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.

2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

Ring Taxi BMW M3 chases an Aventador SV and Cayman GT4

On paper, a BMW M3 that's loaded with three passengers probably shouldn't have a chance at keeping up around a track with a Porsche Cayman GT4 and a Lamborghini Aventador LP 750-4 Superveloce. In the real world, driver skill and track knowledge can make all the difference, though. And when the M3 is a Nurburgring Taxi with a driver that knows the course incredibly well, we end up getting a fantastic lap like this one. The 'Ring Taxi driver starts by teasing his passengers that they'll see whether the Lambo is fast. Before the two of them get on track, the GT4 cuts in to join the party. What follows is a fascinating lap of the Nordschleife. It's impressive how the BMW driver's skill allows him to keep up with the two other cars and blow past tons of other traffic. During faster sections, the Porsche and Aventador start to pull away, but as soon as the course gets curvy again, the M3 is right back in the action. As the group pulls back into the parking lot, even the Ring Taxi driver sounds impressed with his performance. See the impressive show in the video above. Related Video:
