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.

GM learning from current Chevy Volt owners as it works on next-gen model

Details of the second-generation Chevrolet Volt extended-range plug-in hybrid are coming in at a trickle, and the latest is that the 2016 model-year Volt will be improved in all meaningful areas, including performance and all-electric range, says General Motors powertrain director Larry Nitz. 60 percent of Volt customers only charge using a standard 110 outlet. Nitz was speaking to Autoline After Hours about the current and future Volt. He said that GM has been tracking Volt driving habits and found that about two-thirds of the Volts' collective miles are driven in electric mode, and that 81 percent of all Volt trips were done in pure EV mode. Additionally, Volt drivers plug the car in 10 times each week, on average. Nitz also said 82 percent of the Volt's commuting miles are coming from the plug instead of the gas tank. Oh, and 60 percent of Volt customers only charge using a standard 110 outlet. Last month, GM released a teaser shot of the 2016 Volt (above) and said the car would make its worldwide debut at the 2015 North American International Auto Show next January. Earlier this year, the Volt was reported to be getting a new chassis for the upcoming version. The Volt could use a bit of new life. Through August, Volt sales were down 12 percent from a year earlier to 13,146 units, and sales plunged 25 percent alone. That compares unfavorably to the Nissan Leaf battery-electric vehicle, whose 2014 sales have jumped 34 percent to almost 19,000 units. You can see Nitz dish the goods in the video below (Volt comments start at around minute 15).

GM and Ford quarterly sales continue to slump in China

BEIJING — General Motors and Ford announced their quarterly sales in China fell, albeit at a slower pace sequentially, as the U.S. automakers were hit by a slowing economy amid the Sino-U.S. trade war. GM's vehicle sales in China for the quarter ended June 30 dropped 12.2%, while Ford's sales slumped by 21.7%. While GM also suffered from heightened competition in its key mid-priced SUV segment, Ford was hurt by the limited new models for customers to choose from. For the first quarter of this year, Ford's sales in China tumbled 35.8 percent while GM's skid 17.5 percent. Still, the numbers from GM, the second biggest international automaker in China by sales, and Ford portend more uncertainty for the industry which is trying to rebound from a downward spiral that led to its first annual sales decline last year in more than two decades. GM delivered 1.57 million vehicles in China in the January-June period this year, while Ford delivered 290,321 vehicles. China's factory activity shrank more than expected in June, highlighting the need for more economic stimulus amid higher U.S. tariffs and weaker domestic demand. Annual car sales in China fell last year for the first time since the 1990s, and they are expected to fall this year too. Sales tumbled 16.4% in May from the same month a year prior, the China Association of Automobile Manufacturers (CAAM) said. That marked the 11th consecutive month of decline and followed falls of 14.6% in April and 5.2% in March. U.S. car companies' share of total China passenger vehicles sales fell to 9.6% in the first five months of this year from 10.9% in the year-ago period, according to CAAM. Over the same period, German car makers' share has risen to 23.3% from 20.9% and Japanese auto makers' to 21.3% from 17.3%. CAAM is set to announce June sales next week, which industry analysts forecast will be negative.   New models In China, GM has a joint venture with SAIC Motor Corp, in which the Buick, Chevrolet and Cadillac are made. It also has another venture, with SAIC and GuangxiAutomobile Group, in which they make no-frills minivans and have started to make higher-end cars. Sales of GM's affordable brand Baojun dropped 31.8% for the latest quarter. But luxury brand Cadillac's sales jumped 36.6%. GM sold 3.64 million units in China last year, down from 4.04 units in 2017. Ford makes cars in China through its joint venture with Chongqing Changan Automobile Co and Jiangling Motors Corp (JMC).
