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.)

Watch two championship-winning DTM cars from BMW go head-to-head

BMW recently had a little fun with two of the company's past DTM champions. Roberto Ravaglia and Bruno Spengler, winners of the 1989 and 2012 championships, respectively, both showed up at the world-famous Hockenheimring with their title-winning cars. The two swapped seats, with Ravaglia taking the helm of Spengler's BMW M3 DTM racer and Spengler sliding behind the wheel of Ravaglia's first-generation M3 racer in the classic BMW Bank livery, and headed for the track. Spengler got a 23 second head start in the first-gen M3 with Ravaglia chasing behind.
It didn't take long for the older hotshoe to sort out his new ride and close the gap. The short clip below follows the two as they make their way around the circuit, but the really interesting portion comes when the pair begin discussing what they like and don't like about each other's machines. You can check out the full video below for yourself.

BMW 1 Series sedan prepares to fight Mercedes CLA, Audi A3

The entry-level premium sedan segment is pretty hot right now, with the Audi A3 and Mercedes-Benz CLA-Class doing well for their respective automakers here in the US. Of course, BMW has its 2 Series, but that's currently only available as a coupe, with a convertible bodystyle forthcoming. That all looks to change, however, as our spies recently caught BMW testing a four-door 1 Series sedan that seems to have the A3 and CLA clear in its sight.
BMW's entry-level four-door is expected to ride on the same front-wheel-drive UKL platform that we recently spied in Mini Countryman form. We're pretty sure this thing will launch under the 1 Series line (odds for sedans and wagons, evens for coupes and convertibles), but it's anyone's guess with BMW - after all, the five-door, front-drive Active Tourer wears a 2 Series nameplate.
Look for the 1 Series sedan to launch sometime in 2016 as a 2017 model. Better late than never in the entry-lux segment, we suppose.
