Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

GM execs fired over fraudulent India emissions testing

General Motors hadn't had a recall in India since 1995. That changed when it was discovered that certain employees were playing tricks with local emissions testing in order to ensure passing grades for engines. More than ten GM Powertrain employees in India and the US have been let go over the ensuing emissions flap, including Sam Winegarden, VP of global engine engineering, a man who has been with the company since 1969, leading development of some marquee powerplants.
According to Automotive News, an internal investigation revealed that employees "violated testing procedures," sometimes swapping specially prepared low-emissions engines during testing regimes for the Chevrolet Tavera SUV equipped with the 2.0-liter and 2.5-liter engines. Employees were also manipulating weights in order to get vehicles placed into different emissions categories. The discovery has led to GM recall the 114,000 Taveras produced over an eight-year period and halting their production and sale.
The Economic Times of India reports that the issue is due to "a faulty component." GM has developed a solution to the issue, and once it is validated in testing and approved by the Indian authorities, the recalled vehicles will be fixed at dealers and production will resume.

Chevy up to old EVs-equal-range-anxiety tricks in new Volt Olympics ad

General Motors is at it again with a new Chevrolet Volt TV commercial. Viewers of the Winter Olymics (at least in some markets) recently saw a TV ad in between the skating and the skiing that made no mention of the environmental benefits or freedom from the power of Big Oil that electric vehicles provide. No, this one was based on pure survival instinct. In the video, a father is driving down a highway, perhaps through the Mojave Desert. His young son is sitting in the Volt's backseat and asks what happens when the EV's battery runs out. "We'll have to cross that burning desert with snakes and cactus until we make it back to civilization," the dad tells his son as they pass the skeleton of a fallen bull. The fine print makes it clear that the actual maximum range is 342 miles. But there is hope. The father tells his son, with a beaming smile on his face, that the gas generator has kicked in and they're going to make it through the desert. As they wend their way to the horizon, a voice over says that Volt drivers who charge up regularly are making it 900 miles between fill ups. The fine print makes it clear that the actual official maximum range before you need to either plug in or fill up is 342 miles. This theme that emphasized range anxiety has been utilized by GM since the extended range Volt was launched in late 2010, despite the fact that Chevrolet now offers an all-electric vehicle in the Spark EV. Volt fans are praising the commercial, called The New Freedom, on the GM-Volt forum and you can see for yourself below. This content is hosted by a third party.
