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.

Pics Aplenty: Meet the 2014 Chevrolet Silverado and GMC Sierra [w/poll]

Today was a pretty big day for General Motors, debuting the all-new Chevrolet Silverado and GMC Sierra light-duty pickup trucks ahead of their official showcase at the 2013 Detroit Auto Show. And now that the dust has settled at GM's big reveal event, we've had a chance to snap dozens of photos of the new pickup pair from every angle.
We already told you the important bits earlier today (click here in case you missed it), but let's recap. Under the hood are three new engines - a 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 (you know, a version of the small-block that'll also be found under the hood of the C7 Corvette), all mated to six-speed automatic transmissions. The 2014 model year marks the return of the Z71 off-road package with Rancho shocks, front tow hooks and beefier underbody protection. Inside, there's a host of new technology and a greater focus on better quality and refinement.
Some of the nitty-gritty specifics (like engine output numbers and fuel economy) have yet to be revealed, and since we haven't driven the finished products yet, it's hard to say how these trucks will fare against rivals like the Ram 1500 and Ford F-150. For now, we can only judge these two books by their covers, and while we do like the designs of the new trucks, we Autoblog staffers are torn on exactly which one looks best.

GM's latest production delays: Colorado/Canyon, Cadillac CT4/CT5, Camaro

DETROIT — General Motors Co extended production cuts in North America on Wednesday due to a worldwide semiconductor chip shortage that has impacted the auto sector. The U.S. automaker said its Wentzville, Missouri, assembly plant would be idled during the weeks beginning March 29 and April 5. It will extend down time at its plant in Lansing, Michigan, which has been idled since March 15, by two weeks. The action was factored into GM's prior forecast that it could shave up to $2 billion off this year's profit, spokesman David Barnas said. GM did not disclose how much volume would be lost by the move, but said it intended to make up as much lost production as possible later in the year. The chip shortage came as North American auto plants were shut for two months during the COVID-19 pandemic last year and chip orders were canceled, and as demand surged from the consumer electronics industry as people worked from home and played video games. That's now left carmakers competing for chips. Semiconductors are used extensively in cars, including to monitor engine performance, manage functions for everything from steering to automatic windows, and in sensors used in parking and entertainment systems. Vehicles affected by the GM production cuts include the mid-sized pickup trucks, the Chevrolet Colorado and GMC Canyon in Missouri, and the Cadillac CT4 and CT5 and Chevy Camaro cars in Michigan. Meanwhile, GM said its San Luis Potosi, Mexico, assembly plant, idled since Feb. 8, will resume production with two shifts beginning the week of April 5. Last week, GM said it was building certain 2021 light-duty full-size pickups without a fuel management module, hurting their fuel economy performance by one mile per gallon. Exacerbating the shortage is a recent fire at a Renesas Electronics chip plant in Japan. Barnas said GM was assessing the impact of the fire.
