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.

Autoblog's June 2019 Editors' Picks

Each year we review, test and rate hundreds of brand-new cars, trucks and SUVs. We rate these vehicles using the Autoblog score, giving a select few our Editors’ Pick. Here are the best cars we drove in June 2019. 2019 BMW 8 Series Everyone on the Autoblog staff loves a good grand tourer, so we were excited to get behind the wheel of the revived BMW 8 Series, specifically an M850i Coupe. A good GT needs to be as fast as it is stylish and comfortable, and the new 8 Series delivers. We particularly like the 523-horsepower twin-turbo 4.4-liter V8Â’s copious power and smooth ride quality, even on MichiganÂ’s pockmarked post-winter roads. We dig the interior design, too, though not everyone was in love with the exterior. ItÂ’s not the best-handling car in its class, and doesnÂ’t hide its sizable proportions very well, but itÂ’s still worth a look if youÂ’re looking for a big, fast cruiser.  2019 Ford Expedition Crossovers may be the hottest vehicles on the market, but thereÂ’s still a sizable demand for traditional body-on-frame SUVs like the Ford Expedition. These behemoths offer plenty of space in addition to truck-like capability. We like the Expedition's smooth ride, powerful twin-turbo V6 and sharp exterior design, though the interior can feel a bit cheap, especially on some of the more expensive trims. Adding options quickly puts it into Lincoln Navigator territory, and itÂ’s hard to recommend the Ford over the Lincoln when the latter packs the same capability into a far nicer package. Still, the Expedition is as good or better than the competition in most respects, and thatÂ’s why itÂ’s one of our picks. 2019 Toyota 86 Few cars at any price point are as much fun as the Toyota 86 (and its twin, the Subaru BRZ). We like the 86Â’s balanced chassis and sharp steering, and while itÂ’s not as nimble as its close rival the Mazda MX-5 Miata, the ToyotaÂ’s back seat and trunk make it a more usable vehicle. But while we like the 86Â’s driving position, the rest of the interior feels cheap and dated, especially the infotainment system. We complained about the anemic powertrain back in 2012, and itÂ’s only gotten worse as the years have gone by.

Recharge Wrap-up: Ford 1.0L EcoBoost a hit in Europe; Build a tiny inverter, win $1 million

In Europe, Ford's 1.0-liter EcoBoost engine is the best-selling turbocharged gasoline engine. The three-cylinder motor powers 20 percent of new Fords sold in Europe. Earlier this year, it won its third International Engine of the Year award, and between January and June, it was sold in about 120,000 cars. So far this year, 38 percent of Fords sold in the Netherlands, 35 percent in Denmark and 32 percent in Switzerland have been powered by the 1.0-liter EcoBoost. The engine's turbocharger spins at 248,000 rpm, and provides 24 psi of pressure. The engine produces up to 138 horsepower, depending on the version. Read more in the press release below. When lithium-ion battery packs are retired from the road, remanufacturing, repurposing, and recycling are worthwhile options, according to a study by Mineta Transportation Institute. The study included a cost-benefit analysis of those three options, and found remanufacturing to be the best route. To get the most out of them, batteries should be tested and have their damaged cells replaced then put back to use. Repurposing is the second best option, using the remaining available charge for something besides cars. Recycling on its own isn't profitable, but it could make economic sense with "increased technological breakthroughs." Learn more at Recycling International or download the report here. A smaller inverter for EVs can win you $1 million. The Little Box Challenge is an open competition to build a power inverter with a density of at least 50 watts per cubic inch. Google and the Institute of Electrical and Electronics Engineers (IEEE) are offering the hefty prize to the team that builds the inverter with the highest power density within an enclosed volume of 40 cubic inches. Teams must register by September 30. Read more at Green Car Congress or learn more at the Little Box Challenge website.
