Thermal imagery of BMW M4 DTM pit stop is red hot

A pit stop is a pit stop, right? The race car pulls in, the crew changes the tires, pumps in some fuel, maybe swaps out a busted body panel or squeegees the windshield, and off it goes for another heat. Only pit stops have become the focus of news lately for a number of reasons, whether it's because of mishaps (like the ones that prompted F1 to ban mid-race refueling), new time records (due largely to said ban) or interesting new ways to film the fast-paced action.
A few weeks ago we brought you footage of an IndyCar pit stop filmed from multiple angles courtesy of Google Glass. Now BMW has released a brief clip of one of its M4 DTM racers coming in for fresh rubber, all filmed by infrared camera. Its the kind of technology BMW uses to help optimize its German touring cars for competition, and now the Bavarian outfit has released some footage for fans to enjoy.
The resulting thermal imagery gives you an idea of how hot the car runs (and where the heat is emanating from), how warm they get the fresh rubber before they get it onto the car, and what kind of temperatures the pit crew is subjected to. Look closely enough in the 25-second video below and you'll even see the heat sputtering out of the exhaust pipes as the M4 downshifts into its pit box. (Just don't try adjusting your speakers, the clip is without audio.)

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 working on X2 crossover

Like the rest of the auto industry, BMW is going wild for crossovers, and the company's North American boss is wishing for supply to sell even more vehicles in the segment. It looks like the Bavarian brand is ready to feed all of this demand because the X2 reportedly has the green light for production, according to unnamed insiders speaking to Autocar. As its name suggests in BMW parlance, the X2 would be a five-door, high-style, coupe-like CUV that would be a smaller take on the X4 and X6. While these models aren't necessarily paragons of aesthetic beauty in the brand's lineup, their development is partially subsidized by other vehicles. The X2 reportedly shares drivetrains, electrical systems, and a platform with the next-gen, front-wheel drive X1 (pictured above). Sales in the UK at least could begin as soon as the second half of 2017, according to Autocar, and an M Performance version boasting up to 300 horsepower might even join the lineup in 2018. "We're finalizing the first prototypes now," a source said to Autocar, and a concept should preview the design before release, possibly at next year's Geneva Motor Show. BMW trademarked the X2 name in 2012, and rumors have continued to arise about it since then, including a possible design sketch. Related Video:
