2016 Ford Focus RS shows up in Geneva, still bound for America [w/video]

Representing the super-hot hatchback movement at the 2015 Geneva Motor Show, we have the 2015 Ford Focus RS, the third-generation to wear the performance-focused designation. Bound for America for the first time, it's fair to say we're darn excited for the Focus RS and its 2.3-liter, turbocharged four-cylinder. With at least 315 horsepower under the hood and the long-awaited inclusion of an all-wheel-drive system, there's little arguing that the RS will be seriously quick off the line. It should be darn good through the bends, too. The all-wheel-drive system packs a Dynamic Torque Vectoring Control system that sends up to 70 percent of the power to the rear axle. On top of the AWD's torque vectoring ability, the Focus RS adds a brake-based torque vectoring system, which transfers power laterally, as needed. Michelin Pilot Sport Cup 2 tires should only help keep the RS glued to the tarmac. A three-pedal setup is the sole transmission option, which should delight purists. According to Ford, both the clutch and the trans itself have been bolstered to handle the 2.3-liter's power. Ford also comprehensively upgraded the looks of the Focus RS relative to the lesser Focus ST. Its enormous rear wing and the back bumper's rear diffuser complement the car's menacing face. The ST's center-exit exhaust has been ditched for a meaty set of pipes, while the car on display in Geneva shows off a different set of alloys than what we saw during the car's original debut.

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.
