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.

Shelby GT350R offers first mass-produced carbon fiber wheels

In the world of race engineering, reducing total weight is good, but reducing unsprung weight is flippin' fantastic. That's the reason Ford is pushing the envelope in terms of technology for the Shelby GT350R's wheels. Joining the likes of Koenigsegg in the offering, Ford has teamed with Australian outfit Carbon Revolution to produce the CF rollers en masse for the first time. Destined for the hubs of the new Shelby GT350R, the new hoops weigh just 18 pounds each, versus the 33-lbs weight of a similar aluminum wheel. On top of slashing up to 60 pounds in unsprung weight, there's such a reduction in rotational inertia – 40 percent, versus aluminum wheels – that Ford actually has to recalibrate the magnetic ride control system and springs. Thanks to, we're guessing, scenes of crashed Formula One cars disintegrating and spewing shards of carbon fiber all over the track, Ford seems quite keen to do away with the idea that CF is strong, but brittle. The company conducted extensive shock testing, ramming a wheel into a curb at speed. According to the Blue Oval, the lightweight wheel allowed the suspension to respond so quickly that the impact was "greatly diminished," causing the tester to run the experiment again, thinking there'd been a mistake. After recording brake rotor temperatures of 900 degrees Celsius (over 1,650 degrees Fahrenheit, or well past the point that aluminum or magnesium would melt) during testing, Ford and Carbon Revolution actually redesigned the wheels to "a thermal standard more suitable for motorsports," by adding an "incredibly thin, nearly diamond-hard coating that reliably shields the resin from heat." The same process was used to protect engine turbine blades on the Space Shuttle. While the work by Ford and Carbon Revolution should make GT350R customers excited, the work being done here could have serious implications for performance cars in the future. That's the real takeaway here, and is something that should leave fans of all performance vehicles excited.
