Is Buick's surprise Detroit concept a Camaro-sized coupe?

Tomorrow night marks the unofficial start of the 2016 Detroit Auto Show. Keep your eyes peeled for a number of reveals, including a surprise debut from Buick. Yes, Buick. And we think it's going to be something really hot. According to a report from Bloomberg, the Tri-Shield's secret car could be a Camaro-sized sport coupe concept. As Bloomberg explains, it'd certainly gel with the impression the company is trying to put out – that it's no longer a brand for those with one foot in the grave. Introducing a sports coupe, even as a concept, could certainly reinforce that message. And if it happens to make production – which is not a certainty, Bloomberg's secret source says – it could certainly help Buick drive its average buyer age down from 59. Bloomberg doesn't offer any speculation on Buick's new coupe, but we have no problem making educated guesses. Our most reliable conjecture is this: it will ride on General Motors' Alpha platform, which underpins both the Camaro and the Cadillac ATS. And with a certain twin-turbocharged V6 in the GM stable, we've got an idea of what kind of engine could be shown. That speculation will have to suffice for now. But don't worry, we'll have official details, live images, and video tomorrow when Buick unveils its new concept in Detroit's Eastern Market.

Man surprises girlfriend with C7 Corvette

How would you react if someone just showed up at your place of work with a new, 2014 Chevrolet Corvette Stingray, complete with all the trimmings? While a lot of us would likely be flipping out over the still rare sports car, it's a fair bet many more of us would be responding like Pattie here, whose boyfriend stopped by her work to show her her new C7.
Speechless and shocked as she seems, she does end up taking it out for a drive, despite claiming she wasn't really outfitted to handle the car's seven-speed manual transmission at the time. From the sound of the video, we got the impression that she knew the car was coming, just not that it was anywhere near ready for delivery. It also, as Pattie says, seems like her boyfriend is more excited about the car than she (which, can we blame him?). Take a look down below for the full video of this C7 Stingray delivery.

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.
