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 i8 headed to Frankfurt

According to Edmunds, BMW will reveal its production i8 hybrid sports car at the Frankfurt Motor Show next month. The i8 is the second vehicle to come from the automaker's new "i" initiative, following the debut of the smaller i3 hatchback last month.
The BMW i8 makes its debut nearly four years after the original Vision EfficientDynamics concept bowed at the Frankfurt expo in 2009. The production car is expected to use a 1.5-liter three-cylinder engine that drives the rear wheels, coupled to an electric motor that drives the front wheels. Combined output is said to be something like 393 horsepower and 406 pound-feet of torque, based on our earlier reports. The i8 is also expected to be very light, with curb weight coming in somewhere around 3,125 pounds. Finally, the i8 is said to have a pure electric range of 20 miles, and should be able to hit 62 miles per hour in just under five seconds.
Other publications had the chance to ride along in the i8 (in prototype form) and came away impressed. We're hoping we'll feel the same when the car officially goes on sale sometime in early 2014. Stay tuned for more at the i8's official unveiling in just a few weeks.

BMW Vision Gran Turismo takes M235i Racing to the virtual extreme [w/videos]

Late last year, Mercedes-AMG worked up a concept car called the Vision Gran Turismo. It presented it at the Los Angeles Auto Show, but that wasn't the point: the point was that it would feature in Gran Turismo 6 on the PlayStation 3. It wasn't the first concept created specifically for the popular driving simulator - following similar projects by Citroën and Red Bull Racing - and as we reported just a month later, it wouldn't be the last. What we have here is the next.
Looking like an even more extreme version of the M235i Racing, the BMW Vision Gran Turismo concept builds on "the tradition of the successful BMW touring cars of the 1970s" in a heart-pumping, if unfortunately strictly virtual form. It's got more extreme aero than the aforementioned M235i Racing and a striking take on the M division's signature light blue, dark blue and red stripe over white livery.
Underneath the digital bonnet sits the same 3.0-liter inline six as the M235i, but pumping out a prodigious (if theoretical) 549 horsepower - far more than the 333 hp in the actual Racing version or the 320 hp in the roadgoing model. Of course BMW has given it an ideal 50:50 front-rear weight distribution and a curb weight of 2,600 lbs - nearly a thousand pounds less than the roadgoing M235i.
