2016 BMW M4 GTS: More power, less weight, ready for the track

BMW calls its new M4 GTS the "most agile, radical, and powerful M4 ever." It's got 493 horsepower, a slick new water injection system, a three-way adjustable coilover suspension, and a weight reduction of roughly 200 pounds compared to a stock M4. Only 700 will be built, with 300 allocated for the United States. And did we mention it looks absolutely killer? Let's talk about that water injection system for a moment, because it's the first time this technology is being used on [an intercooled - Ed.] production road car. Basically, water absorbs heat from surrounding air, so a fine mist is sprayed into the intake manifold where it evaporates, lowering the temperature of the intake air. BMW says this reduces final compression temperature, allowing the turbochargers to operate with increased boost pressure and better spark timing. The end result is increased output – 493 horsepower and 442 pound-feet of torque from the same twin-turbo, 3.0-liter straight-six as the standard M4. That's an increase of 68 hp and 36 lb-ft. But the GTS isn't just about increased power. In fact, the bigger story is its weight reduction. BMW incorporated the use of aluminum and carbon fiber throughout the M4's construction, and DIN curb weight is listed as 3,329 pounds. It's unclear if that's the exact US measurement, and BMW couldn't comment on that as of this writing, but compared to our 3,530-pound stock M4, that represents some 200 fewer pounds of heft. Carbon fiber reinforced plastic (CFRP) is used in the hood, making that part some 25 percent lighter than the stock piece. CFRP is also used for the driveshaft, making it 40-percent lighter than the standard setup. Even inside the car, the new center console is 30-percent lighter than what you'd find in a normal M4. The rear seats are gone, and we're sorry to say that the cool racing buckets pictured here won't be available in the US. Making this thing super capable at the track is a three-way M coilover suspension, combined with upgraded carbon ceramic brakes, set behind staggered wheels and tires. Up front, the GTS rides on 19-inch rollers wrapped in 265/35-series Michelin Pilot Sport Cup 2 tires, and out back, 20-inch wheels are fitted inside 285/30-series rubber. The only transmission available is the seven-speed, M DCT dual-clutch unit, and when all is said in done, BMW says the M4 GTS will run the infamous Nurburgring Nordschleife in 7 minutes and 28 seconds. Another cool feature: organic LED technology.

These BMW M6 GTLM racing liveries are great

This weekend we'll see a whole new crop of racing machinery line up for the start of the 24 Hours of Daytona, including the new BMW M6 GTLM. So far we've only seen it in flat black, but now the Bavarian automaker has revealed two special liveries for the two cars it will be fielding in the race this weekend. The number 25 car features a throwback livery that reinterprets BMW's classic racing stripes of red, dark blue, and light blue over white bodywork. It's designed to be reminiscent of – and even features images of – legendary racing machinery from the Roundel marque's history. Those include the 3.0 CSL that wore the same number when it took the company's first win in the US at Sebring in 1975, the M1 sports car from the early 1980s, the V12 LMR that scored BMW's only Le Mans victory to date in 1999, and the M3 GT that dominated the American Le Mans Series in 2011. The second car features a more futuristic livery, wearing the number 100 to mark the automaker's centenary and a multicolor lattice design applied with a luminescent 3D-effect reflective vinyl on a white body. They'll both be fielded by BMW Team RLL, a partnership between the manufacturer and Rahal Letterman Lanigan Racing (of Indy fame), which took a class win at Laguna Seca last year. The new M6 GTLM replaces the previous Z4 GTLM and will proliferate across racing grids in motorsport series around the world following its race debut this weekend. But it won't be the only new piece of racing kit turning a wheel in anger for the first time at Daytona; the new Ford GT and Ferrari 488 GTE will be competing in the GT Le Mans class alongside proven competition machinery. BMW Team RLL reveals 100th anniversary livery for the BMW M6 GTLM race cars in Daytona. Daytona (US), 27th January 2016. BMW Team RLL today revealed two commemorative 100th anniversary liveries for the new BMW M6 GTLM race cars, with which Bobby Rahal's (US) team will compete in the 24 Hours of Daytona (US). The race forms the first round of the 2016 IMSA WeatherTech SportsCar Championship (IWSC). The number 25 car sports a look reminiscent of the iconic BMW 3.0 CSL, which contested its first season of racing in North America back in 1975 and claimed the first victory in Daytona 40 years ago. The second BMW M6 GTLM will race with the number 100. To mark BMW's 100th anniversary this year, its livery looks to the future.

Behind the scenes of BMW's 'Driftmob' [w/videos]

All this, for one minute and 47 seconds of action-packed footage with no official plot.
We arrive in Cape Town, South Africa, on the third and final practice day for the drivers of a BMWStories internet video called The Epic Driftmob feat. BMW M235i. We are immediately whisked to a large, empty parking lot on the outskirts of Cape Town, where tires are squealing and chunks of rubber are flying as five red BMW M235i coupes churn up more smoke than a California wildfire. And the smell - it smells like heated metal, the kind of thing rev limiters are made for. Times five.
