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 i8 customized by AC Schnitzer [w/video]

It may not enjoy the kind of factory support that Alpina does (let alone Munich's own M division), but as far as independent BMW tuners go, few have the kind of clout that AC Schnitzer does. Heck, it even won the DTM championship for BMW in its first year back in the series. And now the legendary Bimmer tuner has turned its attention to the i8. The list of Schnitzer's enhancements for the plug-in hybrid sports car is long, but perhaps wisely shies away from messing with the intricate powertrain. Instead the customization options focus on elements like the suspension, rolling stock, aero kit, and interior. AC Schnitzer has dropped the ride height by almost an inch at the front and 0.78 inches at the rear. It's fitted a set of 21-inch forged alloys with five split spokes and low-profile rubber to trim nearly ten pounds off the vehicle's unsprung weight while increasing its contact patch for better grip (albeit likely with higher rolling resistance). There's also a comprehensive rolling kit made of carbon fiber, including front spoiler elements, side skirts, and a rear wing that to our eye looks a little out of place on the i8, though individual customers may disagree. And the interior has been upgraded with aluminum pedals and velour floor mats. Of course customers will be able to pick and choose which elements they'd want to install on their hybrid vehicles, but you can check out the fully spec'd demonstrator in the high-resolution image gallery above and in the video below. (You just may want to turn down your speakers if you're not into German techno-pop.) Revolutionary Sporting Performance and Innovative Design The i8 by AC Schnitzer emphasises the strengths of the plug-in hybrid from Munich The BMW i8 is revolutionising its vehicle class as the first sports car to have the fuel consumption and emission values of a small car. Now thanks to AC Schnitzer, this revolution is being followed by another: the AC Schnitzer special equipment for the BMW i8 emphasises even more clearly the sporting performance and innovative design of the powerful, environmentally-friendly coupe. Lowered by 25 mm at the front and 20 mm at the rear, the i8 by AC Schnitzer hugs the tarmac more closely than the standard vehicle and can therefore develop maximum efficiency and dynamics on the road.

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:
