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.

BMW to offer carbon fiber wheels in a year or two

The Citroën SM sat on the first set of production glass fiber and resin wheels in 1972 when parent company Michelin developed the exotic hoops in order to take the SM rallying. It wasn't until 2008 that we got the first all-carbon-fiber wheel for passenger cars in the form of a prototype model from Weds Sports in Japan that remained a prototype. Australian company Carbon Revolution followed that a year later with its CR-9 all-CF wheel, first introduced on the Shelby Ultimate Aero and now available for independent purchase for about $15,000 per set. BMW could be the first OEM to offer entire wheels in carbon fiber reinforced plastic in two years.
The wheels - either all-CFRP or using a CFRP rim and alloy spokes - were shown off during BMW's Innovation Days in Munich and are products of the development work done on its i-branded cars. The full-CFRP wheel is 35-percent lighter than a forged alloy wheel, the hybrid alloy and CFRP wheel is 25-percent lighter, making for a decent drop in unsprung rotating weight. As demonstrators during a tech day the wheels aren't yet in the pipeline for production and EU approval, but an article in Auto Express claims that they could be on the market as soon as two years from now.
Other possible parts include a full carbon fiber steering wheel and propeller shaft, the latter of which is coming as a single-piece component on the new M3 and M4. BMW is also talking up its use of secondary carbon fiber - waste material from i3 and i8 production - that can be used for items like IP support structures, seat frames and spare wheels in place of traditional metals like aluminum and magnesium. There's an excerpt of the Innovation Day press release below with more details.

BMW X6 M said to lap the 'Ring in 8:20

Bimmer Today reports that the German rag Auto Zeitung ran an Audi RS3 and a BMW X6 M around the Nurburgring together, and the hotted-up sports activity vehicle came in just five seconds behind the white-hot hatch. Driven by 'Ring regular Horst von Saurma, the RS3 ran its lap in 8 minutes, 15 seconds, and the X6 M ran an 8:20. If those times are accurate, that makes the X6 M the second fastest production SUV on the lap-time list according to Wikipedia: ahead of it is the 550-hp Range Rover Sport SVR, which ran a time of 8:14. That time puts BMW's 575-horsepower, 5,200-pound SUV four seconds ahead of the time registered by the last-gen, 555-hp X6 M, and well ahead of the Porsche Cayenne Turbo S that Sport Auto clocked an 8:34 with. It would not, however, match the predictions that X6 M project manager Herbert Bayerl made for it in an interview with Sport Auto earlier this year. Bayerl said "The new BMW X6 M moves at the level of M3," speaking of the E92 BMW M3 that Sport Auto ran around the 'Ring in 8:05. It is, though, two seconds faster than the E46 M3, which lapped in 8:22. Bayerl called out the Range Rover Sport SVR directly, saying, "We have been traveling much faster in testing and have undercut the time of Range Rover several times," and "We don't need any special attachments to go faster." Auto Zeitung's report on the lap is only for subscribers so we'll have to wait for more official news. For the apples-to-apples comparison we'll be looking forward to Sport Auto's hot lap, then we'll know if the Range Rover has anything to fear. Related Video:
