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.

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.

Then it's time to talk Shanghai, where Polestar, Buick, Volkswagen, Porsche and Lincoln all had big reveals. After that, they segue to Byron's trip to Moab for the 2023 Easter Jeep Safari preview where he drove the AEV Level II Jeep Wrangler Rubicon 20th Anniversary Edition. From there, they reminisce about Mustangs in a nod to the nameplate's 59th anniversary, after which they stick to the theme with a sub-$15,000 RWD used-car discussion.

2014 Chevrolet Corvette Stingray convertible headed for Geneva debut

While most of the world is still coming down from all the hype surrounding the debut of the 2014 Chevrolet Corvette Stingray at the Detroit Auto Show earlier this month, we're already looking to the future. And according to Autoweek, the next chapter in the C7 story will unfold at the Geneva Motor Show in March. That's right, General Motors is reportedly using the Swiss stage as its venue to debut the Corvette Stingray convertible.
If this strikes you as odd, you aren't alone. After all, with a car that's such an American icon, we'd fully expect Chevrolet to unveil it here on our shores in either Chicago or New York. But according to Autoweek, GM is looking to boost export sales of its halo car, and since the C7 was engineered to compete with the world's best and brightest, showing it off in Geneva is somewhat of a smart move. What's more, those with sharp memories will recall that GM used the Geneva expo to debut the sixth-generation C6 Corvette convertible back in March 2004, so there's also a precedent.
Details surrounding the Corvette Stingray convertible are still slim, though we fully expect the 6.2-liter V8 and choice of either six-speed automatic or seven-speed manual transmissions to carry over unchanged. Prototypes spotted on the road showed the car fitted with a cloth convertible roof, as well.
