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.

Ford adding stop-start to all major model lines

Ford has gone all-in on its efforts to offer most of its new vehicles with a fuel-efficient EcoBoost engine, but the automaker is reportedly preparing to take another big step toward improving vehicle efficiency. Automotive News is reporting that Ford will soon expand the availability of start-stop technology, which was first offered - presumably the first non-hybrid vehicle, that is - on the 2013 Fusion (equipped with the 1.6-liter EcoBoost engine) as a $295 option.
The benefit of start-stop is reduced fuel consumption as it shuts the engine off at long stops, and AN quotes Ford as saying that drivers can save more than $1,000 on fuel costs over five years. Despite this, the option hasn't been popular on the Fusion thus far, but it could be more beneficial on bigger vehicles like the F-150. Ford also said that the next-gen Edge, which was previewed in concept form at the LA Auto Show, will be equipped with auto start-stop to help make the EcoBoost engines even more efficient.

Watch these Australian Ford and Holden muscle cars duke it out

Australia's Motoring has put together a little video on two of the great performance vehicles available down under - the Holden VF Commodore HSV GTS and the Ford Falcon FPV GT R-Spec. And while both FPV and the Falcon might be on their way out, there's still plenty of time for a little head-to-head comparison between the two.
The cars aren't all that well evenly matched, though. The Ford boasts a 5.0-liter, supercharged V8, which the Aussies measure out at 449 horsepower and 420 pound-feet of torque. The HSV, though, with its Corvette-derived, 6.2-liter, supercharged V8 is just too powerful - 576 hp and 545 lb-ft of torque.
Predictably, it doesn't end too well for the Ford. As the guys from Motoring point out, the new VF Commodore is just too new and too good, with its extra power and its adaptive dampers (GM's excellent MagnaRide). Interestingly, Motoring did point out that the Holden's electric steering is better than the Ford's hydraulic steering, which is a lot like a Porsche purist saying they prefer water-cooled engines to air cooled.
