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.

Next-gen Chevy Camaro ZL1 teases big changes under its camo

With work complete on the lighter, stiffer 2016 Camaro, it's time for Chevrolet's engineers to really start having fun by developing the next, ZL1 version. Here it is for the first time. Unfortunately, the muscle car is still wearing quite a bit of camouflage, but the concealment isn't enough to hide some of the meaner model's more obvious performance tweaks. Starting from the front, this Camaro now wears a much more aggressive front fascia with bigger air inlets. Managing the airflow around the engine bay is clearly a big deal because another photo reveals a fairly large extractor in the hood, as well. Moving down the profile, the lower side sills and orientation of the camo suggest some blistered fenders in the back to cover wider rubber, and at the very rear a much larger wing further suggests the need to keep things planted to the road. Check out the comparison images in the gallery for a better look at the tweaks. What will power the next ZL1 is still entirely a mystery, although sticking with a supercharged 6.2-liter V8 could be a possibility, especially if you take the big extractor in the hood as a hint. Whereas the current ZL1 makes 580 horsepower and 556 pound-feet of torque, the LT4 in the latest Cadillac CTS-V pumps out 640 hp and 630 lb-ft. Combined with the Camaro's other improvements, we're thinking that this new ZL1 will be quite a hot ticket, and based on these spy shots, we can't wait to find out.

New recall issued in 2019 Chevy Silverado and GMC Sierra brake software saga

General Motors (GM) has issued a new recall for select 2019 Chevy Silverado 1500 and GMC Sierra 1500 pickup trucks that aims to resolve a faulty fix for a previous recall. According to National Highway Traffic Safety Administration (NHTSA) campaign No. 20V055000, a software update for the Electronic Brake Control Module (EBCM) could cause the electronic brake assist to be disabled.  The NHTSA first launched a recall for 463,995 Silverados, Sierras, and Cadillac CT6es on December 12, 2019 due to a software issue in the electronic brake control module (EBCM) that could disable the electronic stability control (ESC) and anti-lock braking system (ABS). As a response and resolution to that recall, GM began to reprogram the software in affected vehicles. GM later learned that the fix was creating a different problem. The installed software had its own error that was disabling the electronic brake assist. If customers see “Service Brake Assist” or “Service ECS" diagnostic warnings, they should park the vehicle and have it towed to a dealership, GM warns. While GM was going through the process of testing, pinpointing the issue, determining action and working with the NHTSA, safety experts have criticized Chevrolet and GMC for not reacting promptly and appropriately.  According to the recall, 148,055 are now affected, all of which do not meet the standards of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems." To fix the braking issue, GM will once again reprogram the software. GM began notifying owners of the recall on February 10, 2020. Related Video:
