 full).

Driving efficiency:

If the mi/kWh onboard readouts are to be believed, I'm getting no better efficiency in the i3 than I do with similar driving in my 2013 Leaf SL. I expected something like 20% better efficiency in the i3, but as near as I can tell, Nope! (Note: see my revised comment on efficiency near the end of the article.) You might say that I must be pushing the i3 harder, but after a day of cruising with my spouse aboard, I got around 4.2 mi/kWh, which is what I'd expect from my (heavier) Leaf in the same kind or driving. This was a mix of suburban and freeway driving, in a mix of EcoPro and Comfort mode. Go figure.

Random minor observations:
I like having frameless windows on the front doors. Getting in and out of the car is a pleasure when I don't have to contort to get around the upper door frame.

I like the placement of the 12v power plug for a phone charger. My phone sits down there in that well with the charger plug and I don't have wires everywhere.

The door pockets are spacious and handy for carrying all kinds of small items.

Installing kiddie seats in the back seats was a bit challenging. We have two grandkids, a four year-old and an infant. I had to remove the rear seat headrest so that the bigger kid seat would fit properly down into place. The base for the infant seat takes up a surprisingly large amount of space front-to-rear, so when we put in the actual carrier cradle into the base, the front seat will have to be moved forward a lot. Since I'm long-legged and tallish, we'll have to put the infant base behind the passenger and have her move her seat forward, and we'll have the bigger kiddo sit behind me, the driver, and she and I will have to negotiate over leg room.

Finally (after first 24 hours): No electronic or mechanical gremlins, errors, CELs, nothing. Very reassuring.

And here is my summary of my experience after the end of the three day test drive:

I'll summarize by saying that I liked the car very much, and that most of my concerns were eliminated after a few days driving it.

Positives:

+ The strong regen is a non-issue. It took a long test drive like this to convince me, but I no longer see this as a problem. Even my wife found it manageable. (BUT I do have to mention that she did have a second of unintended acceleration when she wanted to use the brake and forgot that her foot was still on the e-pedal. This was after only ten minutes driving the car for the first time, and we're sure that with more familiarity, this wouldn't be a problem.)

+ The quick acceleration and tight handling were really rewarding and these would be the biggest reasons that I'd choose an i3 over any of the competitive cars. This is really a little sports car disguised as an economical city car, and it's the true standout, as far as I'm concerned, for sportiest small four-door EV. (I know that the Spark is pretty quick, but it's really a tiny little thing and wouldn't work for us as a family hauler.)

+ Material and build quality were very good, even in the base Mega model. I happen to find the interior materials interesting and even the compressed Kenaf panels are fine with me.

+ I liked the maneuverability and tight turning circle.

+ I happen to like the car's unusual styling.

+ We were able to install kiddie seats for our two grandkids and reassure ourselves that the car would work for kid transport duty. This included one rear-facing infant seat and one front-facing kid seat. Space wasn't plentiful. The infant seat base takes up a lot of horizontal (front-rear) space, so it limits how far back a front passenger can move their seat. So we put the infant seat base behind the front passenger so that as the driver, I can get my needed leg space.

Features that I found only so-so:

* Having no keyless entry on the base car is cheesy, especially since the car has keyless-go.

* No option for power seats. That really should be an option for those who want it, with full disclosure that it adds weight and might harm range.

* I still find the seating position too high, and I kept wanting to lower the seat below the lowest setting. Ditto the steering wheel. It feels too high even at its lowest, and the high steering wheel position gives me a kink in my right upper shoulder.

* Loud and uncomfortable wind buffeting with the windows down above about 55 mph. I like to drive with the windows down, and without rear windows to open (or a sunroof) the "air hammer" that happens with the windows down is severe. I found that raising both windows to within about 4 inches of closed helps a lot.

* There was an annoying "reciprocating" thrum that I heard/felt at moderate to low speeds. I was never sure whether it was tire noise or drivetrain noise, or both, but it wasn't a typical EV driveline low howl that changes pitch as you slow to a stop. It was more of a cyclical thrum that got slower in its cycle as I slowed down. Is this typical for the i3, is it unusual, or could it have been specific to the 20 inch tires? (Update: Tom Moloughney, our i3 online guru, told me that he had confirmed this sound in his own i3 to be coming from the 20 inch tires.)

