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.

Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:

Macron and Le Pen decry 'shocking' Stellantis CEO pay

PARIS — French President Emmanuel Macron and his far-right challenger in the French presidential vote, Marine Le Pen, on Friday both decried as “shocking” the multimillion euro payout to the CEO of carmaker Stellantis. Stellantis CEO Carlos TavaresÂ’ remuneration package of 19.15 million euros just a year after the company was formed became an issue as Macron and Le Pen campaigned ahead of the April 24 runoff vote. Polls show purchasing power and inflation are a top voter concern. Stellantis was formed last year through the merger of PSA Peugeot and Fiat Chrysler Automobiles. Centrist President Emmanuel Macron, perceived by many voters as being too pro-business, called the pay package “astronomical” and pushed for a Europe-wide effort to set ceilings on “abusive” executive pay. “ItÂ’s shocking, itÂ’s excessive,” he said Friday on broadcaster France-Info. “People canÂ’t have problems with purchasing power, difficulties, the anguish theyÂ’re living with, and see these sums. Otherwise, society will explode.” Far-right leader Marine Le Pen, who enjoys support from many working-class voters, called for bringing in more workers as shareholders. “Of course itÂ’s shocking, and itÂ’s even more shocking when it is the CEOs who have pushed their society into difficulty,” she said Friday on BFM television. “One of the ways to diminish this pay, which is often out of proportion with economic life, is perhaps to allow workers in as shareholders.” Stellantis continued to back the package despite a 52.1% to 47.9% vote rejecting it at an annual shareholders' meeting chaired from the Netherlands, where the company is legally based, on Wednesday. The company, citing Dutch civil code, noted that the vote is advisory and not binding. The company later said in a statement that it took note of the vote, and will explain in an upcoming 2022 remuneration report “how this vote has been taken into account.” In the 2021 report, the company identified peer group companies that it used as a salary benchmark, including U.S. companies like Boeing, Exxon Mobile, General Electric as well as carmakers Ford and General Motors. Stellantis, whose brands include Peugeot, Fiat, Jeep, Opel and Maserati, reported net profits last year had tripled to 13.4 billion euros ($15.2 billion). The French government is the third-largest shareholder in Stellantis, with a 6.15% stake through the Bpifrance Participations S.A. French public investment bank.
