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:

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

BMW Motorrad celebrates 90 years with new R nineT roadster [w/video]

90 years is a heck of a long time by any standard, and as good a cause for celebration as we've ever seen. That's how long BMW has been making motorcycles for, and it's celebrating with the retro cafe racer you see here - as promised and previewed.
Dubbed the R nineT (for 90 years), the latest product from BMW Motorrad traces its roots back to the original 1923 BMW R 32. And like the original, it's powered by a boxer twin - in this case, a 1,170cc air- and oil-cooled unit delivering 110 horsepower and 88 pound-feet of torque. All that muscle is packed into a classically-styled roadster that looks ready to line up next to a Moto Guzzi Griso, Triumph Thruxton or Ducati SportClassic.
The neo-retro styling drapes a unique tubular steel spaceframe chassis that uses the engine as a stressed member. The inverted telescopic front fork is borrowed from the S 1000 RR superbike and a paralever swingarm with spring strut suspends the rear. That's where you'll find a removable rear pillion for an extra passenger and dual tailpipes mounted on the left side, swappable for a titanium Akrapovic exhaust - just one of many customization options BMW Motorrad is offering for the R nineT.