* The short wheelbase (five inches shorter than a LEAF's) makes the car rock and bob over road imperfections. It's tolerable but it sure isn't a serene riding car. For most of my personal driving, it's no problem at all, but for times when I want to treat my passengers to a smooth ride, it's intrusive.

* I won't get into complaints about the crippled USA REx implementation, but the EV range that I got with the car was an unimpressive 72-ish miles. That's fine for most of my driving, but I'm used to getting about 85 miles with my Leaf, so this felt a bit limited. I do like having the cushion of the REx, though, and I think it would let me drive more EV miles, because I'd choose to take the i3 more often when planned trip lengths are a bit long, and a total range of about 150 miles with the range extender is very attractive after driving a Leaf for three years. It will make the difference between being able to use the car fully and not being able to in the spread-out LA metro area.

* Energy economy was poorer than in my Leaf on the freeway, but better than the Leaf on suburban streets, including with spirited driving. I find this rather disappointing because if I get an i3 REx, I'd like to do more regional driving trips with it, and I was hoping for better freeway economy. OTOH, with the good economy at lower speeds, I can drive it around like a hooligan without any misgivings (free energy from our home's solar roof).

- The "coach" doors. Awkward to move kiddie seats in and out of the back seats unless you have plenty of space on the side of the car. We had to back the i3 out of the garage into the driveway to have enough space to swap the kiddie seats in and out. The maneuver also required removing one rear head rest because it interfered with the upper part of the forward-facing child seat, and this requires partially folding that rear seat forward to be able to remove the head rest. We found that it was also necessary to slide the front seats forward and flip the back rests forward so that we had enough room to get to the child seat restraints and belts.

We wind up needing to swap out the child seats a couple times a week because we have two cars and only one pair of child seats. So this will become a frequent exercise. Not a huge deal, but if it's raining (if it ever does around here again), I'd be either doing this drill in the rain in the driveway, or back the Prius out in the rain to be able to get the i3 doors fully open and move the kid seats in and out. First world problems, to be sure.

- The placement of the charge access door on the right rear fender. I was lucky that I chose a 25 foot cable when I bought my Aerovironment L2 EVSE. Since I mounted the EVSE near the left front fender of a headed-in car, my choices with the i3 are to back the car into the garage or to wrap the cord around the car to get the plug to the i3 charge port. The latter choice was the more appealing one to me, and it worked fine, aided by the i3's short overall length.

* And of course, I find the car's price and value for money proposition disappointing. I'm going to want a good sized discount AND a boost to the residual percentage to feel okay about the lease pricing. We'll see how things are next Spring, when I'm in the market. But BMW really needs to kick in the whole $7,500 Fed rebate, or price the car to make up for the difference. OCF (Owner's Choice with Flex - a purchase program with a guaranteed buy-back at the end of the term) programs are less attractive in California because you're charged sales tax on the car's full cost, even though you're only using it for a portion of its life. Leasing would be more attractive to me, but not at BMW's current pricing, rebate amount and residuals.

Lastly, the only issue or problem I had in three days and 265 miles was a problem with " low cost charging". Even though I had set the car in that mode, it insisted on charging immediately. This was with Level 2 charging with about 15% SOC remaining.

And by the way, my existing Aerovironment Level 2 home EVSE with Nissan badging worked great with the i3.

Born Electric Guest Blogger: Meet Fred From California

My name is Fred and I was born electric on July 30, 2014. 

Today I have just a little over 1,000 miles on my i3 REx—over 1,000 happy miles I should add. I live in Huntington Beach, California and use my i3 regularly for running local errands, for meetings of 80 to 120 miles across the Los Angeles basin, and for pure pleasure. Indeed, it is now the only car I own. I sold my Lexus LS460L and my Lexus SC430 for the i3, and while both are great cars, the i3 meets my needs so well that I have no regrets about giving up either of them.
  

I never intended to own an electric vehicle and paid little attention to them believing that they were in general impractical. I was raised on the internal combustion engine and had no intention of doing anything other than sticking with what I knew and what worked for me. Adding to my mind set were two facts:  first, America is awash in fossil fuels with the potential of freeing us from the importation of foreign oil; second, cars that once swigged gasoline are now increasingly fuel efficient.  So, why change?

