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.

2023 J.D. Power Initial Quality Study shows there's less quality than last year

Vehicle inventory, vehicle pricing, and the supply chain are finally showing improvement. Vehicle quality, on the other hand, is still going the wrong way. That's the takeaway from the 2023 J.D. Power Initial Quality Study that found overall problems exceeded last year's record high. The study surveyed owners of 2022-model-year vehicles to assess the average rate of problems per 100 vehicles (PP100) during the first 90 days of ownership. The average figure for the 32 ranked manufacturers in 2020 was about 166 problems per 100 vehicles. In the 2021 IQS, that dropped to an average of 162. For 2022, the average jumped to 180 problems. For 2023, the PP100 is up to an industry average of 192 — an increase of 30 problems per 100 vehicles in just two years. Let's get to the good news first: Dodge reclaimed the crown of having the lowest number of problems per 100 vehicles at 140. Buick won last year with 139 PP100, falling to third this year. Dodge was the first American automaker to top the IQS in 2021. Its return as the least problematic gives parent company Stellantis three wins in four years after Ram was crowned in 2021. It also gives U.S. brands a four-peat after Buick topped the chart in 2022 by having owners report the fewest problems. This year's top 10 is Dodge, Ram, Alfa Romeo, Buick, Chevrolet, GMC, Porsche, Cadillac, Kia, and Lexus. Stellantis gathered a few feathers for its cap, in fact. Maserati showed the largest improvement year-on-year, followed by Alfa Romeo, and Alfa Romeo posted the lowest PP100 among the premium class, beating Porsche and Cadillac. Alfa Romeo has been vocal about working to improve quality, mentioning Lexus as a target. Last year the Japanese brand finished sixth, the Italians finished near the bottom, between Jaguar and Mitsubishi. This year Alfa jumped to third, Lexus dropped to tenth. Ram was the third-best on the list of improvers from 2022 to 2023.   The individual model with the lowest PP100 is the Nissan Maxima. Now for the troublesome bits. In the words of Frank Hanley, senior director of auto benchmarking at J.D. Power, "The industry is at a major crossroad and the path each manufacturer chooses is paramount for its future.

2017 Chevy Bolt Prototype Quick Spin [w/video]

To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. To say that there's a lot riding on the upcoming Chevy Bolt doesn't quite get at how important this all-electric vehicle could be for GM. We are entering a new phase for EVs in the US, and it's one where there will be more than one 200+ mile range electric model that will cost around $30,000-$35,000. The two obvious first entries are the Tesla Model 3 and the Bolt, but you can bet your Level 2 charger that Nissan will be joining the party as well, along with all sorts of as-yet-unannounced entries from other automakers. The main change that all of these longer-range EVs will bring is – potentially – to make plugging in your car a mainstream thing. And if the mainstream is in play, then there's money to be made, and you're going to need one heck of an EV to get people to pick your car instead of someone else's. So, yeah, the Chevy Bolt could be a big deal. And today we not only got a bit more information about the car but we also got to go on a really short test drive in a prototype version outside of the Las Vegas Convention Center as part of CES 2016. The "drive" took place in a closed-off parking lot and my two laps through the cone course took less than three minutes, but I can still say that it looks like GM will be bringing a solid option to the marketplace soon. Chevy Bolt Prototype front 3/4 View 16 Photos If you shift into L, the regen becomes wonderfully strong. One of the pleasant surprises in the Bolt prototype is the ability to drive with just one pedal. When in D, the Bolt coasts a bit, which is nice for highway driving, but if you shift into L, the regen becomes wonderfully strong. Strong enough that you don't need to engage the brakes at all if you're in standard city traffic, with lots of gentle stops and starts. If you want even more stopping power without getting the brakes involved, the Bolt also has the regen-on-demand feature that was introduced in the Cadillac ELR and works great in the second-gen Chevy Volt. When you pull the paddle on the left back side of the steering wheel, the electric motor instantly becomes a generator and the Bolt turns forward momentum into energy for the battery pack. It will even bring the car to a complete stop and then hold it when you release the paddle.
