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.

BMW M4 Concept bows, takes handoff from M3 Coupe

Remember how, when the first BMW M4 Concept images leaked earlier today, we told you the official information would be coming later this evening? Well, scratch that. The whole kit and caboodle is now online, meaning all the official details are below, as well as a full gallery of high-res images above.
The replacement for the M3 Coupe, the Concept M4 Coupe shares a number of styling similarities with its dearly departed forbearer. To us, it's kind of like a mishmash of greatest hits from the new 4 Series and the old M3. The 4 Series headlights have grown on us, and the side grilles, which are part of BMW's Air Curtain and Air Breather system, are functional.
The power dome in the hood is smaller than on the M3, but is of a similar shape, while the rear diffuser and exhaust treatment look like they're lifted straight from the old car, aside from being finished in carbon fiber. Speaking of which, the carbon fiber roof sports a new touch, a cool BMW M tri-color that runs the length of the roof on the driver's side. The 20-inch M alloy wheels come in a twin five-spoke design, which has sort of become a calling card of BMW's M cars in recent years. Hiding behind those meaty wheels are M's carbon-ceramic brakes.

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.)
