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.

Petrolicious profiles one man and his duo of '64 Impalas

Restoring any vintage car is a labor of love. In the end, the investment of time and money is often more than the vehicle is realistically worth on the open market. Deciding to take all of that work on yourself doesn't make things any easier, but it can only increase your connection to the project. Don Rogers, the subject of the latest video from Petrolicious, shows this passion perfectly with his duo of 1964 Chevrolet Impalas – a hardtop and convertible. Both of these Chevys had been sitting for years before Rogers got his talented hands on them, and he did all of the work himself. Now, driving the pair is therapy for him, and he's not worried about anything breaking because he knows he can put it back together. Rogers says he enjoys wrenching on his vehicles even more than going to shows. Doing your own work comes with advantages, like tailoring a project's look to your preferences. It's not original, but Rogers used the crimson interior color from a '59 Impala on his convertible to make the interior pop with the top down. Rogers is undoubtedly a talented builder, and his work is worth checking out in the latest from Petrolicious. Related Video:

Here's why automakers roll out those Texas-themed pickup trucks

Every year, automakers with a full-size truck link make a big show of the Texas State Fair, usually involving a reveal of a new model. Sometimes they show a whole new truck, and other times a special edition centered on the Lone Star state. While some people might write this off as a quirk of the industry, others might be wondering, "What's the big deal with Texas?" As it turns out, part of the big deal with Texas is big truck sales. According to Dave Sullivan, product analysis manager at AutoPacific, Texas buys more trucks than any other state in the country. It's not a small margin either. Edmunds.com, one in five trucks sold in the US are sold in Texas. The state also accounts for 15 percent of the country's large truck sales, which is more than twice that of California, the second largest truck market in America. Even when you break down sales only in Texas, trucks are a huge piece of the pie - Sullivan says that a quarter of new vehicle sales in Texas are trucks. One in five trucks sold in the US are sold in Texas. But it's not just sales that make truck builders give attention to Texas. As Sullivan explained, "Pickups are life in Texas." Both he and Hugh Milne, marketing and advertising manager for the Chevy Silverado line, said that trucks are key fixtures in Texas society, as both work trucks and luxury vehicles (or Texas Cadillacs as Milne called them). Milne said Texas is so important in the truck market that if you want to be successful in the rest of the country, "you've got to be successful in Texas." As for the State Fair, it has become a prime location for reveals in part because of the importance of the Texas market and because of how big the fair is. Milne also revealed that the State Fair also hosts its own auto show, so it's an ideal venue for a vehicle introduction. So there you have it. Why do truck builders obsess over Texas? It's because Texas obsesses over trucks. When you have one market that loves your product that much, you give it the attention it deserves.
