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.)

2014 BMW X5 doesn't upset the formula

BMW has unveiled the 2014 X5, and fans of the company's CUV will find plenty familiar in the machine. The biggest change to the recipe comes in the form of the X5 sDrive35i, which is the first rear-wheel drive version of the high-riding five-door to date. Buyers will, of course, continue to be able to opt for all-wheel drive, and both models will get their thrust from a 3.0-liter, turbocharged inline six-cylinder engine. That powerplant makes 300 horsepower and 300 pound-feet of torque and is mated to an eight-speed automatic transmission. BMW says the combination is good enough to get the SUV to 60 miles per hour in around 6.2 seconds.
Those who require more thrust can step up to the more potent X5 xDrive50i with its twin-turbo 4.4-liter V8 engine. Drivers get to enjoy an extra 45 hp over the previous model, with final output up to 445 hp and 480 lb-ft of torque. Paired with an eight-speed automatic of its own, the engine can hustle the big X5 to 60 mph in 4.9 seconds.
The 2014 BMW xDrive35d continues to offer diesel power, though output has dropped 10 horsepower to 255 hp and 413 lb-ft of torque. Even so, BMW says the X5 diesel will be just as quick or quicker than the 2013 model. You can check out the full press release below for more information.

The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed

The BMW specialists at Alpina know how to exploit a niche when they see one. With the BMW M4 still not technically official, it saw the need for a higher performance four-seat convertible than the 435i 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the Geneva Motor Show.
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).
