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 M boss denies supercar collaboration with McLaren

The first time there was a McLaren Honda Formula 1 team, McLaren did some moonlighting with BMW on a supercar for all time, the F1. It just so happens that McLaren Honda is a thing again, and Car magazine recently ran a piece saying McLaren and BMW would get back together on another hopped-up coupe with roughly the same working agreement as before: BMW supplies a screaming V8, McLaren builds the body to go around it. Only this time the car would be a BMW model, not a McLaren, and be BMW's version of the next-generation McLaren 650S. The Car piece said that BMW head of R&D Klaus Frolich first got in touch with McLaren nine months ago, however, the head of BMW's M division, Frank van Meel, said he doesn't know anything about it. Mentioning every BMW exec referred to in the story, van Meel told Australia's Motoring, "I haven't had a phone call, [CEO] Harald Kruger hasn't had a phone call, and Klaus Frohlich hasn't had a phone call." The Car story said the reason BMW hasn't done a conventionally powered exotic recently is that former CEO Norbert Reithofer didn't want anything to eclipse the i8, the i brand, and the eco credentials the brand is charged with promoting. Changes in the executive suite – new CEO, new M boss, new R&D chief – were thought to meant changes in approach. Not according to van Meel, who gave those same i brand reasons to Motoring as then reasons BMW has no interest in a 750-horsepower, quad-turbo coupe. On top of that, after spending billions to move the game forward with in-house carbon fiber technology, van Meel asked, "I don't understand why we would need to work with McLaren for a supercar anyway. All of the technologies the story suggested are technologies that are core competences here at BMW and at M. Nobody in the world is more advanced with carbon-fibre than we are." The extent of the denial is so detailed that we're inclined to believe BMW on this one; cover stories usually stop at curt phrases like "We have no knowledge of that" or "We don't comment on future product." So you can put away your dreams of a McLaren F1 Part Two. For now. Related Video:
