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.

2015 Ford Edge First Drive [w/videos]

We're routinely told that it's not easy being the middle child. The oldest sibling will always outshine the rest, while the youngest is routinely doted upon. The middle child, meanwhile, is seemingly never able to measure up. You know the drill: Marcia, Marcia, Marcia! But that hasn't really been the case for Ford's mid-kid crossover, the Edge. Sandwiched between its highly successful big brother, the Explorer, and the stylish younger brother, the Escape, the Edge has had plenty of its own bragging rights over the years. It's where the Blue Oval chose to first launch MyFord Touch in 2011, and was one of the company's first applications of an EcoBoost engine in a CUV. For 2015, Ford has given the Edge a brand-new outfit, complete with stand-out sheetmetal and a revamped 2.0-liter four-cylinder engine fitted with a twin-scroll turbocharger and direct-injection. The result is a vehicle that truly stands out from its compact and fullsize siblings while promising to retain Ford's edge in the midsize CUV market. Where many of Ford's cars have opted for a slim, Aston Martin-like grille, the new Edge's face is big and bold. It's around back, however, where the Edge really comes up with its own personality. The slimmer D-pillar forms the edges of a more aggressively raked rear window. It's difficult to spot in pictures, but the result is a decidedly more assertive profile than the outgoing CUV. Beyond that, the rear is home to Fusion-inspired taillights, although unlike Ford's popular midsize sedan, they're joined together by a vehicle-spanning lighting element that prominently features a Ford badge at its center. Ford's work on the Edge's interior is less progressive, though. The owner of a 2014 model wouldn't feel the least bit out of place climbing behind the wheel of a 2015, as it features Ford's same reconfigurable instrument cluster, and a center stack that's been crowned by the latest (and final) edition of MyFord Touch. Meanwhile, more JD Power Initial Quality Study-friendly buttons have replaced the obstinate and unintuitive touch-capacitive controls. The conservative take on the interior design belies the big improvements in material quality. The leather inserts in the doors are more heavily padded and the plastics are far softer. It's a similar story throughout the cabin, where owners will notice softer dash plastics and generally richer materials.

Meet the Greenest and Meanest vehicles of 2016

If you've been keeping track, you won't be surprised with the number one entry in this year's list of greenest cars from the American Council for an Energy-Efficient Economy (ACEEE). In fact, the top three spots on the 2016 list are all the same as they were in 2015. After that, things get interesting. For one thing, this is the first Greenest list that doesn't have any purely internal combustion engine powertrain on it. Hybrids, yes, but if you want to be one of the top 12 greenest cars this year, you'd better have some sort of electric angle. ACEEE says that the conventional, gas-powered Smart Fortwo and Chevrolet Spark just missed the cut. In a statement, ACEEE lead vehicle analyst Shruti Vaidyanathan said, "The 2016 scores are in, and plug-in electric vehicles are outpacing all other vehicle offerings in terms of environmental friendliness." Like last year, one of the noticeable vehicles missing from the green list is the Tesla Model S. One reason? ACEEE takes curb weight into account (lighter is better), and the Model S is a heavy beast. The ACEEE doesn't just look at the clean side of the ledger. It also puts out a "meanest" list. These are the vehicles that pollute the most, not only from their tailpipes, but also any pollution created during the entire manufacturing process, from mining the raw materials to the energy used to produce the vehicle at the factory. The entire list, from greenest to meanest, is done using a "cradle to grave" analysis.
