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 preparing new M4 GTS with water injection

Last month, BMW revealed a new safety car for the MotoGP series. Only instead of just taking one of its production models and giving it some flashing lights, special livery and emergency equipment, the Bavarian automaker used the specially equipped M4 to showcase a new water injection system. And now word has it that the tech is being worked into a new M4 GTS. The system sprays water into the combustion chamber in order to lower the temperature of the air and increase the engine's efficiency, thus allowing it to produce more power without overheating, and relying less on ambient temperatures. It does require refilling a 1.3-gallon water tank in the trunk, though. According to Car and Driver, it's that same system that BMW will be installing in the new M4 GTS, taking the place of previous M3 GTS specials. If precedent is anything to go by, the M4 GTS will also be stripped of excess weight and feature a tighter suspension, stickier tires and more, in order to make BMW's muscle coupe even more hardcore and focused for the track. We could be looking at a debut as early as Pebble Beach in August.
