Corvette Stingray designer lists five goals of new exterior shape

Redesigning an icon is a difficult task, especially when you've got a blank sheet of paper in front of you and the all-new C7 Chevrolet Corvette Stingray is intended to be your final objective.
General Motors has released a new short video featuring Kirk Bennion of the Corvette's exterior design team, talking about the challenges of sculpting Chevrolet's new flagship sports car and the five goals the team had to keep in mind as it worked. In the end, Bennion's team had the pleasure of seeing their hard work take center stage as the Corvette captured the world's eyes at the Detroit Auto Show earlier this year.

Least reliable cars and trucks of 2022

Related: Most reliable cars and trucks of 2022   Every year, Consumer Reports ranks new cars based on their predicted reliability. We often see Toyota, Lexus, and a few other automakers near the top. But on the other side of the coin, the list of least reliable vehicles sometimes contains surprises.   The organization surveys its members to determine the vehicles that exhibited the most problems over the prior year. Owners are asked about creaks and rattles, the durability of parts and trim, and mechanical issues. Consumer Reports assigns a weight to each problem and then uses them to create a score, with 100 being the best. Some familiar names appear on the list of least reliable vehicles (in order with the lowest predicted reliability score at the top), but there are a few eyebrow-raising models, followed by CR's score: Ford F-150 Hybrid: 4 Hyundai Kona Electric: 5 Lincoln Aviator: 8 Nissan Sentra: 9 Ford Explorer: 16 Chevrolet Bolt: 17 Chevrolet Silverado 1500/GMC Sierra 1500: 19 Jeep Gladiator: 21 Mercedes-Benz GLE: 23 Jeep Wrangler: 24 Consumer Reports noted that sedans are the most reliable vehicle category and found that trucks are far lower on the list. That said, the survey showed that trucks from American brands tended to have better reliability scores, so it’s surprising to see GMÂ’s big two and the Ford F-150 on the list. Part of their problematic ownership experience could be due to the fact that all three trucks have received recent updates, and the Ford was completely redesigned for 2022. New tech, fresh drivetrain components, and other improvements can upset the balance of reliability and make newer models look less dependable than their older counterparts.

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.