Then one sunny Sunday morning my son, who traded in his Hummer for a big Infiniti SUV, came knocking on my door, roused me from bed, and said, “come with me,” informing me that we needed to be somewhere in a hurry. Before I could find out where we had to be, we were racing down Pacific Coast Highway to what I discovered was the BMW dealer in Newport Beach. My son wouldn’t tell me where we were going or why we were rushing to be somewhere, keeping this news from me until we arrived. As we pulled into Sterling BMW, my son informed me that I was going to do a test drive—a drive so I learned that he took the day prior.   

 

Smelling the roses

I had trouble believing that this was what all the fuss was about. My son has owned big vehicles for many years. He is a diver, and carts around lots of dive equipment. Also, we used his vehicles for towing our boats. Why in the world was he interested in this little car?  Besides never giving a moment’s thought to an electric vehicle, I never considered a small car. Except for the BMW 320i that I owned in the 1980s and my little Lexus sports car which I used on weekends, my driving experience consisted mostly of large cars--heavy metal objects that surrounded me with lots of steel and horse power. I assumed that I would be safer in an accident in a large car than in a small one. Once behind the wheel of the i3, my fear disappeared.  It is not true that in all things, small is beautiful, but in the case of the i3, it truly is.

The test drive was badly organized and although my son had signed us up for a specific time, we sat around for what seemed to be forever until we got our test car. Wanting my breakfast, I almost left. Further, when I tried to engage officials in charge of the test drive with questions about the vehicle, they seemed to know as little as I did. We were not off to a good start.
 

Once behind the wheel, everything changed. I immediately liked the clean lines and the airiness of the cabin. I especially liked the elevation of the seats with a firmness that secured my poor body against the discomforts of my arthritis. I abhor soft seats into which you sink, seats that require lowering yourself into position and then hoisting yourself out. I also liked the easy adjustment of the seats. While the seats in my Lexus vehicles are powered electrically, moving me like a belly dancer into every conceivable position, I  never got the setting I wanted. By comparison, once into the i3, I knew I found a home.

The clincher was the drive itself. As we pressed the button to start the “ignition”, I listened for the rev of the motor only to hear quiet, blessed quiet. I thought to myself, this is too good to be true. My son took the wheel first. He likes to drive fast and once onto the road way, we took off with a punch that left everyone on the road in our rear view mirror. As a senior citizen I drive more cautiously, but when it was my turn at the wheel, I couldn’t help but accelerate to the max. What a ride! I also liked the steering—firm, nimble and responsive. The slightest turn moved the car decisively, making me realize that it needed two steady hands on the wheel. A quick U-turn in the middle of Pacific Coast Highway—something not recommended by good sense or the police—was a delight.  I also liked the tight, firm ride—nothing spongy about it. The regenerative braking, I confess, made me nervous. Would I need a  learning curve to master it? Well, as it turned out, I didn’t need much of a learning curve. Once I obtained my car, I felt comfortable and in control of the braking by the time I got the vehicle home.

This test drive made me know that the i3 offered a superior way of driving from anything I had known before. By the end of the drive, I announced to my son that I would put down my deposit early in the week and surrender my Lexus vehicles to CarMax. My son said he would also do the same and give up his Infiniti SUV.  The decision to downsize and to go electric was a big one for our family, but after driving the i3, it left us little choice. The joy of driving the i3, the interior space and comfort, the responsive steering, the firm ride and the  regenerative braking sold us on our first electric vehicle. In every respect the i3 felt, looked and drove like a BMW. We both decided on the REx, knowing that it would meet 90% of our driving needs—and indeed it has.

The drive’s the thing and that’s what sold us. Since I had zero knowledge and experience with electric vehicles, just to make sure that I hadn't confused lust with love, rushing into something I would later regret, I arranged a test drive with a Volt later the same day. The Volt had good acceleration but nothing like the punch of the i3.  Also, the seats were a tad too much like all the GM seats I had known before as was the ride itself—a tinge on the soft side. Further, the interior seemed old and not very inspiring. Driving the Volt reaffirmed my decision to purchase the i3.

