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.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

Personal testimonies show real-world effect of plugging in with Chevy Volt

At this point, there are tens of thousands of individual stories about what it's like to live with a Chevrolet Volt. But it also remains informative to take a look at one of these in depth. For example, one Atlanta-area Volt owner says he's cut his cents-per-mile ownership costs by almost 40 percent compared to his previous car primarily because of his ability to drive almost all the time on electric power. Jeffrey Cohen told Clean Technica that he put about 14,000 miles on his Volt extended-range plug-in hybrid for the year that ended October 2013, and that more than 92 percent of those were on electrons. He estimates his "lifetime" miles per gallon rating at a whopping 384 mpg, a figure pushed upward by the fact that he installed a Level 2 charger at home while his employer added an external 110-volt charger at work. Cohen is spending 45 cents a mile for his car, compared to 73 cents in his Infiniti M35. As a result, he's spending 45 cents a mile for his car, compared to 73 cents a mile with his prior vehicle, an Infiniti M35. About two-thirds of those Volt costs are for the $349-a-month lease payments, while 15 percent is insurance, 11 percent is for the charger and seven percent for the gas and electricity that actually powers the car. Helping lower that last figure is an overnight electricity rate that's about 10 percent of Cohen's daytime rate. Chevy parent General Motors hopes such testimonies will re-trigger sales for the Volt in 2014. Last year, GM sold 23,094 Volts, down 1.6 percent from 2012.
