First 2014 Chevy Corvette Stingray spotted crashed in the wild

This restyled blue 2014 Chevrolet Corvette Stingray is wearing manufacturer plates, and it appears to be the same one seen around the internet in various pictures lately. This crash is likely not part of the Chevrolet testing regimen, however. Digital Corvettes forum member gpetry posted the shot with a note: "got this picture e-mailed from a friend in Arizona last week..." No circumstances are given, other than the incident occurred in the thick of a set of curvy roads, and the coupe ping-ponged off a guardrail and into the rock wall. Hopefully everyone involved in the incident walked away.
It may not be a pretty thing to see, a crashed sports car that's not even available for sale yet, but rest easy. Many pre-production cars are used for development and then unceremoniously crushed and scrapped, anyway. If that's the case here, that makes this wrecked 'Vette less of a tragedy and more of a case of exceptional efficiency.

GM takes 2020 full-size pickup sales crown

It's no secret that 2020 was an unconventional year for auto sales. Extenuating circumstances or not, it was a year of upheaval even for ever-resilient (and ever-profitable) pickups, with General Motors taking the crown from Ford in the full-size segment.  The Ford F-Series still outsold every other full-size pickup nameplate in the country by a significant margin. It's only when you combine GM's Chevrolet Silverado and GMC Sierra variants that you get a number that exceeds Ford's. This isn't really a new phenomenon, either. In fact, it was only somewhat recently that Ford took the overall full-size crown away from GM, and not only did Ford widen the gap in recent years, but Ram has once again become a legitimate challenger, even managing to outsell the Silverado by a healthy margin in 2019, but never coming close to the F-Series in terms of total volume.  But, 2020 being 2020, things got weird yet again. Ram remains relevant, of course, but Ford got caught with its pants down thanks to the one-two punch of COVID and the generational changeover of the core F-150 model, which resulted in a production interruption as the company's assembly facilities transitioned from building the old 2020 model to the new-for-2021. This perfect storm, as it turns out, was sufficient for GM to walk away with the full-size crown. See for yourself: Full-size 2020 pickup sales: GM total: 847,110 F-Series: 787,422 Silverado: 594,094 Ram: 563,676 Sierra: 253,016 Tundra: 109,203 Titan: 26,439 As you can see, Ram slipped back behind Silverado, slotting comfortably into third place. The Silverado 1500 had a flat year, but the heavy- and medium-duty variants bucked the trend and contributed to a slight uptick in sales for the nameplate, while F-Series tumbled more than 12% (nearly 110,000 units), opening the door for GM to steam ahead.  There were similarly significant shakeups in the midsize truck segment. First, 2020 was the first full year of retail sales for the Gladiator pickup, which surged to fourth place behind the stalwart Tacoma, Ranger and Colorado. GM's combined sales of the Colorado and Canyon are good enough for second place by manufacturer, but nowhere close to what it would take to dethrone Toyota.

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.
