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.

2020 Chevy Corvette Stingray vs the world: How it compares on paper

The 2020 Chevy Corvette Stingray in its base form offers an astonishing amount of performance for the money. In fact, so impressive is the car's spec sheet that the Corvette kind of exists in two different competitive sets: one of cars priced similarly, and another with cars of similar performance and reputation. To get a feel for how it handles each of these segments, we've compiled specifications for those two sets of players. You can find the first set below, which looks at cars of roughly the same price point. Following that is a bit of analysis, and then there's a chart of cars with similar performance and reputation. And that chart will also have some analysis. Though final pricing for the Corvette hasn't been announced yet, we know the Corvette will start at less than $60,000. And as far as pricing goes, its closest competitor is the Porsche 718 Cayman, which also starts at just under $60,000. Both are mid-engined and rear-drive, but the Corvette offers an extra 195 horsepower and 190 pound-feet of torque. The Cayman does boast a curb weight of right around 3,000 pounds, so it weighs a few hundred pounds less than the Corvette, but it's likely not enough to make up for the power deficit. The Corvette's sub-3.0-second 0-60 time bears this out against the Cayman's best 4.5-second run. Impressively, though, the Cayman has more cargo space than the Corvette in a package that's nearly 10 inches shorter. The Cayman also still offers a manual option for those that prefer self-shifting. The 2020 Toyota Supra is on the cheap end of this sports car class, just crossing $50,000. It also boasts more power than the Cayman, though it's still down by 160 ponies and 105 pound-feet of torque to the C8. It's also about as roomy as the Corvette, despite being about the same size as the Cayman. Cargo space is a bit tighter. Its driving characteristics will likely differ, too as the Supra sits on a front-engine platform. It might even feel closer to a C7 Corvette in some ways. The other mid-engine entry in this price range is the 2019 Alfa Romeo 4C Spider. Its small 1.7-liter turbo inline-4 only makes 237 horsepower and 258 pound-feet of torque, but it's also far and away the lightest of this group at 2,487 pounds. That's roughly 1,000 pounds lighter than the Corvette. It isn't as fast as the Corvette in a straight line, but that lightness surely pays dividends in cornering and braking.

Recharge Wrap-up: Phoenix Cars delivers ZEUS to Navy, Volt saves gas compared to i-MiEV

Phoenix Cars has delivered its first Zero Emissions Utility Shuttle (ZEUS) flatbed truck to the US Navy. The electric flatbed will be used to transport maintenance materials around Naval Base Ventura County Port Hueneme. The Phoenix ZEUS features a 100-mile range, and can charge in just three hours. It also features vehicle-to-grid technology and direct power capability, allowing it to function as a mobile power station. ZEUS customers enjoy an eight-year/300,000-mile battery warranty and round-the-clock technical support from Phoenix. Phoenix launched an electric passenger shuttle last year, and years ago worked on an electric sport utility truck before shifting over to larger vehicles. Read more in the press release from Phoenix Cars. A man found that he used less gas by trading in his Mitsubishi i-MiEV for a Chevrolet Volt. Ben Rich saved fuel in part by using his Volt for road trips rather than needing to rent cars. Rich also found other benefits to driving a Volt, including more comfort, more freedom of movement and less range anxiety. Rich often had to turn off the heat in the winter to eke out precious miles in the Mitsubishi, which he needn't do in the Chevy, though he did have a gripe about the Volt using the gas motor to warm the car.

ChargePoint has tallied over 9 million charging sessions for a total of 65 gigawatt hours of energy. Based on national efficiency averages of three miles per kWh and 23.9 miles per gallon, this has saved 8.2 million gallons of gasoline and 60 million pounds of CO2. This accounts for what ChargePoint calls a "huge environmental impact." Read more in the release from ChargePoint below. The Environmental Impact of ChargePoint Drivers Campbell, Calif.– We all know electric vehicles (EV) have enormous environmental advantages over gas vehicles. Plug-in EVs reduce carbon-based greenhouse gases, improve air quality and reduce our dependence on fossil fuels. EV drivers on the ChargePoint network have had a huge environmental impact. With over 9 million charging sessions delivering 65 gigawatt hours of energy, EV drivers have avoided over 60 million pounds of CO2 and 8.2 million gallons of gasoline, and driven over 196 million gas-free miles. *Based on national averages: EV efficiency of 3 miles per kWh, gas efficiency of 23.9 mpg and a net savings of 0.924 pounds of CO2 per kWh.
