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.

Techstars Mobility brings transportation startups to Detroit

A new tech incubator is looking to combine the Motor City's automotive history with its evolving tech startup landscape. "Techstars Mobility, Driven by Detroit" kicks off its first round with 10 startups next week. Techstars is an established accelerator network with incubators around the world, and Detroit is a new addition. The projects center around mobility in some form, be it improving vehicles, moving goods, or working cars into the sharing economy in new ways. In return for a percentage stake in each company, Techstars provides mentorship, access to experts, seed money, and a collaborative environment. One startup we're particularly excited about is Motoroso. This site is like Pinterest for the car-obsessed, with boards replaced by garages that can contain photos and links to other projects. The site lets you follow brands – Chevy, Porsche, Ducati, and others already have profiles – as well as other users. For the Autoblog editors, Motoroso provides a new way to share stories, photos, and video, as well as a way to discover new products and interesting DIY projects. Take a look at the Autoblog profile and wander around the site to check things out. Another one of the startups, Classics & Exotics, is helping owners of interesting cars and would-be drivers connect in an Airbnb-style distributed rental program. Think of it as an auction catalog you can drive. Renters can specify the price, mileage, minimum driver age, and availability. Similar to Airbnb, Classics & Exotics provides each vehicle owner with $1 million in liability and damage protection. The company also vets renters for added peace of mind. Sounds like fun, and a cheap way to avoid a costly Craigslist or eBay mistake. Along similar shared-economy lines comes SPLT, a ride-sharing platform that finds people going where you're going and lets you hop in a car and split the costs. It's aimed at commuters but also has great applications for those looking for occasional one-way rides somewhere. SPLT notes that the system is a good way to meet new people – hopefully, good new people. Depending on how well SPLT keeps sketchy rides and riders out of the system, this could be a solid alternative to services like Uber and Lyft. This Techstars Mobility class has backing from corporate sponsors, including Ford, Honda, Magna, Dana, Verizon Telematics (Verizon has an offer pending to buy AOL, our parent company), and McDonald's.

Tanner Foust gets eponymous hotted-up Ford Focus ST from Cobb Tuning

Racer and Top Gear USA host Tanner Foust has partnered up with Cobb Tuning to create a special-edition Ford Focus ST. The limited-edition hatches will come packing a reflashed ECU, special intercooler, tweaked intake and freer-flowing exhaust for up to 20 percent more power than the stock creation. Cobb says that the changes should push the final dyno figure to above 300 horsepower. Buyers can also expect to find special carbon fiber aerodynamic bits on board along with a new grille, graphics and wheels. Cobb hasn't released pricing on this Tanner Foust Edition Ford Focus ST as of yet, but you can bet the whole kit won't be cheap.
Fortunately, the company will sell you bits and pieces from the overall package for your Ford, and word has it engineers are also whipping up a Foust Fiesta ST. Look for Cobb's Focus ST website to go live next month, complete with accurate specs and pricing. Until then, enjoy clicking through the gallery here.
