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 pitting self-drifting car against drift champion

The BMW M235i certainly makes a capable drift machine. Last year, the Bavarian brand had five of them with the tail out in unison in South Africa for the Driftmob. The coupe even proved that it could slide without a driver's intervention. For the latest sideways stunt, the company wanted to know which was the better drifter: an autonomous car or a human. This clip is just the trailer for BMW's entire drift challenge video, and it seemingly gives away the ending of the whole thing. We're sure, though, that there must be something more to the stunt than what's on display here. The driverless Audi TTS from Stanford University was reportedly slightly faster than an amateur racer around Thunderhill Raceway Park recently, and BMW has also been working at this problem for years with things like its Track Trainer. Regardless of how you feel about driverless cars, it's amazing how quickly autonomous tech is progressing – even on the track.

NHTSA gives okay for three automakers to skirt tire-related recalls

BMW, Honda, and Mercedes-Benz are all going to avoid small recalls, after the National Highway Traffic Safety Administration issued petitions for "findings of inconsequential noncompliance" to the three manufacturers, according to Tire Business. Basically, the petitions allow the brands to avoid recalls for some very, very minor issues.
BMW had tire placards on 364 X6 M CUVs that stated the car could only handle four passengers, when in reality it had room for three in the back. Actual plausibility of fitting three real humans in the slope-roofed Bimmer aside, the Munich-based manufacturer argued it was inconsequential, as the placards were correct regardless of the number of passengers.
Honda's case focused on 212 2011 and 2012 Acura TSX sedans equipped with 18-inch wheels. The TPMS systems on these cars were set for 17-inch wheels, rather than the larger hoops, but even with the lower settings, the tires maintain adequate load capacity.
