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.)

BMW Shanghai: Driving in mega cities, designing the future and more

The BMW enclave is a suitable mix of high-tech and throwback cool.
A few days before the Shanghai Motor Show kicked off, we were part of an international group of media that was invited to have a look at the BMW Designworks Shanghai Studio and ConnectedDrive Lab facility. The building that BMW found to house its Chinese think tank is in a lovely part of Shanghai known as the former French Concession. The late 1890s and early 1900s French architectural style, brick-paved streets and tree-lined spaces feel a world apart from the ultra-modern heart of Shanghai, and the BMW enclave is a suitable mix of high-tech and throwback cool.

2014 BMW 4 Series Coupe officially debuts, priced from $41,425*

Well, that didn't take long. Less than two hours after the first images of the 2014 BMW 4 Series Coupe leaked onto the Internet, we've been given the go-ahead to publish the whole kit and caboodle. And while we won't say we told you so, it looks as though the car's official details are standing true to our earlier predictions.
In other words, BMW will offer the 4 Series in 428i and 435i models, both of which can be had with xDrive all-wheel drive. Just like in the 3 Series, the 428i is powered by a 2.0-liter turbocharged inline four-cylinder engine, good for 240 horsepower and 255 pound-feet of torque, and the 435i gets BMW's turbocharged 3.0-liter inline-six making 300 hp and 300 lb-ft. In three of the four models, both a six-speed manual and eight-speed automatic transmission are available; the 428i xDrive can only be had with the auto 'box. The 428i (with rear-wheel drive, we assume) can hit 60 miles per hour in 5.7 seconds (though BMW doesn't specify with which transmission), and the 435i will do that same sprint in 5.3 seconds with the manual and five seconds flat with the eight-speed auto.
We've already dissected the 4 Series' visuals, but the numbers show just how different it is from the 3 Series sedan. The 4 Coupe is one-tenth of an inch longer overall, while riding on the same 110.6-inch wheelbase, is 0.6 inches wider, and has a roofline that's a full 2.7 inches closer to the ground. It looks sleek, incorporating BMW's new design language from the 3 Series with an overall profile that's similar to the larger 6 Series coupe.