Only after the decision was taken to purchase the i3 did I begin to investigate the world of EVs and their multiple advantages. Entering into an intensive period of study, I became like all converts something of a zealot which I continue to be at the time of this writing. I am in conversation with several solar panel companies to get the best equipment at the best deal. My son and I each put down our deposit on the Launch Edition of the i3 believing that this was the only vehicle that would be available in the states in the near future.  The roll out was long and contained all too many disappointments; near the end of our wait, my son decided to throw in the towel and purchased the John Cooper Mini Countryman in place of the i3. At least he is driving a more efficient gasoline powered engine than when he was behind the wheel of his SUV. 

All the things I liked about the i3 that led me to buy it I still like—and like even more than when I did my test drive. I’ve come to appreciate the Harmon Kardan sound system which in a cabin that is quiet (except at freeway speeds), enhances my listening pleasure. Speaking of the quiet cabin, it is not always as quiet as I would like. At city-street speeds, its as quiet as a church mouse. But on the freeway, especially as I approach 70mph plus, wind noise is noticeable, sometimes quite noticeable. If BMW can dampen that in the next iteration of the i3, it would make the drive even more enjoyable. 

Sometimes it’s the little things that are most distressing. My biggest problem and that of my guests is getting the tongue of the seat belt into the buckle. While I am older and have lost strength in my hands, younger and abler persons also have difficulty. Sometimes it takes quite a bit of hard pushing to buckle up. Do I wish for a battery with greater range, of course, but I’ve learned to live with it. I like the light weight of the vehicle which contributes to the i3’s acceleration, handling and efficiency. If there was one thing I would say to BMW it is, resist all the calls for significant additions if it means making the vehicle heavier. 

In light of the limitations of the battery, the REx has been indispensable to my driving needs. The smooth transition from being on the battery to the point when the REx kicks in is quite remarkable. I never feel or hear it nor do my passengers (actually one passenger in the back seat thought he heard a slight hum).  I did have a significant loss of speed coming up a long, steep incline at the end of a 211 mile round trip. My companions and I couldn’t help but laugh as we knew this might happen but had not experienced it at any time earlier in the trip when we encountered steep inclines and were still on battery. What this means is that, understanding the limitations of the REx (all cars have their limitations in one respect or another), I need to plan my trips more carefully which I will in the future. The “slow down” neither diminished my ardor for the car nor my appreciation for its overall abilities and quality.

I’ve set the vehicle to charge at midnight when electricity rates are at their lowest. I purchased a ClipperCreek HCS 40 which works like a charm and cost me considerably less than the charger BMW is selling.  From the standpoint of technology, this was the easy part. I confess that I find the i3’s software daunting and even after 1,000 miles, I am still only half way through learning the software’s mysteries.

One of the most delightful aspects of owning the i3 is the number of people who wave me down on the street, or give me a thumbs up on the freeway, or stop me at my favorite coffee shop or at the market, or encounter me in other ways asking me questions about the car or just admiring it. Recently an eight year old English boy on vacation in California approached me with his mother gushing facts about the i3. He is a devotee of Top Gear and knew much more than I about the car. I know that some commentators think the i3 is an ugly little beast, but the people who come up to me all seem to be intrigued by its looks. I hope that their inquisitiveness turns into sales. 

My own private "gas station" in my garage. How great is that?!

Several people helped me throughout the roll out of the i3. My dealership went out of its way to find answers to all my inquiries even when they had little experience with the vehicle. Stephan, my Client Adviser (salesman in ordinary English) actually knew something about the i3 and was an anchor keeping me from drifting away. BMW North America, despite the glitches in the roll out, was enormously helpful when I reached out to them. No sooner did I reach out to them than they reciprocated frequently, reaching out to me. I want to thank Jacob Harb of BMW North America who, put in charge of the roll out, became the focus for everyone with a grievance, all too many of which were legitimate but many of which were not of his making. Jacob reached out to me after I contacted BMW, giving me reassurance and easing the process.  Good communication is more than fifty percent of addressing problems even when solutions are not readily available. Like the oak in a gale, Jacob may have bent but he did not break and he saw the roll out through to fruition. Finally, without Tom Moloughney who captained the ship during the long process, leading the charge for the i3 against its frequent critics, providing answers to questions no one else seemed to have, defending the vehicle even while the process was discouraging, providing a communication link to BMW and giving us certainty that there would be an i3 in our future, I say without Tom I would have and I think many others would have said, nice try BMW but now I am going back to what I know and can rely on--a gasoline engine. Thank you Tom.

