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 announces M235i xDrive, 7 Series Exclusive among summer upgrades

Like any automaker worth its lug-nuts, BMW is constantly striving to improve its products. And so it has announced a series of upgrades for the summer - none of them revolutionary, but a couple of them notable.
For one, the Bavarian automaker has announced that is is offering xDrive traction on the M235i coupe, a model that has been available until now only in rear-drive configuration. The all-wheel drive version comes with the same 3.0-liter twin-turbo inline-six with 326 horsepower (320 in the US market) and eight-speed automatic transmission as the rear-drive version, but now channels that power to all four wheels for a 0-62 time quoted at 4.6 seconds - two little ticks quicker than the existing version. It's the first time that all-wheel drive is being offered on the 2 Series, and will also be fitted on the convertible - at least, that is, in Europe. We're waiting on confirmation of North American availability.
Among the other announcements is a special edition of BMW's flagship luxury sedan. The 7 Series Exclusive Edition upgrades with metallic paint, 19-inch V-spoke alloys, Nappa leather upholstery and a leather-trimmed instrument panel. Buyers will also be able to opt for the Merino fine grain leather and Alcantara roof lining from the BMW Individual catalog, and choose between any available engine or either wheelbase lengths.

2015 BMW M3 squares off against Alpina D3 in gas vs. diesel throwdown

There was a time when diesel meant one of two things: This vehicle's owner either wants to save some money at the pump or needs to haul massive loads. It definitely did not mean that the owner of said machine wanted to drive fast, but that perception has slowly but surely been changing over the last several years, with automakers from Volkswagen and Ford to Audi and BMW offering spiced-up versions of their high-compression, turbocharged diesels.
It's that last automaker we mentioned that's the subject of the video you'll see down below. One bright-blue BMW M3 was procured by the Brits at Autocar, and it was lined up against a deep-black Alpina D3 (which we sadly can't buy in the US) in a spate of tests, including acceleration, stopping, sound and lap times on a closed circuit. The results, which we won't spoil for you, were enlightening, and were followed up by personal impressions from the man behind the wheel.
We know you're curious. All it takes to find out which of these 3.0-liter, twin-turbo-powered 3 Series variants came out on top is to scroll down below and watch. You know what to do.
