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.

Junkyard Gem: 1988 Chevrolet Spectrum Sport Coupe

Before General Motors created the Geo brand for cars built or designed by its overseas partners, the Chevrolet Division put its badges on U.S.-market versions of the Toyota Corolla Sprinter, the Suzuki Cultus and the Isuzu Gemini. Those cars were known as the Nova, the Sprint and the Spectrum, and all became Geos starting with the 1989 model year. Today's Junkyard Gem is one of the last Chevy Spectrums ever sold, found in a Denver self-service yard a few months ago. Midway through 1988, the Chevrolet Spectrum abruptly became the Geo Spectrum and was assigned to the 1989 model year. This car was built in May 1988, making it one of the very last of the pre-Geo Spectrums. The Chevrolet/Geo Spectrum was available as a four-door sedan and as a three-door hatchback, from the 1985 through 1989 model years. For 1988 only, a Spectrum Sport Coupe package, featuring some trim upgrades and these rad decals, could be had on the hatchback. This car was essentially identical to its Isuzu-badged counterpart, the I-Mark. In 1988, the MSRP for the cheapest possible Chevy Spectrum hatchback (the stripped-down Spectrum Express) was $6,495, while its somewhat better-equipped I-Mark twin started at $7,439 (that's $17,128 and $19,617 in 2023 dollars). Meanwhile, the base Hyundai Excel hatchback listed at $5,295 and the Yugo GV cost a hilarious $4,199 ($13,963 and $10,941 in today's money). Power came from this 1.5-liter SOHC four-cylinder, rated at 70 horsepower. A turbocharged version with 110 horsepower was available as well. You could get an automatic transmission in the Spectrum, but this car has the base five-speed manual. This car didn't get the optional air conditioning, but at least it has the traditional Isuzu HVAC control icons featuring blow-dried hair and high-heeled dominatrix boots. Just over 170,000 miles on the odometer. Someone installed a pretty good (for the 1980s) Blaupunkt Charlotte CR148 cassette deck in the dash. This was a necessity if you wanted to enjoy full appreciation of the music of the era. The Spectrum is special! It's as slick as city rain. "I didn't spend a lot of money but with my Spectrum it looks like I did." Joe Isuzu mocked Toyota salesmen when pitching the I-Mark. As was nearly always the case during the 1980s, the JDM ads for the same car were much more fun. They should have recreated this commercial with Spectrums.

National Corvette Museum to recreate sinkhole experience for patrons [UPDATE]

UPDATE: The Thunderdome at the National Corvette Museum is not a ride; instead it's an experience that mixes digital graphics and thundering sound. For a brief period, it looked like the National Corvette Museum was going to preserve that sinkhole that ate eight important 'Vettes last year. After all, tourism boomed there afterwards. However, keeping the crater would have been more expensive than just doing the repairs. The museum isn't ready to let people completely forget, though, and now intends to make a major attraction out of a recreated version of the calamity. The museum's plan turns the sinkhole disaster into an amusement park ride called the Thunderdome, according to GM Authority. In a smaller recreation of the Skydome, 15 people at a time would get to watch an imitation of the sinkhole devouring the eight Corvettes. To make the experience even more immersive, visitors would get to view this all from an artificial, underground cave. If you missed seeing the actual pit, this would certainly be a bizarre way to experience it. According to GM Authority, the exhibit would also include an explanation of how sinkholes occur. The Corvette museum reportedly wants the attraction open by this fall.
