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 M4 spied in coupe and convertible form

From the sound of it, we'll have to wait until the Detroit Auto Show to see the production version of the BMW M4, but spy shots show the new hi-po BMW testing recently in both coupe and convertible form. Showing a lot more skin than recent spy shots, these M4 prototypes look very similar to the M4 Concept we saw at Pebble Beach.
Carryovers from the concept car include the funky mirrors, bulging hood and the slotted front fascia vents, but the rear fascia seems to be missing the added flair of the concept and, as expected, the carbon fiber front splitter and exhaust tips are also missing from these M4s. Like the current M3 Convertible, the drop-top version of the M4 will utilize a retractable hard top.

BMW i8 customized by AC Schnitzer [w/video]

It may not enjoy the kind of factory support that Alpina does (let alone Munich's own M division), but as far as independent BMW tuners go, few have the kind of clout that AC Schnitzer does. Heck, it even won the DTM championship for BMW in its first year back in the series. And now the legendary Bimmer tuner has turned its attention to the i8. The list of Schnitzer's enhancements for the plug-in hybrid sports car is long, but perhaps wisely shies away from messing with the intricate powertrain. Instead the customization options focus on elements like the suspension, rolling stock, aero kit, and interior. AC Schnitzer has dropped the ride height by almost an inch at the front and 0.78 inches at the rear. It's fitted a set of 21-inch forged alloys with five split spokes and low-profile rubber to trim nearly ten pounds off the vehicle's unsprung weight while increasing its contact patch for better grip (albeit likely with higher rolling resistance). There's also a comprehensive rolling kit made of carbon fiber, including front spoiler elements, side skirts, and a rear wing that to our eye looks a little out of place on the i8, though individual customers may disagree. And the interior has been upgraded with aluminum pedals and velour floor mats. Of course customers will be able to pick and choose which elements they'd want to install on their hybrid vehicles, but you can check out the fully spec'd demonstrator in the high-resolution image gallery above and in the video below. (You just may want to turn down your speakers if you're not into German techno-pop.) Revolutionary Sporting Performance and Innovative Design The i8 by AC Schnitzer emphasises the strengths of the plug-in hybrid from Munich The BMW i8 is revolutionising its vehicle class as the first sports car to have the fuel consumption and emission values of a small car. Now thanks to AC Schnitzer, this revolution is being followed by another: the AC Schnitzer special equipment for the BMW i8 emphasises even more clearly the sporting performance and innovative design of the powerful, environmentally-friendly coupe. Lowered by 25 mm at the front and 20 mm at the rear, the i8 by AC Schnitzer hugs the tarmac more closely than the standard vehicle and can therefore develop maximum efficiency and dynamics on the road.
