Chevy trademark for E-Ray may signal Corvette hybrid or EV

A spy photographer and friend of Autoblog Chris Doane spotted this trademark filing with the US Patent and Trademark Office, and there's not much to it: Chevy is calling dibs on the "Corvette E-Ray" name, and that raises more questions than answers. Being obsessed with this industry is an Autoblog core value, and Corvette is perennially a big deal. It's also historically, and famously, resistant to change. So what's going on here? Unless it's a pure show car, it's unlikely the E-Ray will be a C7-based hybrid. The current Corvette is a tightly-packaged thing, and batteries are bulky. That makes a concept of some sort all the more likely, especially with the Detroit Auto Show coming up. Unconstrained by the packaging of the real-world Stingray, this E-Ray concept may be a pure EV, or a hybrid, of any configuration. GM has built mid-engined Corvette concept cars in the past, and maybe we'll see one again in a few weeks. A gutted C7 with a pure EV drivetrain is also a remote possibility, although less likely – the Stingray wasn't engineered with that in mind, and we think GM's too big to show off a hack-job at a major auto show. Not that it is a Corvette competitor, but don't forget that the Tesla Model S P85D and it's P90D successor have taken pure EV performance into the mainstream – the upper end of the mainstream, to be sure. It has been enough to draw industry performance players into the genre. Look at Aston Martin's production-possible RapidE concept, a pure EV, and the confirmed-for-production Porsche Mission E. We've heard rumblings in the past that Corvette may become a marque unto itself, spawning a variety of variants (including the hypothesized mid-engined production car – don't hold your breath). Perhaps the gas-powered C8, in whatever form it takes, will be complemented with a greener version. We'll try to dig up insider information about what the E-Ray will reveal itself to be, but rest assured that if it shows up at Detroit we'll bring you analysis of every inch of it.Related Video: Featured Gallery 2016 Chevy Corvette Z06 C7.R Edition View 9 Photos Tip: Chris Doane/Facebook Green Rumormill Detroit Auto Show Chevrolet Electric Future Vehicles Hybrid Performance corvette stingray

The Opel GT is the concept General Motors should build for the US

Now is the time. General Motors should double-down on performance cars and build the Opel GT concept that's set to debut next week at the Geneva Motor Show. Better yet, sell it in the United States as the Chevy GT. Consumers are showing a thirst for performance cars not seen in decades. Ford has them coming in waves, with everything from the F-150 Raptor to a hotted-up Fusion. FCA US is unrepentantly building loads of Hellcats. GM should respond. The General's cupboard is hardly bare. With the Corvette, Camaro, and Cadillac's V-Series, GM has more than enough to compete with its crosstown rivals and anything Europe or Japan can throw at it. But there's also an opportunity. There's not many front-mid-engine, rear-wheel-drive, two-seat sports cars out there like the Opel GT concept. A Chevy GT that used that layout and captured some of the concept car's proportions and curves would ignite a different kind of passion in enthusiasts. It would be Miata-like. With Chevy branding, this sports car would be the everyday exotic. The concept has a turbocharged 1.0-liter three-cylinder engine, which makes about 143 horsepower to motivate a structure that weighs less than 2,200 pounds. It can hit 60 miles per hour in less than eight seconds. All of those numbers are within the front-engined Miata's territory. This new Opel is inspired by two great mid-1960s concepts that helped put its design studio, and that of its sister brand, the British Vauxhall, on the map. (The GT concept is also technically a Vauxhall, as the brands are linked in GM's European strategy.) One of them, the '66 Vauxhall XVR remained a concept. The '65 Opel Experimental GT was on the road by 1968. That shows this is doable. There's precedent. The Saturn Sky and Pontiac Solstice shared a chassis with a modern GT during that trio's brief run. If GM ever makes this concept, Opel and Vauxhall should get their versions. But Chevy is the one that could make this car a global icon. Chevrolet GT. Make it happen. News & Analysis News: The potential return of the Ford Bronco is generating a ton of attention. Analysis: That's not news, per se. But when the Bronco6G.com fan site did a rendering of a next-generation Bronco, it almost broke the Internet. Everyone from Automotive News to Jalopnik picked up the illustrations. Our own post has drawn a lot of traffic and passionate responses. People are clamoring for the Bronco's return.

GM patent reveals new two-stage turbocharger

Modern turbochargers may be some of the best ever made, but performance is something that engineers are always trying to improve. According to GM Inside News, General Motors (GM) is hoping to alleviate some of the negative aspects of a two-stage turbocharger setup with a newly-patented design. The patent, that was filed on May 19, 2016, reveals a clever bypass system that allows the engine, a four-cylinder unit, to optimize both the low-pressure and high-pressure inlets for its respective functions. According to the filing, a conventional two-stage turbocharger setup is engineered to allow both turbines to operate simultaneously at low and mid engine speeds. At high engine speeds, only the low-pressure turbine works. The setup can't isolate either the low or high pressure side, which can impair low-end performance. GM's new two-stage turbocharger setup looks to eliminate this by linking the high-pressure turbo to the exhaust manifold through the high-pressure inlet duct. The low-pressure turbo is attached to the high-pressure turbo by a low-pressure inlet duct, which is linked to a connecting channel. A single actuator that is housed in the exhaust manifold creates a bypass that can opens the high-pressure inlet or close the connecting channel. Depending on what the engine load and speed is, the ECU guides the actuator—a single rotating spindle with discs corresponding to flanges on the high and low pressure sides—to isolate one of the two turbos. Isolating the turbos allow the respective inlets to be engineered for the best possible fluid dynamic performance. The setup should increase performance and decrease lag. There's no word on what car this setup will make an appearance on, but it will most likely be used in premium vehicles before trickling down to the rest of GM's vehicles.