For those that don't know, Fred has been a  follower for a while now and has commented on this blog and it's really great for me to see him finally take delivery of his i3 and now tell us his story here. I appreciate the kind words he had for me at the end but honestly I wanted to remove that part. Fred insisted it remain and told me that he didn't want me to post the story if I deleted it. I know I've said it before but one of the great things about maintaining my electric car blogs has been the interactions I have with the followers through the years. I'd like to take a moment to thank all of my followers for their continued support. Without your comments, emails and encouragement I would have stopped doing this a long time ago!  

Mountain Climbing With an i3 REx

Loveland Pass, Continental Divide, Colorado. Elevation 11,990 ft

A few weeks ago Don Parsons of Denver, Colorado took his i3 REx on a 128 mile road trip from his house to Loveland Pass (Continental Divide, Colorado). On his way up to the 11,990 ft elevation of Loveland Pass he stopped at Beau Jo's Pizza for lunch and to charge on their public ChargePoint EVSE where his i3 REx accepted 8.9kWh's of juice to help with the rest of the climb up the mountain. 

The car showed 18 miles remaining at the top of Loveland Pass, and he nearly made the trip entirely on electricity when 62 miles later the range extender kicked on and he was only 2 miles from his home. 

The trip summary: 
-64 miles each way
-8,960 feet of climbing, 2329 Feet of descending on way out
-2329 feet of climbing, 8,960 feet of descending on way back

Having heard about this Continental Divide conquest, I asked Don if he wanted to write a guest blog post about the trip, but he offered to do one better. His next challenge was to take his i3 REx up to the summit of Mt Evans which is the highest elevation paved road in the US. The trip would take him over 14,000 feet above sea level and would most certainly push the range extender beyond its limit. This was not the kind of road trip BMW envisioned people taking the car on when they designed the REx, but nonetheless they have to expect some people like Don would do just that. So what happened? Read Don's words below to find out:

I’ve had my BMW i3 REx for almost two months now and haven’t really used or tested the REx engine.  Before today, I’d driven about 1750 miles total with only about 10 miles using the engine.  I decided to drive from my house in Denver to the top of Mt. Evans and return without stopping for gas or topping off the charge.  Using the REx engine in the mountains can be tough because the output of the small engine can’t really put out enough power to go both highway speeds and climb uphill.  However, the road to the top of Mt. Evans is pretty narrow, has steep drop-offs, no guardrails and a lot of cyclists sharing the road so you really don’t want to go much faster than 35 mph.  For this reason, I thought the small engine could hopefully handle the climb.

For those that don’t know, Mt. Evans is the highest paved road in North America with an elevation of 14,130 feet above sea level!  I live in Denver which is at 5,280 feet above sea level.  It’s 63.5 miles from my house to the top Mt. Evans.  With some up and down hill climbing, the total ascent is 12,446 feet and the total descent is 3,686 getting to the summit.

I set the car into Eco Pro+ and set out on city streets of Denver, then I-70 west up the mountains to Idaho Springs.  Mt. Evans highway winds its way south from Idaho Springs to the Mt. Evans summit in 28 miles.  When I originally entered the destination into the navigation system, the guess-o-meter said 61 miles of range.  I tried to keep the cruise control set to about 5 miles over the speed limit.

I was surprised to find that the Rex engine didn’t turn on until about 52 miles into the drive (about 10 miles from the summit) with a total trip average mi/kWh of 2.8 when the REx kicked on.  However, about 1 minute after the REx turned on I got a Brake error message that ended up making the brake pedal feel stiff and pretty much unusable.  Fortunately, I was still heading uphill and the regen seemed to be working normally.

