BMW i3 Training Autocross Video





*Hat tip to insideevs.com for finding this first!


BMW has been holding i3 training events to get the new BMW Product Geniuses up to speed on what they need to know about the car. As I have written here many times, there is so much about this car that is completely different than anything BMW has ever sold before that they really need to dive deep into the training of their client advisers and especially these new Product Geniuses. As good as the car is, if they fail to have the ability to properly help the customer decide if the car is right for them, then they won't sell nearly as many as they could have. This is going to have to play itself out before we can gauge if BMW did indeed do everything they could have to give the dealers the tools they need to sell these vehicles.

However in my opinion this video is promising. Not only is BMW holding training sessions where the Product Geniuses will learn about he cars, but they are getting the chance to take once out and do an autocrossing session in one. Plus, in addition to getting to drive in the i3, they also get to drive in a couple i3 competitors, like Chevy Volts and Nissan LEAFs while they are there so they can see how much better the i3 performs.

I assume the above video was taken by one of the Product Geniuses during one of the training sessions and posted on YouTube. It's not a professional quality video by any means, but it does show he was indeed impressed with the i3's performance.

BMW ///M i3: It's Coming - Soon!



A full range of official press photos of this semi-camouflaged Mi3 will be released a couple days before NAIAS in two weeks. This is the only one I was authorized to reveal.

About six months ago, Eric Loveday of InsideEVs.com wrote this article that predicted the BMW M performance division won't be making an M version of the upcoming BMW i3 or i8. I've known for a while now that that was not true, but the information I got from BMW was under embargo until now so I couldn't comment on it previously. I finally got a chance to look at a pre-production ///M i3 last week. The car I saw didn't have all the body work or the special wheels that the ///M i3 pictured above has since this one is being used for internal testing here at BMW's North American headquarters, but it did have all the performance upgrades and ///M badging.
I was lucky to be one of only a few people to get a sneak peak of the M i3 before its unveiling at NYIAS in two weeks.

Perhaps this was the intention all along, or maybe BMW changed their minds along the way, but both the upcoming i3 and i8 plug-ins from BMW i will get the "M" treatment. Back in August of last year I did a post about BMW offering a Sport Version to satisfy the desires of the performance minded i3 buyers and it turns out BMW was definitely listening. Honestly, I would have really been surprised if the i3 didn't have an ///M variant or at the very least, as I suggested, a special edition "Sport" i3.

One person posted this on Bimmerpost. Perhaps they were wishing for an ///M i3 also?
Recent articles have popped up around the web eluding to the fact that BMW was working on a "special edition" i3 and that it would have a more aggressive appearance, but many assumed that would be reserved for the i3 coupe which is expected to launch about a year after the 5 door hatchback i3 that is available now. That's may be so, but I have confirmed the ///M i3 will indeed be a modified version of the current i3 offering, and it will indeed be available soon after the initial US i3 launch. If the i3 concept coupe does make it to production, it would seem likely to get the same ///M treatment as the 5 door hatchback is.

I knew all along that if BMW really wanted their customer base to welcome the i3 and accept it as a true BMW then they would have to offer a performance version, just like they do with their other models. Performance is in BMW's DNA, it's what distinguishes a BMW from the other premium brands. To not make a performance version of the i3 would seem to be a mistake in my opinion. However I didn't expect it to come so quickly. I figured the ///M i3 would be launched sometime in 2016 to invigorate interest once the initial excitement over the i3 began to wane.
TopSpeed (www.topspeed.com) had their go at what they think the ///M i3 will look like
Loveday wrote, "We suspect that BMW will make available several performance-enhancing products for both the i3 and i8 in the near future, but both an i3M (Mi3) and an i8M (Mi8) seem to be no-goes." That's certainly understandable since BMW had said on more than one occasion that they will not be tapping the M performance division to tweak the i3 & i8.  So what do I think changed their minds? My guess is surveys; it's that simple. Last September I received an email survey from BMW i asking me about 50 questions regarding my interest in the i3. I'm not sure if I was included in the survey because I drive an ActiveE or just because I was signed up on the main BMW website for i3 information, but the survey focused on what options I would pay extra for. Almost all of the questions centered around paying for more range and paying for more performance, with one of the questions specifically asking if I would pay and additional $8,000  for an ///M version of the i3.

