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:

Two rare Alpina BMWs given the Petrolicious treatment

Alpina is getting more and more ink because of because of that rolling cannonade known as the B7 and its closer ties with BMW. The company's tuning business dates to 1962 when Burkard Bovensiepen began fiddling with Weber carburetors, then his company began racing in 1968 and was eventually certified as an automaker in 1983.
Two of its rarer specimens from those early years have gotten a glance from the folks at Petrolicious: the E24 B10 and E24 B7S. Based on the BMW 6 Series, the Alpina versions made one of the most special coupes from the Eighties even more so. According to the video, there were only 44 B10s made, and the turbocharged, 333-horsepower B7S - this was in a luxury coupe in 1982, mind you - saw only 33 examples produced.
You won't be sorry to find out more about them - and see how they run - in the Petrolicious video below.

History of BMW touring cars looks splendid in Adrenalin trailer

More high-quality documentaries about the history of motorsports are always welcome. When thinking about racing, we generally focus on moving forward to go a little faster or shave a tenth of a second off a lap. There's not much time to look backward. It's too bad, because there are so many fantastic stories from the sport's history. Thankfully, an upcoming doc is taking on the challenge of telling some of these tales, and it looks like a movie not to miss, especially for BMW fans.
Adrenalin - The BMW Touring Car Story mixes high-quality, vintage footage with new interviews from many of the drivers of these machines to craft what looks like a fantastic experience. Covering the period from the '60s to the modern DTM era, just the trailer shows racing from the 2002, 3.0 CSL and of course the E30 chassis M3 of the '80s. You also get to hear from legends behind the wheel like Hans-Joachim Stuck, Johnny Cecotto and Joachim Winkelhock telling their stories.
Adrenalin comes out in November on DVD, Blu-Ray and on-demand. Check out its trailer above for a taste at what it's aiming for. The documentary definitely looks like one to watch.
