BMW celebrates with M4 DTM Champion Edition

Go back just a few seasons, and Germany's DTM touring car series was a straight-up competition between Audi and Mercedes-Benz. But BMW rejoined the race in 2012, winning both the drivers' and constructors' titles on its first year back and celebrating with a special matte-black M3 DTM Champion Edition. Last season, it won the constructors' championship but not the drivers', and this year it did the opposite. In short, it's been an impressive comeback for the Bavarian automaker, and to celebrate this year's accomplishments, it's followed up with the new M4 DTM Champion Edition for Europe you see here.
Based on the new M4 coupe - which forms the basis for BMW's DTM challenger as well as its pace car - the Champion Edition is distinguished by its special livery: The orange grille frame, the matte black hood and trunk with multicolored stripes, the black stripes along its shoulder and rocker panel, and the blacked-out 19-inch wheels all to pay homage to champion Marco Wittmann's racecar, as does special lettering on the rear windows.
Other enhancements include black front splitter and skirts, carbon front flaps and mirror caps, rear spoiler and carbon diffuser, while autographed sill plates and carbon interior trim with the car's serial number adorn the cabin. Only 23 examples will be offered, symbolic of the number adorning the winning tin-top racer and the flank of this special edition as well.

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.

Porsche 911 Turbo and Nissan GT-R Nismo star in World's Greatest Drag Race 4

We love Motor Trend's annual World's Greatest Drag Race video. Now back for its fourth appearance, the idea of lining some of the world's fastest cars up for a ten-wide, straight-line, full-throttle run is, well... it's pretty freaking badass.
The lineup this year boasts some impressively fast cars to be sure. The group of ten includes the following darlings: Alfa Romeo 4C, BMW i8, BMW M4, Chevrolet Camaro Z/28, Ford Fiesta ST, Jaguar F-Type R Coupe, Nissan GT-R Nismo, Porsche 911 Turbo S, Subaru WRX STI and, last but not least, the Volkswagen GTI. Give us any one of those for the weekend, and we're happy to take the keys.
It must be said though, that for a publication that draws as much water as Motor Trend does, there are some big cars that we might expect to be here instead. The Lamborghini Huracán or Ferrari 458 Speciale would have added some exotic flare to the list, and the omissions of the Chevy Corvette Stingray (for the second year in a row) and the Dodge Challenger Hellcat are real head-scratchers.