Fortunately the majority of the respondents must have answered as I did, saying yes we would be willing to pay extra for both range and performance. Yes, I know the i3 is focused on sustainable personal transportation for an evolving world, but hell, there's always the weekends, and i3 owners will want to autocross their cars just like 3-Series owners do. That's part of the BMW heritage, and part of why people gravitate to the brand.
TopSpeed's ///M i3 guess shown in coupe' form
Over the two weeks we should be getting all the details for the ///M i3 & ///M i8 models. The New York Auto Show opens on April 15th and both ///M cars will make their world premiers there. This will coincide with another special announcement regarding never-before released information about DC Fast charging for the i3, so if you are an i3 fan, head to the NYIAS this year. The Press preview days are April 16 & 17th, with the show opening up to the public on Friday the 18th and running until Sunday, April 27th.
The ///M i3 wheels will be a modified version of the optional 20" wheels available on the i8
Opening ceremonies of NYIAS will include Mayor de Blasio declaring the show officially open and that will take place at the BMW exhibit, likely next to the ///M i3 and ///M i8. This all but guarantees that pictures of the new performance-orientated plug-ins will be plastered in every newspaper in the NY metropolitan area. Unless BMW strategically places their gas offerings there which would be very disappointing.

Little is actually known about the spec's of the ///M i8, but I do have some of the details on the ///M i3. Besides a more aggressive exterior styling, including a new front grill and spoiler, monochromatic paint (Yes, the black hood and rear diffusers will be painted the color of the car) a larger rear spoiler and fender flares. The standard wheels on the ///M i3 will be the 20" Sport wheels that are currently available on the i3 (the 19" wheels aren't available on the ///M i3). However there will also be a wider wheel offering which puts a 20" x 6.5" wheel on the car with 245/40/R20 Brigestone Potenza S001 Tires. The wheels look very similar to the optional 20" BMW i8 wheels but they appear to be painted black in the press photo I obtained. The upgrade tire size is nearly perfect in diameter and the speedometer will not be affected at all. I suspect this will dramatically improve the handling, but it will certainly come with a price. I'd expect this tire and wheel combo to likely be about a $2,000 option, but for the performance-minded, it will likely be worth it!

Specification-wise all I know is that BMW is indeed using the same motor that the base i3 uses, it's just been modified to increase power output by about 25%. If that holds true, figure on about 210 horsepower and 230 lb-ft of torque. I was told the goal was to get the 0-60 times in the mid 5 second range and with that kind of added power I believe it is definitely within reach since the stock i3 BEV does it in about 7 seconds with 25% to 30% less power. The suspension will obviously be improved for performance and the interior will likely get the usual smattering of ///M badging and special seats which offer more support.

______________________________________________________________________

Now for the most intriguing part of this. The i3 has been designed around the philosophy of weight savings whenever possible. Many of these features will add weight which reduces efficiency. Plus, the more powerful drivetrain will likely use more energy than the stock set-up does. If someone were to drive the car hard (like it should be driven) then the range may only be 40 or 50 miles, and that's just not enough. So I asked if the ///M i3 would be available with the range extender, and was told definitely not; it will only be available in BEV form. Pressing further about the likely limited range of what will be a very expensive 40 mile electric car he replied, "The ///M i3 will have a greater electric range then the standard i3. It will also charge faster and offer technology unavailable in any other electric vehicle on the market." Now this is indeed getting interesting. There are really only two possibilities here that make any sense. It either has a larger battery pack, perhaps utilizing the space where the range extender goes, or BMW is using the higher density batteries that they have been testing in MINI-E mules for a couple years now. These cells are reported to have about a 30% greater energy density than the stock i3 batteries that come from Samsung have, so that would seem to work here.

