BMW dishes on 'lightweight' 2014 M4

BMW's M cars are not what we'd call featherweights. Sure, the big, bruising twin-turbocharged V8s deliver a lot of power, but the fact of the matter is that more weight often equates to less fun.
Which is why we're so excited over a recent sit-down the blokes at Top Gear had with BMW's product manager for small and medium cars, Matt Collins. The chat led to talk of the M3 Coupe replacing M4. Collins confirmed that, yes, the new M4 would be turbocharged. The new engine will also be a six-cylinder, which should make purists happy.
"What we'd like is more focus on lightweight engineering." -Matt Collins

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.)

This is the final BMW M3 Coupe

Pour some out for the BMW M3 Coupe, folks. Production of the two-door, fixed-roof M3 has officially ended, and the orange car you see here is the very last one.
But we don't just meant the last M3 Coupe of this generation - this is the last M3 Coupe ever, since the next-gen car will launch under the name M4, staying true to BMW's revised nomenclature where coupes and convertibles will use even numbers. (Don't forget, the new 3 Series coupe becomes the 4 Series for the 2014 model year.) There will, of course, be a new M3, but that badge will only be found on the four-door version.
BMW first launched the M3 Coupe in 1986, and since then, more than 40,000 examples have been built. Sedan and convertible versions were added later in the car's life, and BMW says that the current 2013 model year convertible will remain in production until September of this year.
