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 recalls 200,000 vehicles for brake lights that won't turn off

Ford and the National Highway Traffic Safety Administration (NHTSA) announced a new recall for nearly 200,000 vehicles because their brake lights may not turn off. Drivers of affected vehicles equipped with automatic transmissions may also be able to shift the vehicles out of Park even when their foot is off the brake. That increases the risk of a rollaway and could cause a crash. According to documentation posted on NHTSA's recall hub, a separated brake pedal bumper is to blame for the issue. The recall applies to "certain 2014-2015 Fusion, Lincoln MKZ and 2015 Mustang vehicles originally sold or ever registered, in Texas, Louisiana, Mississippi, Alabama, Florida, Georgia, South Carolina, North Carolina, Virginia and Hawaii." The safety regulator adds that "exposure to certain environmental conditions, such as high temperatures, high humidity and salt air can cause the brake pedal bumper to disintegrate and separate from the brake pedal." Owners of affected vehicles should expect notification of the recall in early March. They will be directed to the dealership of their choice to have their brake pedal bumpers and clutch pedal bumpers replaced free of charge. Related video: This content is hosted by a third party.
