BMW i3s traction control tech going in all BMW, Mini cars

The BMW i3s is essentially a warmed-up version of the i3 electric car we all know and love. The performance boost isn't huge — just 14 horsepower and 15 pound-feet of torque — but it also gets a new suspension, wheels and tires as well as an improved traction control system. We found the car to benefit from all the updates when we drove it for our First Drive Review, but now BMW has offered up more details on just how the traction control system of the i3s helps make it better to drive. The company says it'll expand the technology to all future BMW and Mini models as well. The i3s's system is calibrated to help it to pull away quickly from a stop, making full use of the instantaneous torque offered by the electric motor. It also improves stability when accelerating out of corners, when using regenerative braking and, of course, when the road conditions are less than ideal. The results are palpable, and with the other improvements the i3s definitely feels stronger off the line, as we found on our drive. It's also about a half-second quicker to 60 miles per hour, at 6.8 seconds. The secret is in the response time of the stability control, which BMW claims is 50 times faster than the conventional system. This is made possible by moving the control process into the powertrain itself, rather than a remote unit. This reduces the signal path and, thus, the response time of the traction control system. BMW's Head of Chassis Development, Peter Langen, said of it, "With their high levels of torque and instantaneous responses to every movement of the accelerator, electric motors already make significantly higher demands on driving stability systems than conventional power units." While engineered to make the most of the electric motor, BMW says the shorter cycles of this traction control system show promise for internal combustion vehicles as well. As such, we'll begin to see the improved technology applied across the BMW and Mini lineups going forward. Related Video:

BMW predicts US will be biggest i8 market

BMW will be showing a production version of its new i8 plug-in hybrid supercar at the upcoming Frankfurt Motor Show, and while we're quite excited about seeing the company's second i product in the flesh. According to a new report from Automotive News Europe, BMW is expecting its largest markets to be the United States, United Kingdom and Germany. Notable for its absence in that list is everybody's favorite mega-market, China.
Automobilwoche, a German-language publication of Automotive News Europe, spoke with the i8's product manager, Hendrik Wenders, who declared, "The US will be by far the largest sales market for the i8." Wenders stops short of actual mentioning what percentage of i8 sales will be in the US, but does mention that it should arrive in showrooms around the world in about nine months. The simultaneous rollout will occur in 50 different countries.
Check back for our full coverage of the i8's debut at the 2013 Frankfurt Motor Show. If you just can't wait until September, then check out our first drive of the i8 Prototype.
