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.

Opel pulls out of Russia, GM to focus on Cadillac, 'iconic' Chevys

General Motors is going to realign its priorities in the struggling Russian marketplace, withdrawing its Opel brand and pulling out mainstream Chevrolet models. Instead, the General will take aim at Russia's well-established oligarchy, pushing Cadillac as well as "iconic" Chevrolet models, like the Corvette, Camaro and Tahoe. "This change in our business model in Russia is part of our global strategy to ensure long-term sustainability in markets where we operate," GM president Dan Ammann said in a statement. "This decision avoids significant investment into a market that has very challenging long-term prospects." Russian customers interested in an Opel or mainstream Chevys like the Spark, Aveo (the US market Sonic), Cobalt (shown above), Cruze, Orlando and the like have until December to snap up a car before the brands are pulled. "We do not have the appropriate localization level for important vehicles built in Russia and the market environment does not justify a major investment to further localize." Opel Group CEO Karl-Thomas Neumann said. GM will continue to offer service to customers in Russia. "We can assure our customers that we will continue to provide warranty, parts and services for their Chevrolet and Opel vehicles," Neumann said. Beyond realigning its brands in Russia, GM also announced that it would also be idling the company's factory in the country's second-largest city, St. Petersburg. This is the second time the St. Petersburg factory has been in the news – GM announced that it'd be idled for roughly two months back in February. Scroll down for the official press release from GM.