I could hear the engine speed up during the straight parts of the switchbacks and as I slowed down for the sharp curves, the engine almost immediately slowed down as well.  I never really wanted to travel faster than 35 mph so I didn’t notice any performance hit until near the summit.  On the last few switchbacks, I put my foot to the floor and couldn’t get the car to travel faster than 26 mph.  At close to 14,000 feet of elevation, the engine was probably severely limited from its usual output at sea-level.  I’ve heard people say that an ICE reduces power output by 5% for each 1,000 feet of elevation.  In any event no other cars were traveling any faster than 25 or 30 mph so I didn’t feel unsafe.

I finally made it to the top at 14,130 feet!  The temperature had gone from 68 degrees in Denver to 35 degrees and quite windy.  This road usually shuts down for the winter sometime in September so they will be expecting snow to start accumulating up there pretty soon!

As I was getting ready to head down, I was worried about whether I would have any use of the brakes since I had turned off the car and walked around the summit for about 5 minutes hoping the error would reset but it didn’t and I still had a stiff brake pedal.  Since it was 35 degrees up there, I was pretty cold and didn’t feel like waiting any longer so I thought I would start to head down and see how well the regen worked to keep the car in control.  You can imagine how happy I was to have such a high regen rate because I felt like I was in complete control all the way back home.

During the descent from the summit down to Idaho Springs I was excited to see that the regen had built up a full 25% of the battery SOC and the guess-o-meter said as high as 28 miles of range on the battery.  I drove home significantly on battery but the REx kicked in a few times where there was some climbing.  It also stayed on once I got out of the mountains but I was easily able to maintain 75 mph on the highway leading east back into the city.

Here's a screenshot of the elevation and speed of the whole trip

Some stats on the whole trip.  I traveled 127.6 miles and averaged 4.9 mi/kWh and average speed was a total of 39.6 mph.  I used a little over a quarter of the rex tank which I think is pretty minimal for traveling almost 130 miles! As you can see from the picture, the brake error was still in place when I arrived home.  However, after being on my EVSE for a little over an hour, everything was cleared out and a quick trip to grab lunch showed that everything was back to normal.

I should point out that I haven’t gotten any software updates yet as I haven’t been able to set aside the time.  Until this trip, the only error I’ve seen from the car is the Check Engine Light, which remains illuminated. There is a software update that will eliminate this waiting for me at my dealer, so I guess it's time to get the car into the shop for the updates.  Hopefully the brake error is related to the 12v battery issues that others have discussed and will also be fixed with the latest software version I'll be getting. 

When I thought about getting the i3 Rex, I figured that I would use the battery over 95% of my driving miles.  So far, it seems like I’m using the battery over 97% of my miles.  That said, I’m still happy to have the Rex as it completely takes away any range anxiety when I’m traveling in the flats of the front range of Colorado.

What about the mountains?  I was concerned about using the i3 REx in the mountains and still believe that having a REx hold mode similar to the European version of the i3 or the Chevy Volt would make this an even more enjoyable car in Colorado.  That said, a couple CCS fast chargers placed strategically off I-70 would go a long way to helping the issue.  Locations in Idaho Springs, Silverthorne (where the 8 Tesla Superchargers are located) Copper Mountain, and Vail would be ideal spots to get a quick top-off and be truly useful in the mountains.  I’ve also kept my 335xi for long distance ski trips since it has all wheel drive and is still a great car. However, even without the fast chargers I was able to make it to the summit and home without a problem.

I’m very happy with the the i3.  The performance, handling, smoothness, and quietness all contribute to a great experience.  Like others have said, it’s hard to go back to a regular internal combustion engine after experiencing electric!

Real World Range Test: BMW i3 vs BMW ActiveE

Now that BMW has begun to deliver some BEV i3s to the ActiveE Electronauts, some of those in the ActiveE trial lease program who haven't yet gotten their i3 have been asking how the i3 compares to the ActiveE. Questions on ride quality, acceleration, handling and charge rate have been asked, but the biggest concern is: How does the range compare? After all, with electric vehicles, range is paramount.

