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.

Farley reacts as UAW expands strike against Ford, GM

Members of the United Auto Worker union walk out of the Chicago Ford Assembly Plant as Lance Williams from Lansing, Ill., waves the UAW flag Friday. (AP)   As the United Auto Workers walk off the job at an additional Ford and General Motors plant, Ford CEO Jim Farley addressed investors and members of the media Friday, pleading the case for the company's latest overture to the union and addressing both public and investor concerns regarding the core issues facing American manufacturing.  Farley made a public case for Ford's efforts to resolve the dispute, expressing frustration with the ongoing stalemate and noting both the concessions Ford offered before the strike began and the signing of a contract with Canada's Unifor. Farley also acknowledged UAW President Shawn Fain's success in getting the union's message out, quipping: "Shawn has been on TV more than Jake from State Farm at this point." The first-ever simultaneous strike against the Detroit Three automakers enters its third week with threats of continued expansion, but little in the way of obvious concrete progress.  "If the UAW’s goal is a record contract, they have already achieved this," Farley said. "It is grossly irresponsible to escalate these strikes and hurt thousands of families." Farley also lamented the fact that EVs have become the subject of partisan conflict, with the company's recently announced battery production facilities taking heat from both pundits and investors as Ford was forced to press pause on the venture while negotiations continue. Former President Donald Trump dropped in to Michigan this week to declare EVs the enemy of blue-collar jobs. "They've become a political football, and that's a shame," he said. Friday saw an expansion of the UAW strike to Ford's Chicago assembly plant and GM's Lansing, Delta Township, Michigan, assembly plant, covering about 7,000 workers, Fain said in an announcement, bringing the total number of workers on the picket lines to 25,000. The strike will not include any additional members at Stellantis, where talks have reportedly been more productive. The Ford and GM plants went on strike at noon Eastern today (Friday). Ford builds the Explorer and Lincoln Aviator in Chicago. GM's Delta Township plant builds Chevy Traverse and Buick Enclave. "Despite our willingness to bargain, Ford and GM have refused to make meaningful progress," Fain said in a video address Friday morning.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.
