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.)

Recharge Wrap-up: Grimsel electric car breaks acceleration world record, electric Ford Raptor ATV debuts

An all-electric version of the Ford F-150 SVT Raptor is now available... as an ATV. Made by Caddyshack Golf Cars, it features officially licensed Ford badging borrowed from the super-macho pickup. It has a lifted chassis with leaf springs in the front and rear, hydraulic shocks and off-road tires. Powered by a 48-volt motor, it can do 0-25 mph in 2.9 seconds. Range is an estimated 30 miles - plenty to get you through 18 of the most rugged holes of golf you've ever played. Caddyshack also offers other miniature electric Fords, including a Shelby GT500, Shelby Cobra and 50th Anniversary Mustang. Read more at Green Car Reports. Lexus takes a crack at the BMW i3 in a new video from Funny or Die. In the decidedly anti-EV film, a group of guys drives to Las Vegas for a "dad-chelor party" in a Lexus CT 200h and a BMW i3. The Lexus hybrid makes it to Sin City without any problems, while the BMW's occupants need to make several lengthy stops to charge along the way, missing much of the fun. The video lampoons the inherent range limitations of the EV (the BMW group ends up driving slowly through the desert with no AC or radio to save energy), all in a well produced, if somewhat misguided, short comedy film. Perhaps they should have considered the i3 with a range extender? See the video below, or read more at Green Car Reports. Students from ETH Zurich and Lucerne University have set a new EV acceleration world record. Their "Grimsel" racing car was able to zoom from 0-100 kph (0-62.137 mph) in just 1.785 seconds in less than 30 meters (98.425 feet), crushing the previous record of 2.134 seconds. Even more impressive is that the Grimsel was built by the students themselves, as part of the Formula Student team at the Academic Motorsports Club Zurich. The car weighs just 370 pounds and provides 200 horsepower and 1,202 pound feet of torque from the four hub motors. The Grimsel uses traction control to manage torque for maximum acceleration. See the record acceleration run in the videos below or read more at Gizmag, at Electric Autosport or in the press release from ETH Zurich below. 'grimsel' breaks world record The 'grimsel' electric racing car today broke the previous world record for acceleration in electric cars. The vehicle accelerated from 0 to 100 km/h in 1.785 seconds in under 30 metres. The new record was set by students from ETH Zurich and Lucerne University of Applied Sciences and Arts, who also designed and built the vehicle.

2015 BMW X4 configurator is ready to get personal

The 2015 BMW X4 configurator is ready for your special touch. Starting with the 300-horsepower xDrive35i that starts at $48,925 after destination, our special touch aimed at a luxury cruiser and added $9,250 to proceedings for a final tally of $58,175. That got us the Technology, Lighting and Driver Assistance packages, navigation and enhanced USB and smartphone integration. We were tempted to go for the Dynamic Damping Control for just $1,000 and a set of 20-inch M Double Spoke Wheels, but the configurator didn't want to mix the M Sport Line with our Sparkling Brown metallic exterior hue so we skipped it.
We've covered the details on pricing and the breakdown of the order guide elsewhere, so you can always click through for refreshers. Or you can skip all those words and dive straight into trying to build an X4 that makes you say, "Yeah, now I get it."
