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.

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.

Mazda Turnpike in Japan shut down for racing

The people behind Motorhead Magazine in Japan clearly have some friends in high places. Not only did they manage to shutdown eight kilometers of the Mazda Turnpike up the Hakone mountain, but they invited some of the country's premiere racers to take a drive up the hill. This wasn't just a Sunday cruise either. Featuring a BMW Z4 from the Super GT series, a classic Ford GT40, two flavors of Nissan GT-R and two takes on the Subaru Impreza WRX STI, these guys came ready to run. When an opportunity to let racecars challenge a curvy mountain road presents itself, you don't squander it. Thankfully, the folks at Motorhead knew that and outfitted the course with a plethora of cameras and high-quality sound equipment to capture the action. The result is nothing short of sublime. Take the video's urging to turn up your speakers for this one, and watch as these racers hit ludicrous speeds in a beautiful place never meant for them.
