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.

2020 Chevy Silverado HD vs. 2019 Ram, Ford heavy duty trucks: How they compare on paper

Last year was all about the latest in light-duty full-size pickup trucks, so this year, Ram, Ford and Chevy are launching the heavy-duty variants. The first out of the gate is the redesigned 2019 Ram 2500 and 3500 HD, and Ram dropped all the pertinent specs with the reveal. Chevy followed with the new Silverado HD in Chicago, and Ford revealed updates to the Super Duty at the same show. Ford hasn't released details on output, payload capacity, towing capacity or pricing for the updated Super Duty. As such, we'll be comparing the current Super Duty with the all-new Silverado HD and Ram HD. Both Chevy and Ram have revealed full specs for each of their respective trucks, leaving out only pricing, which we've estimated based on the outgoing models. You can see the raw details in the chart below, followed by extra information and analysis. Some things to keep in mind: These specifications cover all versions of the Ram HD, Silverado HD and Super Duty, such as 2500 and 3500 models, and all the way up to F-450. Specifications can vary widely based on engine, drivetrain, cab and bed configurations, so be sure to take a close look at the specific model you're interested in when you get particularly serious about buying. And of course, be sure to check out our car comparison tool if you'd like to look at other trucks on the market. Engines and drivetrains All three of these trucks offer gasoline and diesel engines, but only the Ram has two versions of the diesel. Starting with gas engines, Ram's 6.4-liter V8 has the power advantage with 25 more horsepower than the next-most-potent Super Duty, but the new Silverado HD's 6.6-liter V8 takes the torque crown at 464 pound-feet, nearly 35 more than the other two gas engines. The Ram is also the only one to pair an eight-speed automatic with the gas engine, whereas the Ford and Chevy make do with a six-speed. With diesel engines, horsepower is a weak point for the Ram. The Ram's entry-level turbo 6.7-liter inline-six is the weakest, as the only one with under 900 pound-feet of torque and under 400 horsepower. Even the high-output version only makes 400 horsepower, while the Chevy makes 445 and the Ford 450. But the tables turn with torque, as the Ram makes a best-in-class 1,000 pound-feet followed by the Ford's 935 and the Chevy's 910. Both the Ram and the current Super Duty diesels each get a six-speed automatic, but the new Silverado HD's diesel gets a 10-speed unit.

New Toyota Tacoma, Ranger, Colorado/Canyon fight for midsize truck dominance

Sam Wedll has been driving his Toyota Tacoma pickup on the rugged roads of Northern California for seven trouble-free years, racking up almost 100,000 miles, so he’s interested in the redesigned version of the truck coming later this year. He paid $34,000 for his truck in 2016, loading it with plenty of options. HeÂ’s eyeing the new gas-electric hybrid Toyota Motor Corp. is going to offer, but Wedll, who does his own repairs, isnÂ’t interested in paying luxury prices. “The hybrid is pretty interesting to me because I like the idea of the fuel efficiency,” says Wedll, 47, a casino operations manager in Blue Lake, California. “IÂ’m just trying to save some costs wherever possible.” The Tacoma, known as the Taco to its legions of loyalists, is the leader of the pack in midsize pickups, one of the fastest-growing auto markets of the past decade. With outdoorsy weekend warriors and do-it-yourselfers looking for a truck that could fit in their garage, sales of midsize pickups more than doubled from 2010 to 2020. General Motors Co. and Ford Motor Co., which abandoned the market segment when sales slowed early this century, returned with new trucks to take on the Tacoma, which has dominated the medium truck market for almost two decades. Although it's easy to predict that the most lushly appointed versions of the new Taco could approach $50,000 (prices wonÂ’t be announced until later this year), Toyota insists it isnÂ’t backing away from budget buyers even as it rolls out fancier trucks. The current Tacoma starts at $28,030, and the company says affordability is critical to its success. In fact, Toyota will continue to offer the Taco with an old-school stick shift. The Tacoma controls 42% of the midsize truck market and outsells FordÂ’s offering 4 to 1. ThatÂ’s a role reversal from the full-size pickup market, where FordÂ’s F-Series has ruled the road for 46 years. Tacoma sales in the U.S. surpassed 237,000 last year, more than twice the number of GMÂ’s No. 2-ranked Chevrolet Colorado, according to consultant LMC Automotive. But as growth in the overall segment slows, the midsize market is developing into more of a turf war, with manufacturers vying for the sweetest highest-margin spots. “This segment is likely past its prime growth spurt,” says Jeff Schuster, president of the Americas for LMC Automotive.
