Updated BMW X6 spied running the 'Ring in Germany

Following the debut of the X5 earlier this year, it shouldn't come as a shock that BMW is testing an updated X6 in its homeland. The Munich-based manufacturer trekked to the Nürburgring to test the lifted, four-door coupe it calls a Sports Activity Vehicle, while also giving us our first peak as to what the future holds for one of the weirder models in the brand's stable.
Mainly, we can safely expect the next X6 to get the same range of refinements made to its platform-mate, the X5, which debuted earlier this year. If we're lucky, that could mean an X6 sDrive35i, complete with rear-wheel drive with which to fling the big SAV about. Adding a rear-drive option could also broaden its admittedly limited appeal by lowering the cost of entry, which could serve the pricier X6 well. As a point of reference, the X5 sDrive35i is priced at $2,300 below an xDrive all-wheel-drive-equipped model.
The X6's top-flight xDrive50i model should get the same 45-horsepower bump as the X5 xDrive50i, thanks to refinements to its twin-turbocharged, 4.4-liter V8, while the 3.0-liter, turbocharged six-pot should remain unchanged. We wouldn't hold our breath for an X6 diesel to arrive, although weirder stuff has happened. Like the X5, though, this should be a pretty slim refit that improves an already competent package to go along with an expected increase in price.

Researchers halfway to cutting carbon fiber costs by 90%

Carbon fiber has been utilized for decades to build racecars, as a means to cut weight while maintaining strength. But until recently, the space-age material has been largely absent from the street on anything but supercars because of the expense to use it. Recently, BMW signaled a major shift in that trend when it starting using carbon fiber reinforced plastic panels on the i3 and i8. This relatively small scale start might be just the beginning; the German company believes that a breakthrough to inexpensively manufacture the lightweight stuff is just on the horizon.
MAI Carbon Cluster Management GmbH counts BMW, Audi, Airbus, the German government and many other organizations as supporters, and it's researching how to make carbon fiber cheaper to produce, according to Automotive News Europe. The company thinks it can reduce costs by 90 percent in the near future. "We've certainly reached a halfway point on our cost-cutting target for suitable carbon-fiber parts," said project head Klaus Drechsler to Automotive News Europe.
Unfortunately, it isn't entirely clear just what MAI Carbon is doing to make such a huge leap possible. However, a recent post on the company's website talks about a new form a carbon fiber using a thermoplastic matrix that could be cured in less than three minutes. That's compared to about 90 minutes in the traditional process with an autoclave.

BMW unleashes new M4 racer on DTM

We may not get to enjoy the fruits of it all, but we're in the midst of a golden age in touring car racing around the world. In Northern Europe, rival local series have amalgamated into the Scandinavian Touring Car Championship. In the UK, the British Touring Car Championship is enjoying the largest and most diverse grid in its long history. In Australia, the V8 Supercars series has grown from a Holden vs. Ford battle to include challengers from Mercedes, Nissan and Volvo. And in Germany, the DTM championship has managed to lure BMW back onto the grid to open up the battle between Mercedes and Audi. All good things, in short.
Since returning to the Deutsche Tourenwagen Masters in 2012, BMW has won the drivers' title once and the constructors' title twice, proving the Bavarian manufacturer to be not only a suitable challenger to the two-horse race between its star- and ring-emblazoned rivals, but the dominant force in German tin-top racing. Now BMW is set to enter its third season since returning to the DTM, and this is the car with which it intends to do so.
Replacing the M3 DTM that has impressively won half of the DTM races it has contested over the past two years, BMW's latest racing car is made in the mold of the new M4 coupe. Only it's even meaner. While the production version has switched to a turbo six, the DTM version still uses a V8: a 4.0-liter unit with four-valve cylinder heads, mandatory air restrictors and a Bosch ECU to channel 480 horsepower and 369 pound-feet of torque to the rear set of Hankook racing slicks through a six-speed sequential gearbox. The lightweight chassis is rounded out with competition-level aerodynamics and all the mandatory safety equipment.
