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.

National Corvette Museum to recreate sinkhole experience for patrons [UPDATE]

UPDATE: The Thunderdome at the National Corvette Museum is not a ride; instead it's an experience that mixes digital graphics and thundering sound. For a brief period, it looked like the National Corvette Museum was going to preserve that sinkhole that ate eight important 'Vettes last year. After all, tourism boomed there afterwards. However, keeping the crater would have been more expensive than just doing the repairs. The museum isn't ready to let people completely forget, though, and now intends to make a major attraction out of a recreated version of the calamity. The museum's plan turns the sinkhole disaster into an amusement park ride called the Thunderdome, according to GM Authority. In a smaller recreation of the Skydome, 15 people at a time would get to watch an imitation of the sinkhole devouring the eight Corvettes. To make the experience even more immersive, visitors would get to view this all from an artificial, underground cave. If you missed seeing the actual pit, this would certainly be a bizarre way to experience it. According to GM Authority, the exhibit would also include an explanation of how sinkholes occur. The Corvette museum reportedly wants the attraction open by this fall.

GM again delays plant that will build the Silverado EV

  General Motors Co. will again push back the planned opening of an electric pickup truck plant in suburban Detroit and has delayed a Buick plug-in amid uncertain growth in battery-powered car sales. Mary Barra, the company’s chief executive officer, told analysts Tuesday on an earnings conference call the automaker is postponing until mid-2026 the opening of its Orion Assembly factory, which will make the Chevrolet Silverado EV. This is the second delay for the plant, which was originally slated to start production in late 2024. Shares of the automaker fell 4.1% to $47.52 as of 9:39 a.m. in New York. The stock is up about 32% so far this year. The delay is a main reason why GM wonÂ’t be able to meet its previous goal of having production in place to make 1 million EVs by the end of next year. The company said they will add production as buyers show more interest in electric vehicles. “We continue to make sure we continue to scale the business to customers and where they are at,” GM Chief Financial Officer Paul Jacobson said on a call with reporters. GM reported on Tuesday a 60% jump in second quarter profit compared with a year ago, topping Wall StreetÂ’s expectations on strong demand for its traditional gas-powered trucks in the US market.