I wish I could say I've had the opportunity to test drive it, but I didn't. I was only allowed a brief in person look at the one pictured above in Arravani grey which was at BMW NA's headquarters undergoing internal testing and give the BMW Press photo of the semi-camouflaged one on the track. Even without driving it or knowing what it's going to cost, I decided to cancel my Electronaut Edition i3 and place my order for an ///M i3. They aren't officially available yet so please don't call your dealer and ask to reserve one, that won't be possible until after the New York Auto Show. The ///M i3 & ///M i8 will also be available in "unique colors specific to the M division," I'm hoping Melbourne Red is one of them ;)

4/2/14 EDIT: As many of you figured out, this was an April Fools Post yesterday and I want future readers to realize that. If you take a look at the first letters of each paragraph that are in bold blue text you can see that spell "April fools", I'm surprised nobody commented on that here. I hope you enjoyed it and what I really hope for is a real ///M i3 form BMW sometime in the future!

Bridgestone's "Ologic Technology" and the i3





Much has been made about the tall narrow tires on the BMW i3. They are really unlike any tire on any other car currently in production and they certainly don't look like they belong on a BMW. However BMW and Bridgestone did their homework on this, and accomplished the goals they set out to. That was to develop a tire that is not only efficient, but also delivers the performance expected of any BMW.

How did they do it? Ologic technology. Yep, they developed something so new and advanced you have never even heard of it before! So while I as the Geneva Motor Show a few weeks ago, I made it a point to stop by the Bridgestone exhibit to ask about this new mysterious "Ologic Tech". As I approached the Bridgestone area, I could see they had a Capparis White i3 on display with it all lettered up promoting this new Ologic technology, and they even had an award in a case next to it that proudly displayed that Bridgestone won the 2014 Tire Technology International award for Tire Technology of the year! Fantastic! I was even more pumped up to find out what this new Ologic technology was. Could it be a new special rubber compound or tread pattern?  I was about to find out.


Tire Technology International Awards 2014 winner interview – Tire Technology of the Year

So after asking the information desk for someone to interview I was introduced to a Brigestone product manager to answer my questions. I didn't waste any time. My first question was: What exactly is Ologic technology? I don't have the exact words he used but to paraphrase he basically said "Ologic Technology is our way of creating an efficient tire that still offers optimum performance. By using a very tall narrow tire we simultaneously reduce drag, rolling resistance and tire deformation. The height of the tire in relation to the width also increases the contact patch which allows for retain the dynamic driving characteristics of a much wider tire" So Ologic is just a name of a concept, not any specific rubber compound or such? Yes. Alright well that was a little let down because I figured I was going to get a lesson on rubber or tread or something other than what I heard.

So why are they so special? They must have done something right to win the Tire Technology of the Year award, no? Here is an excerpt of how Bridgestone explains why these are indeed special:

"A Unique Concept for a Unique Car
 
BMW has achieved a genuine milestone with the i3 electric car. Doing justice to its unprecedented levels of both efficiency and performance demanded more than just a new tyre but an entire new tyre concept. Bridgestone’s answer came in the form of the ologic technology, which capitalises on the synergies of a large diameter coupled with a narrow tread design. The result is a tyre that delivers significant improvements in aerodynamics and rolling resistance, while still offering outstanding grip in wet weather conditions.

Combining a large diameter with a narrow tread pattern has several advantages. While the tread on smaller diameter tyres is typically inclined to excessive movement or “deformation” during driving, the larger diameter and higher belt tension significantly reduce tyre deformation and therefore conserve energy that is otherwise lost through internal friction which helps to reduce rolling resistance. By the same token, the narrow tread concept improves aerodynamics. The most spectacular achievement, however is that these improvements do not involve a trade-off in terms of safety. The tyre’s long contact patch (relative to its narrow width),  revolutionary tread design and compound still ensure outstanding grip in both wet and dry conditions."



