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. :)

BMW i3 Places 2nd in European Car Of The Year Voting

Some say there are no moral victories and if you don't win, well, you just lose. I think that may apply to sports more than in other types of competitions, like say, the European Car Of The Year Award.

The BMW i3 finished 2nd to the Peugeot 308, and it was in fact by a substantial margin. However it is worthy of noting that the i3 did finish ahead of the Tesla Model S, which is largely considered the best electric car available. In fact, some automotive journalists say the Tesla Model S is flat out the best car available, electric or otherwise. So in this case, while I'm sure BMW had hoped to win the award, I think the consolation prize of finishing ahead of the Model S was definitely something they privately celebrated.

Autocar was the first to reveal the winner, getting the scoop on everybody. I'm actually here in Geneva now at the Geneva Motor Show covering it for InsideEVs and I didn't even know until I read what they posted! It seems Autocar may have in fact been surprised the i3 didn't win, and blamed the loss on the i3 and the Model S splitting the "electric vote". I'm not too sure I agree with there being an "electric vote" though, and the margin of victory was large enough to consider it a clear victory . However I really know very little about the voting process for this honor and perhaps Autocar knows something about this that I don't.  Here is what they had to say about the results:

“Peugeot wins ECOTY ahead of BMW i3 and Tesla Model S, which clearly split the electric vote. No quarrel with the 308, which is a very well sorted example of its kind, but still feel it’s an opportunity missed to pass over a revolution like the i3 in favour of something so very conventional.”

Here's how the voting went:

Peugeot 308: 307 votes
BMW i3: 223 votes
Tesla Model S: 216 votes
Citroen C4 Picasso: 182 votes
Mazda 3: 180 votes
Skoda Octavia: 172 votes
Mercedes Benz S-Class: 170 votes

So while the i3 didn't take home the trophy, it's clear the voters were impressed with what the i3 brings. To finish ahead of the Model S is pretty incredible, because the Model S is really an incredible car in its own right. So even without a win, this bodes very well for the i3. This is definitely an example of a worthwhile moral victory if I've ever seen one. Now we'll see if the people agree with the results. So far the demand has been very strong for the i3, but will that continue once the original pent up demand subsides and production ramps up to full volume? That's the three billion dollar question that BMW is praying for.

The action around the i3 on the show floor was very good, as it was basically surrounded with journalists all day. I was a little surprised by this because the i3 isn't "new" to the auto show circuit. It may be just launching for the public but journalists have had access to it at many of the past auto shows and by now I would have expected the buzz to have subsided a bit. Perhaps there was renewed interest because of the 2014 European Car Of  The Year competition.
