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 predicts 2 Series Active Tourer will have 75% conquest rate

In the last few years, BMW has definitively proven that it wasn't a slave to its legacy. In the US, the 3 Series was generally associated with smooth, flat-six engines, but the Bavarian brand dropped a four-cylinder turbo into it. The company was also known for its sports sedans, and it went green with the i3 and i8. Now, rear-wheel drive is off the table as defining its vehicles, as well. With the imminent launch of the 2 Series Active Tourer, the Bavarian's models are going front drive and opening up themselves to a whole new group of customers, so the thinking goes.
"We are expecting the Active Tourer will have a conquest rate of around 75 percent," said Frank Niederlaender, a BMW product manger, to Automotive News Europe. If you're not hip to the lingo, that means three quarters of the hatchback's buyers would come from other brands - an impressive figure, if accurate.
When it hits the road, the 2 Series Active Tourer will be the first BMW-branded vehicle to use the company's UKL front-wheel drive platform, already on the current Mini Cooper. The roomy hatchback is aimed at young families looking for a car that is luxurious but can still tote around the tots. It launches in Europe in September to compete against similar models like the Mercedes-Benz B-Class, but the Bimmer isn't crossing the Atlantic to the US until early 2015, according to ANE.

2013 Nissan GT-R and 2013 Alpina B6 mix it up on track and street

Here we have Autocar making an unforeseen comparison: the Nissan GT-R against the Alpina B6 at Brands Hatch and on public roads. Steve Sutcliffe clobbers the circuit in the 3,828-pound, all-wheel-drive sports car, then sees how well the 4,114-pound, rear-wheel drive grand tourer does against it.
Sutcliffe says there are quite a few similarities between the two cars, but that's really only on the spec sheet. The Nissan's got two turbos attached to its 3.8-liter V6, 542 horsepower and 465 pound-feet of torque. The Alpina's got two turbos attached to its 4.4-liter V8, 532 hp and 528 lb-ft. But one's brief is to be a monster on the track, the other on the boulevard, and if there's anything the video demonstrates, it's each car's focus.