They have obviously done something right because even though they look like they would be better suited on a motorcycle, the i3 handles exceptionally with them. I've spoken to quite a few people now that have had an i3 on a race track and all of them were genuinely surprised at how well the car performed. In a few weeks I should be taking delivery of my i3 and I can the really put the "Ologic Technology" to the test. :)

i3 Modifications, a Sport Version and Fun



I found this photoshopped i3 on Bimmerpost. It looks to me like the creator has the right idea!
Now that we've seen the production i3 and BMW has revealed most of the specifications, I'm ready to begin the modifications! Evidently someone on the Bimmerpost forums is ready also because he used his photoshop skills and went to work on creating his own autocross-ready i3. I like it! It's even in the Laural Gray that I'm leaning towards so that made it all the better.

So this gets me wondering if BMW even realizes there are people out there that will want to modify their i3. BMW has already said there won't be an M version of the i3 and I conformed that with a program manager recently, but that doesn't mean they won't offer modification parts for those interested. After all, BMW cars are some of the most modified of any manufacturer. I hope they aren't under the assumption that just because i3 customers are concerned with things like sustainability, environmental issues, energy policies or just like driving electric that they won't share the same enthusiasm for driving as their combustion car customers do.

I'll take it one step further. Even if they don't cross pollinate the i and M brands, they could still make an i3 Sport version. Give it a special interior, offer it in a unique, bold exterior color, beef up the suspension, put on some real tires and give it a little more torque and HP(I'm sure they can do that with the same motor they have with very little tweaking) and you'll have a 6 second 0-60 car that will have better handling than 90% of all the sports cars out there. Sure it will probably cut 10 miles or so off the range but I think there are many of us out there willing to make that sacrifice.

I know BMW knows the market, and they know people want fun. Even if they are driving a "futuristic, sustainably manufactured" car. All that's great, but it's nothing if it's not fun. :)

BMW Allows The First Journalists Ever To Take A Ride In An i3



An i3 test car going through cold weather testing in Sweden.     Photo: Autocar
For the first time ever BMW has allowed a few journalists take a ride in i3's. One of the test rides took place in Sweden where a small fleet of i3's is finishing up their final cold weather testing. BMW has actually been conducting cold weather testing of the i3's there for over two years now, as the conditions there are perfect for this kind of validation. The other drive happened in Ismaning, Germany at another of BMW's test facilities.

Kacher poses as BMW's Kranz looks on. Photo: Car Magazine
In the past two days Autocar and Car Magazine have published articles on their impression of the experience. It appears nobody was allowed to actually drive the i3, they were passengers. Autocar writer Greg Kable had Patrick Mueller, head of BMW i drivetrain development as his pilot and Georg Kacher of Car Magazine had the privilege of being chauffeured by non other than Uli Kranz, the project leader of BMW i. You can click on the above links to read the full reports and I'll summarize the revelations that I believe are most important here:

1) The i3 is faster than what we thought. Until now BMW had said two things about the speed of the i3. In one instance they said the concept i3 will go 0-100km (62mph) in 7.9 seconds. Then in most recent marketing venues we were told the "Concept i3 goes 0-60mph in under 8 seconds". It's important to note they always referenced the "Concept i3" not the production car. Now for the first time journalists have quoted 0-60 times. Kable from Autocar said the i3 will do 0-60 in 7.2 seconds and Kacher said it will do it in 7.3. The i3 is clearly going to be a quick car. My MINI-E did 0-60 in about 8 seconds and it was a blast to drive. The ActiveE is no slouch either, but it takes a little over 9 seconds to hit 60mph. Cutting two seconds off the ActiveE time will certainly make for a spirited drive. 

