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.

Best-selling vehicles by state

America loves trucks. According to Edmunds, which has tracked the best-selling vehicles by state based on new vehicle registrations, 40 out of 50 U.S. states’ best-selling vehicle is a pickup. Most often, thatÂ’s the Ford F-Series, but occasional Chevy, Ram and even Toyota top the lists. Here, weÂ’ve compiled the best-selling vehicles by state, including the four runners-up for each state. Interestingly enough, only one EV shows up in a stateÂ’s top five (Tesla Model 3 in California). Read on below to see whatÂ’s most popular in your state.

Corvette racer Gavin confirms Grand Sport debut in Geneva

Need further proof that Chevrolet is trying to turn the Corvette into a truly globe-spanning sports car? Then check out this Instagram post from Corvette Racing's Oliver Gavin that shows a new Grand Sport model will debut not at Detroit, or Los Angeles, or even New York, but at Geneva. In Switzerland. That's in Europe, land of Bugatti, Porsche, Ferrari, and Aston Martin. Gavin hasn't deleted the image as of this writing, but is probably getting an earful from his Chevrolet handlers at this moment. His post shows a number of press materials, including a schedule for Chevrolet's press conference, slated for late tomorrow morning (Geneva time, of course). Gavin will be handling the introduction at the Palexpo, and he'll be joined by Corvette chief engineer Tadge Juechter, who according to the materials will be driving the new Grand Sport on stage. It's a bold move on the part of Chevrolet, showing its homespun Kentucky-built Corvette alongside debuts like the Bugatti Chiron and Aston Martin DB11. But while we now know that the Grand Sport is coming tomorrow, our next question moves on to how it will look and perform. Will Chevy revive the classic Grand Sport color scheme – a single wide, white stripe on an Admiral Blue body with two red accents on the driver's front fender – or follow the example set by the C6, which went for a subtler look with classic Cunningham-like stripes? Will there be any performance advantages over the standard model? Perhaps less weight and a smidge more power? Chevy's Geneva presser kicks off at 10:45 a.m. or 4:45 a.m. here on America's east coast. We'll be on hand both in Geneva and here at home to cover all the excitement, so check back then. And bring coffee. Related Video:
