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.

Hertz goes Dutch with Ford Focus ST-H

Want to take a performance car for a ride? Hertz can make that happen. Spin by your local rental location (depending, of course, on availability) and you can take out a Dodge Challenger, Ford Mustang, Chevy Camaro, even a Corvette as part of the Adrenaline Collection. Hertz's Dream Cars lineup even includes Porsches and AMGs. But the really interesting stuff is what you can't get anywhere else: cars built specifically for Hertz.
Back in 1966, Hertz had Ford cook up a special run of Mustang GT350H models in back with gold stripes. It became an icon in and of itself, and in 2008 Hertz had a new batch of Shelby GT-Hs made. Earlier this year, Hertz contracted Penske to deliver another fleet of specially-built Mustangs you can rent. But if your travel plans include a trip to the Netherlands, Hertz has a completely different type of specially-prepared Ford on offer for you.
Back in August, Ford delivered a couple of Focus STs made specifically for Hertz in Holland. Now it's expanded that fleet even further. The Ford Focus ST-H features the same 252-horsepower 2.0-liter turbo four (and everything else) as the standard Focus ST, but gets that signature black exterior with gold stripes and a black leather interior with Recaro buckets. So in case a trip to Amsterdam doesn't hold enough thrills, now you can throw a hot hatch into the mix as well. Scope out the press release (in Dutch - isn't that weird?) below.