2) The i3 achieved an official 140 miles of range on the European test procedure. What does this mean? Well the 2011/2012 LEAF achieved a range of 107 miles on this same test and that translated into a 73 mile EPA rating. Translated to the i3 that would then give it an EPA rating of 95 miles per charge. I know you can't make that exact assumption, but if you simply roll the numbers and say the i3 achieved a range of 130%(140/107) that's what it converts to and it's all we have to go on at this time. I would be happy if that is the EPA range rating for the i3. I have contended all along that I would prefer a 100 mile EPA rating, but as long as it is over 90 miles per charge, then I believe it will do just fine. It will then have the highest EPA rating of any EV that doesn't have a Tesla powertrain.

The 20" wheels on the concept coupe
3) It will come standard with 19" wheels and 20" wheels will be optional. The concept cars had 20" wheels, but concept cars frequently have oversized wheels that don't make it to production. These wheels are huge for a car of this size. There isn't any production car anywhere that is this small and has 20" wheels! You usually only see 20" wheels on huge SUV's and trucks. The whole concept of these tall wheels and thin tires is to maximize efficiency by reducing rolling resistance and drag, while still providing great road holding for high performance driving. When questioned about how the thin tires can manage to give the car such great handling Kranz said: "It’s not rocket science. All that matters is the size of the contact patch. The 19-inch tires may be skinny, but their tall height generates the same contact patch as a low-section 16-inch MINI tire". Kacher was very impressed with the handling and he said: "The i3’s most awesome dynamic talent is its incredible grip. The made-to-measure tires are about as narrow as those of a 125cc motorbike, yet they hang on almost as tenaciously as BMW’s latest DTM racer."

This is the engine to be used for the REx
4) The range extender will be a 650cc two-cylinder gas engine borrowed from the BMW C650GT motorcycle. When used for the motorcycle it has a maximum of 60hp but on the i3 it will be highly optimized for efficiency, and will run at lower RPM's for a quiet, low vibration operation. This lowers the power output to 35bhp. It will be mounted close to the rear wheels and accompanied by a 2.3 gallon gas tank which will be positioned behind the front axle. This makes sense since the gas filler door is on the front passenger quarter panel. I imagine 35 hp will be enough to allow the i3 to continue at highway speeds of 65-70mph on flat surfaces, but I don't believe it will be enough to allow the car to climb steep grades at highway speeds. It's worth noting that BMW has hinted that the range extender is not meant for full time driving like a Chevy Volt. It's main purpose to to allow you to get you to your destination or the nearest charge point once you have exhausted the battery and allow you to do so without worry of being stranded, it's not designed for prolonged high speed driving. If you frequently need to drive more than 100 to 120 miles or so, perhaps the i3 with a range extender isn't the best plug-in choice for you, but let's wait for the official specifications before we conclude that for sure.

5) Kacher wrote: "BMW has tooled up initially to produce 30,000 cars a year, but this can be extended to 50,000 units if the i3 takes off". I had heard rumors of production estimates being 30,000/year initially but they were never really confirmed. If Kacher got this directly from Kranz then it's really the first time an official production goal was offered by BMW. It's a lofty goal. No other EV has even come close to selling that many in any year, let alone it's first year. One advantage the i3 does have though is it will be available in markets all over the world, unlike many of the other plug in cars that are available today. However the LEAF is available in many countries also and it hasn't hit the 30,000/year mark after more than two years and it's a much more affordable car then the i3 will be. It's difficult to gauge the plug in vehicle market. Government incentives play a big role and so does the proliferation of public charging infrastructure. However the i3 is the only EV in it's price class that will offer the performance and range that it does, as well as an optional range extender and the premium driving experience that is expected of a BMW so it will be interesting to watch how the sales figures progress.

Since I wasn't lucky enough to be one of the first outside BMW to hitch a ride in an i3 I'll just reprint Kacher's conclusion. He makes his thoughts on the car very clear:

"The i3 is shaping up to be a breakthrough electric car. It delivers dynamic thrills like no electric car before it. The steering seems highly involving, the drivetrain’s punch would flatten a Leaf, and the handling and road-holding seem up there with BMW’s best. Ulrich Kranz and his team appear to have succeeded in bringing pure driving pleasure to the environmentally friendly car. We’ll know for sure when we drive the car in summer 2013"
