For one, the Corvette ALMS racers are actually powered by a V8 loosely based on the Z06’s LS7 engine (see the second video after the jump). Perhaps most importantly, the Corvettes finished third and fourth in the GT class in Sebring behind two BMW M3 GTs… Videos follow after the break.

Lurking behind that angry looking fascia is 6.2-liter V8 powerplant pushing out an estimated output of 550-horses and a ferocious peak torque of 550 lb.-ft. of torque (745 Nm), channeled to the rear wheels through a six-speed manual stick shift. We've posted a more detailed preview here but if you hit the jump, you can check out live pictures from the Chicago Auto Show reveal as well as the first video of the car.
After some recent fails, let’s see a dyno test with a happy ending. This is a 2005 C6 Corvette built by Dallas Performance, which recorded a whopping 1,302 hp and 1,662 Nm (1,226 lb-ft) of torque on the rear wheels, according to the performance charts.
To achieve this, the tuning firm upgraded the V8 powerhouse with twin turbos, Performance Induction LS3 heads, RC120 injectors and single plane intake. The power is transferred to the rear wheels through a TR-6060 transmission and a C6 Z06 differential. The clip is available after the break.

Nowadays, the appearance of all-electric and extended range hybrid electric cars in showrooms has forced [ahem...] the U.S. Environmental Protection Agency (EPA) to embrace a new method to measure the energy consumption of alternative fuel vehicles called MPGe (Miles Per Gallon Equivalent).

The answer lies, in part, with the Aerovette: a mostly forgotten concept that made just two auto show appearances before being relegated to the GM Heritage Museum.
In the late ‘60s, GM engineer Zora Arkus Duntov and his team were toying with the XP-882, a mid-engined design and engineering exercise built on Oldsmobile Tornado underpinnings. Though fascinating from a design and engineering standpoint, Chevy General Manager John DeLorean saw no future for the XP-882 and canceled the project in 1969. It was simply too expensive and too impractical for the impending 1970s America.

Still, I'd find it hard to believe that anyone, even lovers of the '09 Concept, would consider putting down over US$40 grand on this so-called replica. It's even harder to believe that underneath all that fibreglass is a 2005 C6 Corvette; it could just have easily been based on a twenty year old Mazda Miata / MX-5 like so many other eBay customs.
So what does the US$42,500 "Buy It Now Price" get us? For starters, the underpinnings from the C6 Corvette including its 440 hp LS2 V8 and 6spd automatic transmission. You get a clear title and 29,111 miles on the odometer to boot.
GM says the conversion from coupe to convertible comprised of four strategic reinforcements to enhance the body structure including, the addition of a tower-to-tower brace under the hood, a transmission support reinforcement brace, underbody tunnel brace and, front and rear underbody "V" braces. The company's goal was to match the coupe as closely as possible in ride quality, handling and overall performance.
The Texas-based tuner claims that the HPE600 is capable of completing the 0-60mph (96km/h) sprint in the mid 3-second range and run the quarter mile (~400 meters) in 11 seconds.
Underpinned by a 2007 C6 Z06, the most important aspect of the SixtySix concept is its appearance, which takes its fair share of styling inspiration ("the best of everything") from vintage Vettes.
The car was designed by David R, who hopes to be selling turn-key models for $120,000-$130,000 via his Rossi Motor Company in the near future. Other than retro exterior cues, the SixtySix also has a modified suspension/wheel/brake setup, power rear hatch, and a revised interior with rear-view camera.
