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.)

AC Schnitzer's hotrod BMW 318ti remembered by MotorWeek

There are plenty of compact luxury cars available in the US today, including the Audi A3, BMW 2 Series, and Mercedes-Benz CLA-Class. In the '90s, the BMW 318ti tried to offer a similar mix of luxury at a reasonable price, but it never quite found much success in America. The 318ti looked like an E36-generation 3 Series in front but featured a stumpy liftback at the rear. The only engine available in the US was a four-cylinder. If you had the money, though, the aftermarket was ready to give you more power and more aggressive looks. AC Schnitzer dropped a bored and stroked 3.0-liter inline-six under the hood to create a pocket-sized hot rod, and MotorWeek took it for a drive. The model in this video was the promo car for AC Schnitzer's US importer, and it had every upgrade possible to show off what the German tuner's produced. Under the hood, the company installed an upgraded engine with 241 horsepower and 228 pound-feet of torque. For comparison, a US-spec M3 of the era had 240 horsepower and either 225 or 236 lb-ft, depending on the model year. AC Schnitzer also sharpened the 318ti with a suspension overhaul and short shifter. According to MotorWeek's tests, the mods got the hatchback to 60 miles per hour in 6 seconds and gave 318ti laudable handling. So much performance wasn't cheap, though. The upgrades on the promo car cost more than twice as much as the 318ti's base price. Watch this Retro Review to find out the massive amount you needed to pay to get M3 performance in a tiny package.
