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

Amelia Island 2013: Chevrolet Corvette Sting Ray from concepts to split windows

While this year marks 60 years of the Chevrolet Corvette, the 2013 Amelia Island Concours d'Elegance focused on one of the coupe's most sought after models, the 1963 Sting Ray. General Motors design boss Ed Welburn was on hand to show off the all-new C7 Corvette, but even the hard-edged styling of the 2014 Stingray couldn't take away from the beautiful 1963 models sitting out on the field.
In addition to the original Sting Ray and the 1959 Sting Ray Concept, some of the other classic 'Vettes included "Big Tank" racecars, an interesting cutaway coupe, a right-hand-drive Z06 and the attention-grabbing 1963 Corvette Rondine by Pininfarina. Another impressive Corvette was the 1964 Corvette XP-819 rear-engine prototype. Owner Mike Yager had the car finished as a driving chassis for this year's show, but promises the car will be back to its original glory in time for next year's event.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.
