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.

2016 Ford Shelby Mustang GT350R First Ride

Ford Performance Chief Engineer Jamal Hameedi was in China when he received an interesting text. Half a world away his team was shaking down the newest Shelby Mustang at Grattan Raceway in rural Michigan. The news was encouraging. The GT350R was keeping pace with a Porsche 911 GT3, even nosing ahead of it during time trials, while the GT350 was running about even with a 911 Carrera S and a Chevy Corvette Stingray. "That was a good text to get," he recounted a week later as we chatted alongside the track at Grattan. On this scorching summer day, there were no Porsches or Stingrays to be found, but we've come to preview the track-focused GT350R. Ford drivers are at the wheel, and we're riding shotgun. After several hot laps, we're left with a predictable observation: The GT350R is wicked fast and quick as hell. Much of this is thanks to the 5.2-liter flat-plane crank V8 that pumps out 526 horsepower and 429 pound-feet of torque. It's the most powerful naturally aspirated road-legal engine in Ford's 112-year history. To help the engineering process, Ford bought a Ferrari 458 Italia and ripped apart its V8. The GT350's engine ended up being 10 pounds lighter. For the coup d'grace, Ford's mill also revs to a Ferrari-like 8,250 rpm. As formidable as all of that looks on paper, it sounds even more imposing in real life (see the related video below). The engine in our GT350R crackles, growls, and opens up to a flat-out roar as we explode onto the track, gripping the door pulls to calm our nerves. Grattan is a challenging, twisty course. The corners are tight, and the elevation changes quickly. At one point, our test driver aggressively tackles a curve and we're briefly airborne. During the first stint, we reach about 140 miles per hour. But the GT350R isn't about straight-line speed or pure power. It's designed to get around a track as rapidly as possible. That means Ford took the 'base' GT350 – which should be more than at home on the track itself – and re-tuned the suspension and aerodynamics. There's a larger front splitter and rear carbon-fiber spoiler. The 19-inch carbon-fiber wheels are stiffer and lighter than comparable aluminum rollers, and they're wrapped in Michelin Pilot Sport Cup 2 high performance rubber. Additionally, Ford ripped out the back seats, air conditioning, trunk floorboard, stereo, backup camera, and anything else that wasn't necessary.

Amazon can now deliver packages to some Ford and Lincoln vehicles

Nothing succeeds without complications popping up along the way. Sure, Amazon's Prime delivery services have made shopping more convenient than brushing your teeth, but leaving millions of packages on doorsteps comes with an inherent danger: Thieves might swipe them without anybody knowing. Amazon's solution is called Amazon Key, which allows delivery men and women to enter a customer's house or car to drop off a package. This week, Ford and Lincoln announced they would be partnering with Amazon to integrate the service into some of their vehicles. Ford is following in the footsteps of Volvo and General Motors, as both companies announced their participation about a year ago. That includes Cadillac, Chevrolet, Buick, and GMC. Key will be made available for 2017-and-newer Fords equipped with FordPass Connect, and 2018-and-later Lincolns with Lincoln Connect. Key is not available everywhere, but it can be used in dozens of city throughout the U.S., and the network is expanding. To look for compatibility for your car and city, check on Amazon's dedicated Key website. Like every other tech invention these days, Key requires a smart device application, which requires a one-time setup. The service is available on the Key app or the FordPass and Lincoln Way apps. While ordering on Amazon, customers will then select in-car delivery during checkout. Input a public delivery address, and park the car within two blocks of that address. While the order is in transit, Amazon will provide status updates, another feature that takes away some of the anxiety of waiting for a package to be delivered. The package will be put into the car within a four-hour window, and users will get notifications that the exchange is complete, and the car is again securely locked. Should customers change their minds, they can always cancel the delivery method, and the car will remain locked. In that case, the delivery could go to the building where the car is parked, or be rescheduled. Ford imagines this as the beginning of numerous car-based services in the near future that can be scheduled while the owner is not there, such as car washes.
