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.)

2015 BMW 4 Series Gran Coupe might be a better 3 Series sedan

At BMW, there really is something for everyone these days. Just take a look at the massive 3 Series/4 Series range - you can have a sedan, coupe, convertible, wagon, or funky-backed Gran Turismo. And now, with the introduction of the 2015 4 Series Gran Coupe, you can have another seda... err, hatchback, actually. But perhaps, a better one.
Compared to the 3 Series sedan, the 4 Series Gran Coupe is both longer and wider by about half an inch, but is shorter in overall height by an inch and a half. Honestly, to our eyes, it looks a little better than the 3 Series, too, what with its longer roofline, more sculpted rear haunches and lower stance. Full interior volume specs for the 4GC aren't available as of this writing, but we expect them to be roughly the same as the 3 Series, perhaps with a small decrease in headroom and rear legroom. Trunk space, at 17 cubic feet, matches the 3 Series sedan, and because the 4GC actually uses a hatchback design, it should be easier to access.
Powertrains are completely carryover from the rest of the 3/4 Series range. The 428i uses BMW's well-liked 2.0-liter turbocharged inline-four with 240 horsepower and 255 pound-feet of torque, and the 435i is fitted with the company's 3.0-liter turbo-six, good for 300 hp and 300 lb-ft. An eight-speed automatic is the only transmission available in the US with either model and rear-wheel drive is standard. Only the 428i can be had with BMW's xDrive all-wheel-drive system, and interestingly, the 428i Gran Coupe is actually expected to be more fuel-efficient than its 3 Series sedan counterpart. The GC is estimated to return 23/35 miles per gallon city/highway, compared to the 23/33 mpg in the 328i sedan. The 435i Gran Coupe should achieve the same 22/32 mpg ratings as the 335i sedan.

BMW is ready for our inevitable EV future  

Is "rolling lithium" a thing, yet? Because BMW is trying to make this — the opposite of " rolling coal" — happen at this year's Los Angeles Auto Show. The Bavarian vehicular group is showing five all-new electric-powered concepts or production models in L.A. These include the C-Evolution, a 99-mile range scooter from BMW Motorcycles; the 150-mile range, two-door hardtop Electric Concept from Mini; and three vehicles from its advanced i sub-brand: the i3S, a sportier and more potent version of the brand's electric commuter nodule; the i Vision Dynamics four-door coupe concept, featuring a sporty four-second 0-60 time and a professed 373 mile range; and the long-promised roadster version of the i8 supercar, with just two seats, a bikini top, and an enhanced power pack providing 18 miles of range. The unveiling of these vehicles in Los Angeles makes perfect sense to us. California is one of the world's largest markets for luxury automobiles. It is also America's biggest market for electric-powered vehicles. Studies show that the state's combination of fiscal incentives, trendsetting cultural positioning, legislative requirements and massive population contributed to the purchase of half of the country's EVs and hybrids this decade. "The customers for the brand are mainly on the West and East Coasts, and the California customer especially is interested in sustainability and environmental protection," said Robert Irlinger, head of BMW's advanced i sub-brand. The bigger question revolves around BMW's larger EV strategy. Given the current global regulatory environment, with its rightful pressures on increasing efficiency and decreasing emissions to help soothe our warming planet and save all life on it, luxury automakers seem to be making a push toward developing a range of battery-powered vehicles to be available around or after the start of the next decade. It seems BMW, with its varied subsidiaries — from lightweight scooters to ultra-luxury barges — is uniquely poised to provide an array of such vehicles. "In the first stage of i back in 2013, we brought what you could call 'bookmark' cars to the market — the i3 commuter and i8 sports car — to show the range of what an electric vehicle could be," said Irlinger. "Now, we are seeing growing interest from customers to bring electrification to the heart of the brand, even to a sport sedan like our i Vision Dynamics four-door coupe.
