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.

Road & Track names its 2013 Performance Car of the Year

Road & Track recently staged its first annual Performance Car of the Year test, pitting 13 new and updated performance cars against each other on track, then graduating the top six to a road test before picking a winner. Additionally, the magazine staff picked the best automobiles of the year in eight categories.
But first, let's cover the PCotY segment. Here's the list of cars brought to the comparison test: Audi R8 V10 Plus; BMW 435i; BMW M6 Competition Package; Chevrolet Corvette Stingray Z51; Ferrari F12 Berlinetta; Ford Fiesta ST; Jaguar F-Type V8 S; Jaguar XFR-S; Mercedes-Benz E63 AMG S-Model Wagon; Mercedes-Benz SLS AMG Black Series; Mini John Cooper Works GP; Nissan GT-R Track Edition; and Porsche Cayman S.
To find out the results of the comparison, head over to Road & Track's website or check the press release below, where you'll also find the magazine's top-rated vehicles in eight categories. Want more? Head over to the 2013 PCotY hub. But before you do that, take a stab at guessing the winner of PCotY (we'll give you one hint: it isn't a Porsche).

Chrysler called out over lackluster Ram Runner by racer who helped develop it

Fans of off-roading and desert blasting might recall that Chrysler offers an aftermarket conversion that can turn a Ram 1500 into a road-legal desert racer, called the Ram Runner. The kit, sold through Mopar, includes some significant suspension upgrades, body tweaks and a brawnier cat-back exhaust for the truck's 5.7-liter V8.
Considering all of this, comparisons with the almighty Ford F-150 SVT Raptor are common. Among the off-road community, that makes these two a sort of Chevrolet Camaro and Ford Mustang for people that prefer driving on dirt. In the Race-Dezert forum, the discussion as to which truck was better was proceeding as normal - Ram fans said their piece and Ford fans said theirs. Then, a man named Kent Kroeker offered up his two cents.
See, Kroeker is a Baja racer, and the man that helped develop the Ram Runner. Despite his association with the truck, though, he had some less than kind words for Chrysler and the Ram Runner.
