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.

Sunday Drive: Spying an automotive future of performance

I spy, with my little eye ... the future of the automotive world here in the United States. That pretty much sums up this week's Sunday Drive, in which we pull out the most popular stories on Autoblog of the previous week and try to draw some sort of conclusion as to what binds them all together. This week, it's spy shots, starting with one of the biggest and baddest muscle cars the world has ever seen: the Dodge Challenger Hellcat. The Hellish coupe gets a new hood for 2019 with dual scoops, but that's about the only meaningful change for the new model year. No matter. As long as it's packing 700-plus horsepower under those two hood scoops, all will be right with the world. Moving on, we take keep the performance angle but move it from the street to the dirt with a new version of the Chevy Colorado ZR2 that we think is probably called the Bison. We think it'll keep the high-tech suspension bits of the regular ZR2, but add expedition gear that may include a snorkel and a winch. Which, if true, is pretty dang cool. Keeping the truck theme is the 2019 GMC Sierra. There's nothing particularly noteworthy about the trim level in which the truck was spied, and that's what makes this specific example interesting. Base-model trucks almost never get much attention, but they sell in droves to workers who need an honest-to-goodness truck for work or play and don't care about bells, whistles, or massive chrome badges. And finally we have the 2018 Jeep Wrangler, which is on fire on the sales floor right now. But those are all V6-powered Wranglers flying off the showroom floor. Soon, a turbocharged four-cylinder engine option will become available, and now we know that it will return up to 23 miles per gallon in the city and 25 on the highway. That makes it the most fuel efficient Wrangler that Jeep has ever sold. As always, stay tuned to Autoblog this week for all the automotive news that's fit to publish. 2019 Dodge Challenger Hellcat with twin-scoop hood spied with no camouflage Chevy Colorado ZR2 Bison caught testing 2019 GMC Sierra 1500 spied in base trim level 2018 Jeep Wrangler four-cylinder fuel economy revealed Spy Photos Chevrolet Dodge GMC Jeep Truck Coupe SUV Off-Road Vehicles Performance dodge challenger srt hellcat sunday drive
