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.

Road Race Motorsports rolls out Fiat 500 M1 Turbo Tallini Competizione

We've seen some pretty radical modifications based on the Fiat 500 - from the Abarth 695 Biposto to that ridiculous idea to put a Ferrari engine in the back of a Cinquecento - but we never seem to get tired of it. On that note, we bring you the Fiat 500 M1 Turbo Tallini Competizione.
Built by Road Race Motorsports, the M1 takes a tarmac-rally approach and features an extensive list of modifications. For starters, the engine has been retuned to produce 250 horsepower and 250 pound-feet of torque, helping to knock a second off the 0-60 time (7.2 seconds from the factory). Upgraded brakes net a 20-percent improvement in stopping distance, and Road Race has put a special emphasis on high-speed stability and cornering performance.
Other modifications include a limited-slip differential, carbon-kevlar clutch and a reworked suspension with Bilstein shocks, stiffer bushings and upgraded sway bar, with 16-inch wheels wearing Toyo Proxes rubber. In addition to a full carbon-fiber widebody kit that helps cut 120 pounds off the curb weight, Road Race has given the M1 a new front air dam, side skirts, hood vents, brake ducts and rear spoiler. The interior has similarly been upgraded with racing buckets, five-point harnesses and a roll cage.

What a 28.5-liter LSR engine sounds like firing up for the first time in 100 years

Racecars seem to keep getting quieter these days, and if electric vehicles and fuel cells ever fully take over motorsports, then the bang, pop and growl of internal combustion engines may be gone for good. This clip of a Fiat S76 land speed record racer awaking after over a century of being dormant shows just what we would miss so much. The four-cylinder engine in this Fiat displaces about 28.5 liters, making it among the largest automotive engines ever, and it gives each cylinder around as much capacity as the whole mill in a Chevrolet Camaro Z/28. Once this thing starts firing with no exhaust in place, the look and sound is like a demon at work with a rain of fire and sparks. This clip is just the trailer for a documentary called the Beast of Turin chronicling the history of this period of racing. The movie also focuses on the rebuild and restoration of the S76 after over 100 years. If the rest of the film lives up to this tease, then it looks like something to watch for.
