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:

Next BMW 6 Series, M6 to take aim at Porsche

Since BMW reintroduced the 6 Series line back in 2003, the big two-door has happily sat as the brand's de facto grand tourer. That will allegedly change come 2017, as Car is reporting that Munich will put its coupe on a diet with the so-called G15 generation, allowing the 6 to go after the likes of Porsche. All three of the current 6's body styles will be carried over for 2017, with the base 640i Coupe trimming over 500 pounds of body fat, to around 3,450 pounds. Even the droptop is getting some lipo, dropping from 4,255 to around 3,750 pounds. It's unclear how much the Gran Coupe will be lightened, as it will be the only member of the 6 Series family that's growing in size. BMW will stretch the wheelbase of its fullsize, four-door coupe, which should make it decidedly more sedan like. The weight savings come thanks to a new modular architecture that promises a "more advanced material mix." That means carbon fiber, high-strength steel and aluminum elements, and even some titanium and magnesium bits. Along with xDrive all-wheel drive, Car is promising new six- and eight-cylinder engines, with the 640i's 3.0-liter, turbocharged gas engine producing 347 horsepower while the diesel mill turns out 333. The 4.4-liter V8 of the 650i will deliver 476 ponies, while the range-topping M6's twin-turbo V8 will reach the magical 600-hp figure. Of course, we can expect to hear more about the next 6 in the coming months and years. In the meantime, though, let us know what you think of Car's positing below, in Comments.
