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.

2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.

2016 Chevy Volt sneak peek at CES

Here it is, folks – your first real glimpse at the 2016 Chevrolet Volt. The gasoline-electric sedan will officially debut at the Detroit Auto Show next week, but Chevy gave us a sneak peek of its redesigned Volt at a media event in Las Vegas late Sunday, as part of its CES festivities. There isn't a ton to see here, and sorry about the low quality video (and for us not standing front and center during the reveal). But we can clearly see the car's redesigned front fascia – something recently previewed at a fan event in Los Angeles. For another view, check out a high-res photo of the new Volt from our friends at The Verge, here. Chevy even tweeted a photo of the Volt's new nose on its official Volt Twitter account, which you can see below. The automaker didn't divulge any details about its new Volt, but we already know quite a bit. For starters, the Volt will use a new, 1.5-liter gasoline engine and won't require premium fuel. It'll have more EV range and a bigger battery, too. We'll have a whole mess of information when the 2016 Volt is fully revealed in Detroit in about one week's time. In the meantime, here are some more looks at the Volt, courtesy of the Twitterverse. We're so excited about #NextGenVolt we brought it out early at #CES2015!
