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.)

More details emerge on hotter BMW i8S coming next year

The BMW i8 recently won the Autoblog Technology of the Year award, and it's going to get even better. In October, Automobile magazine reported that BMW's i brand is working on an i8S that would be stiffer and more powerful, and celebrate the marque's centenary in 2016. At the time, one of two power unit combinations was suggested, either one of them good for more than 500 horsepower. Car magazine has added more info on the coupe said to be called Project M100, saying that in addition to being a birthday gift for BMW, it will also be a going-away statement to current chairman Norbert Reithofer, who is expected to retire in 2016 or 2017. It will also be so thoroughly reworked that there will be plenty of daylight between it and the standard i8: a more integrated carbon fiber and aluminum chassis, a wider range of materials used in the build, a larger luggage bay due to the omission of rear seats, a more aggressive suspension supporting heartier brakes and wider tires, and - perhaps - a different aero and ground-effects package to be visually different and make the most of the alterations. As for that power unit, Car says that the two options mentioned by Automobile are still under consideration, being either a 2.0-liter twin-turbo four-cylinder with 320 horsepower and a 204-hp electric motor, or a 3.0-liter straight six with 480 hp and an electric motor with 109 hp. Either choice gets an integrated starter motor good for another 27 hp, and a total torque number of roughly 520 pound-feet, 100 additional lb-ft than the current car. Word is that it will be shown for the centenary in 2016 then go on sale by the end of 2017.

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.
