Next BMW 6 Series, M6 to take aim at Porsche

Since BMW reintroduced the 6 Series line back in 2003, the big two-door has happily sat as the brand's de facto grand tourer. That will allegedly change come 2017, as Car is reporting that Munich will put its coupe on a diet with the so-called G15 generation, allowing the 6 to go after the likes of Porsche. All three of the current 6's body styles will be carried over for 2017, with the base 640i Coupe trimming over 500 pounds of body fat, to around 3,450 pounds. Even the droptop is getting some lipo, dropping from 4,255 to around 3,750 pounds. It's unclear how much the Gran Coupe will be lightened, as it will be the only member of the 6 Series family that's growing in size. BMW will stretch the wheelbase of its fullsize, four-door coupe, which should make it decidedly more sedan like. The weight savings come thanks to a new modular architecture that promises a "more advanced material mix." That means carbon fiber, high-strength steel and aluminum elements, and even some titanium and magnesium bits. Along with xDrive all-wheel drive, Car is promising new six- and eight-cylinder engines, with the 640i's 3.0-liter, turbocharged gas engine producing 347 horsepower while the diesel mill turns out 333. The 4.4-liter V8 of the 650i will deliver 476 ponies, while the range-topping M6's twin-turbo V8 will reach the magical 600-hp figure. Of course, we can expect to hear more about the next 6 in the coming months and years. In the meantime, though, let us know what you think of Car's positing below, in Comments.

Takata air bag recall list

The National Highway Traffic Safety Administration confirmed yesterday that 33.8 million vehicles with Takata airbags are going to be recalled. It's the largest recall in automotive history. The already record-breaking rate of automotive recalls this year shows no signs of slowing down, especially since millions of cars with defective airbags made by global supplier Takata are under ongoing scrutiny. The federal government is warning owners that inflator mechanisms in the air bags can rupture, causing metal fragments to fly out when the bags are deployed. The faulty air bags have already been blamed for multiple deaths. How do you know if your vehicle is safe? The National Highway Traffic Safety Administration released an updated list of vehicles under recall. Sometimes however, the government's website will crash and the list may not be complete. Check your VIN at the NHTSA website to make sure. The list of cars affected by the recall has not been released, but seem to span multiple models over the years for many of the automakers.

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.)