So I got together with Michael and Pamela Thwaite who just last week picked up their Ionic Silver i3 and we mapped out an 80 mile loop that would include roughly 50% highway and 50% secondary and tertiary roads. While everybody has different driving needs and patterns, it was our hope that this course would provide an evenly balanced mix of different driving conditions. That being said, this wasn't a carefully controlled scientific experiment. We didn't weigh ourselves to make sure both vehicles were carrying the same weight, we didn't calibrate our speedometers or record the barometric pressure so please don't bother commenting on why this was a flawed experiment because it wasn't perfectly controlled. We did make sure we had proper tire pressure, we took turns following and leading each other and we tried our best to maintain the same constant speeds. We drove in the default (Comfort Mode) driving mode and didn't use Eco Pro driving mode at all. We met on Saturday morning at my restaurant which has two ChargePoint EVSEs in the parking lot and after about two hours of charging we set out with Pamela driving their i3 and my wife, Meredith, driving my ActiveE. Michael and I were the co-pilots so we could live blog the event, post pictures on social media sites and make sure we stayed on course.

Both cars charging up for the challenge at my restaurant in Montclair, NJ.

With both cars fully charged, the ActiveE showed an estimated 86 miles of range, while the i3 predicted 98. Which will be more accurate?

It was a warm, cloudy day with temperatures in the 80's. We knew we would need the air conditioning so we agreed to both use it only when we were driving over 45mph and under that we would just open the windows. The first stop, about 20 miles in, was the headquarters of BMW of North America. We figured it was an appropriate destination and since it was a Saturday they wouldn't mind us parking in front of the main entrance for a photo op. We were pleased to find a life sized i3 decal applied to the glass of the front doors. BMW is evidently proud of their first all electric vehicle. At this point we had both used 19% of the available battery. I was surprised the i3 was holding its own, especially since that leg was about 75% highway. We did drive the speed limit on the Garden State Parkway though, and stuck to about 60mph. I'm sure if we drove faster the i3 would have used more battery than the ActiveE. Still, I really expected the ActiveE to jump out to an early lead since we were driving at highway speeds for most of the first leg.

The next leg of the journey would be about 40 miles, with the first 30 miles or so on all secondary and tertiary roads and we would end up in Denville, NJ. Michael and I were trading texts during the way and for at least the first 20 to 25 miles of this leg (a total of 40 to 45 miles driven) we were still nearly dead even in battery state of charge with the ActiveE having a 1% advantage with battery state of charge.  On route to the Route 80 leg (which would be our highest speeds of the day and all uphill) we were driving on Route 23 at 50 to 55mph and the ActiveE started to gain an advantage of a few more percent.

Driving the back roads of Bergen county was a pleasure on a nice sunny Spring day

We took turns following and leading each other for the entire route.


Then came the blow that the i3 couldn't recover from. Driving on Route 80 upgrade at the 65 miles an hour speed limit for about 10 miles finally gave us the separation we expected. We were 60 miles in (59.8 exactly) and the ActiveE now had a 6% state of charge lead (46% to 40%) and a predicted range of 9 more miles (40 miles to 31 miles). This clearly reinforces what many of us imagined. The i3 is a warrior on low speed driving, but at faster highway speeds it's a bit out of its element and the range will be substantially compromised.  At highway speeds the weight of the car isn't nearly as important as its aerodynamics, the exact opposite of low speed driving where weight influences energy use much more. The lightweight i3 has a respectable Cd of .29, but it is tall and has a large frontal area which increases its CdA (the combination of drag coefficient and frontal drag area) making it less than ideal for cheating the wind resistance at highway speeds.

The final 20 miles were about 30% highway (this time down hill most of the way) and 70% secondary roads with about 4 miles of stop and go, traffic light to traffic light driving. We decided to make one last stop at an appropriate destination which happened to be along the way. We stopped at the Thomas Edison National Historic Park in West Orange. What would be more appropriate for an electric car challenge anyway?

After the quick stop we headed back to Nauna's and finished the day driving exactly 80 miles. The ActiveE won the range challenge by 6 miles. Here are the final statics:

2011 BMW ActiveE
Remaining SOC: 27%
Estimated miles remaining: 22
Trip efficiency: 4.1 miles per kWh
Total miles: 102

2014 BMW i3
Remaining SOC: 20%
Estimated miles remaining: 16
Trip efficiency: 5.4 miles per kWh
Total miles: 96




So adding the mileage driven to the remaining mileage the i3 ended up with 96 miles of range and the ActiveE with 102. The i3 actually came very close to predicting the actual range and was only off by 2 miles since it predicted 98 miles of range when it was fully charged that morning. My ActiveE actually beat its range prediction by 16 miles, but that is because my regular driving routing is mostly highway so the car has learned to predict the range based primarily on high speed highway driving. All in all the i3 fared about as well as I expected. It is an incredibly efficient electric vehicle and is in fact now the most efficient car sold in America. However the ActiveE has a battery that is nearly 50% larger (21.6kWh's to 32 kWh's) than the i3's battery and in the end battery size beat efficiency. If the i3 had just a couple more kWh's, I'd be writing a different ending. BMW has been billing the i3 as its "Megacity" car. That was even the codename during development and they weren't kidding. It is much better suited to live its life on congested city streets than it is roaming the high speed highways of the US and the Autobahns of its homeland. I would speculate the i3 will only go about 70 miles if driven all highway, and that's at the 65 mile speed limit. If you were to increase that to 70 or 75 miles than the range will likely drop to 60 to 65 miles. However if you were to drive on secondary roads at around 35 to 40mph, I suspect 100 to 110 miles would be easily attainable in moderate temperatures when you don't need the air conditioning or heater much. So if I were rating the range of the all electric BMW i3, I'd say 60 to 110 miles, conditions provided.

The Thwaite's i3 topping off after the range challenge

One last no-so-small detail. The i3 we used is brand new, while my ActiveE is 28 months old and has 20,100 miles on it. Based on my recorded data I believe its battery has lost between 8% and 9% capacity. If you factor that in, it's clear that while my two year old ActiveE has a slightly better range than a new i3, it had a substantially better range when it was new. Probably about 15% more, which actually coincides with the EPA range ratings for both vehicles.

BMW i3 BEV vs REx: Your Purchase Matters

On REx models the i3's range extender sits next to the electric motor above the rear axle.

Many people considering a BMW i3 are a bit torn between the full electric version (BEV), and the range extended version (REx). What they may not know is their decision will indeed help BMW decide what electric range their future EV offerings have.

Now that the EPA range rating for the BEV i3 has been announced at 81 miles per charge customers can finally decide if they BEV i3’s range will suit their needs. If it doesn’t and they still want an i3, their only choice is to fork over the extra $3,850, and get the range extender. There are electric vehicle enthusiasts that consider this unacceptable because they don’t ever want to put gasoline in their electric vehicle, it just seems wrong to them. Others don’t mind, since they will be driving on electric the vast majority of time and using a little gas is OK with them.

Basically there are four main groups of perspective i3 purchasers:

1)      They are interested in the i3 but the 81 mile EPA rating is just too low for them and the range extender is out of the question. They walk away from the car and consider their other electric vehicle offerings.

2)      The 81 mile range works for them. They get the BEV i3 and understand its limitations.

3)      They really wanted the BEV i3 but the range rating was too low for their comfort so they reluctantly ordered the i3 REx. (I fit in this box)

4)      They really liked the idea of the range extender from the start and wouldn’t have bought an i3 without it. The ability to drive primarily on electric but have the range extender there for the few times they need more range is perfect for them. Not ever worrying about getting stuck on the road because they ran out of charge or a public charger was broken or blocked is paramount for these people.

Of course there are other factors, like local incentives and especially HOV access in California, but these are generally the four boxes the typical potential i3 customer will fit in. It will be interesting what the percentage of BEV buyers to REx buyers are, and don’t think BMW isn’t watching that very closely. I have personally spoken to BMW mangers that have said the breakdown of BEV to REx sales will give BMW a clear indication of what range people are comfortable with. If BEV sales dominate, BMW will take that as verification that the range they gave the i3 was right for this vehicle and perhaps consider future low-range EV's. Conversely if the majority of i3s sold are range extended versions, or if sales in general don’t meet expectations they have a clear message: The potential customers didn’t believe 81 miles per charge was enough, especially for premium brand EV and they are more likely to make the next EV they offer have a longer range. In other words, your purchase is your vote. Buying a BEV i3 is telling BMW that 81 miles is fine, and buying a REx i3 is telling them it’s not.

Hopefully BMW will break out the sales of the BEV i3s and the REx i3s in their monthly sales reporting instead of just including them in one group. That may just help to give us a better idea of what to expect next from the i brand.
