BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

Next BMW 7 Series interior spotted

The next BMW 7 Series looks to be leading a rather dramatic change of the company's interior styling, judging by this new series of spy photos. In the trio of shots, we can see that the next 7 Series will replace the high-quality plastic buttons of the brand's iDrive, HVAC and secondary audio controls with some very, very pretty aluminum pieces. We can also see what looks like haptic touch controls for some of the HVAC systems. While the 7 Series interior has never been bad, it's lagged notably behind the Audi A8 and new Mercedes-Benz S-Class. This brightwork should be taken as a good sign, then, that BMW is preparing to take the fight to its countrymen. Aside from the handsome new switchgear, the large, wide nav screen looks like a pop-up unit, while it appears to be running a new version of the company's infotainment system. These spy photos also give us our most detailed look at the 7 Series' new laser headlights. According to our spies, these will be an optional extra, while LED headlights will be standard. The high-output lights will flank a wider pair of kidney grilles that our spies claim will give the 7 a sportier look. Changes in back are still camouflaged, although our shooters claim the new lamps will be more angular than the current car's. Expect the next 7 Series to make its debut in the second half of 2015, which could indicate a debut at the Frankfurt Motor Show.

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.)
