Nissan Leaf has 2nd-best sales month ever, Chevy Volt does a 2013 repeat [UPDATE]

UPDATE: The official press release says that "Volt [sales were] up 7 percent," but Randy Fox let AutoblogGreen know that this is simply due to a change in the fleet/retail mix between March 2013 and 2014. The actual number sold was exactly the same in the two months. A month ago, Nissan's director of EV sales and marketing, Toby Perry, said he expected to see the Leaf's sales momentum continue into March. It wasn't a big leap, since January and February were slow sales months in 2013 (around 640 each) before a big climb to 2,200 in March. In 2014, the first two months of the year were better (around 1,300 each) but Nissan can still be happy that the Leaf just had the best March ever and its second-highest sales month ever, with 2,507 sold. That's a 12.1 percent increase from 2013 and Perry said in a statement to AutoblogGreen that one reason is all of the buyers who are becoming evangelists for the vehicle. "We've also seen an increase in showroom traffic as we enhanced our marketing presence in March," he said. Nissan pointed to cities like Washington, DC, Raleigh-Durham, NC and urban areas in Texas as strong Leaf markets last month. On the Chevy Volt front, January and February were also slow months in 2014, down roughly half from the 2,000-ish the plug-in hybrid was selling at the end of 2013. For 2014, sales were up slightly from the first two months of the year and Chevy spokesman Randy Fox told AutoblogGreen that the March number was "pretty flat, year-over-year." Even with that warning, we were surprised to see the total come in at 1,478. Why's that? Because the total for March 2013 was ... 1,478. So, yeah, that's pretty steady even if there were 26 selling days in March period this year compared to 27 last year. As always, our more complete report of last month's green car sales will be coming soon. News Source: General Motors, Nissan Green Chevrolet GM Nissan Electric Hybrid PHEV ev sales

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.

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.
