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.

Petrolicious shines the spotlight on a little-known, Fiat-based racecar

Petrolicious has a way of finding intriguing, obscure vehicles that are owned by fascinating people all across the world. In this latest video, the filmmakers discover the soft-spoken Fabrizio Lorenzoni in Italy and showcase his utterly gorgeous Fiat 1100 Stanguellini. Stanguellini was a mechanic from the sports car hotbed of Modena, Italy, who earned a name for himself by modifying Fiat engines for racing. This one started its competition life in 1948 with open wheels but gained these curvaceous fenders a few years later for events like the Mille Miglia. Lorenzoni was lucky enough to grow up right on the course of Parma-Poggio di Berceto road race. His father must have loved seeing the Italian sports cars zipping by the home, too, because he bought the Stanguellini in 1955 with no intention of racing. It wasn't until 1977 that Fabrizio put the roadster back into competition. Petrolicious shoots Lorenzoni crammed behind the wheel of the little Stanguellini on some bucolic, Italian roads. It's absolutely a beauty to behold.

Abarth 124 Spider is one furious Fiata

If you've been thinking of picking up a nimble new roadster, but can't decide between the Mazda MX-5 Miata and its Italian counterpart the Fiat 124 Spider, the vehicle you see here might tip the balance. It's the new Abarth 124 Spider, tuned by the Italian automaker's performance division. And it's just made its debut here on the floor of the 2016 Geneva Motor Show. The Abarth version, of course, is based on the Fiat model, which in turn is based on the Mazda. But the one with the Scorpion emblem offers a number of performance upgrades. Under the hood is still a 1.4-liter turbo four, producing the same 184 pound-feet of torque, but in Abarth spec offers a more prodigious 170 horsepower (up from 160). Buyers will still be able to choose between a six-speed manual or automatic transmission, but the rest of the components are no-brainers: Brembo brakes, Bilstein dampers, and a Record Monza exhaust. The steering is electrically assisted, but it has a proper mechanical limited slip differential, there's a Sport button, and the electronic nannies can be fully defeated for hooning around on track. The sum total is a 0-62 time quoted at 6.8 seconds and a top speed at 143 miles per hour. Bear in mind that these are specs for the European model, though, and could change if and when the Abarth spider makes its way to our shores.

There's a full aero kit, larger air vents, 17-inch alloys, and a black hood to cut down on glare (and make it look more businesslike). The interior is all done up in Alcantara, with a small-diameter steering wheel, short gear lever, aluminum pedals... the works. As if all that isn't enough to get your motor running, Abarth has also worked up a rally version to recall its glory days of old. The Abarth 124 Rally is built to FIA R-GT regulations, and ditches the 1.4-liter engine for a 1.8 mounted further back and producing an impressive 300 hp. It also has a fixed roof, full roll cage, and a long list of other competition-spec upgrades that are too long to list here, but you can read all about them in the second of the two press releases below.
