In addition to the power plant, the 2007 Corvette Z06 differs from the C6 with a lightweight chassis, aerodynamic body panels, upgraded brakes and a spiffed-up interior. This most-powerful production Corvette is hardly a daily driver, but smooth clutch and gearshift actions ease driving in a city scenario. The extra-tall sixth gear makes highway cruising comfortable, but the tires are very noisy over concrete surfaces. GM warns them of the possible ouster from the roads with the launch of its fastest production car, the 2007 Corvette Z06. This sports car has got a brilliant acceleration from zero to 60mph in less than 4 seconds, a quarter mile in the mid 11-second range and the top at 190mph.

The LS7 all-aluminum, 7.0-liter small-block V-8--hand-assembled using premium hardware like titanium connecting rods and a dry-sump oil system--is GM's most powerful production car engine ever, delivering 505 fire-breathing horsepower and 470 pound-feet of torque. The rest of this special Vette is equally top-drawer: lightweight, all-aluminum chassis; magnesium engine cradle; carbon-fiber front fenders; six-piston cross-drilled front brakes.

With 505 horsepower produced from a hand-assembled 7.0-liter LS7 V-8, the 2007 Corvette Z06 easily outpaced the mighty 8.3-liter Viper SRT-10 Coupe-which has made the Dodge boys quite angry.

One of the clearest examples of the LS7's race-bred technology is its use of titanium connecting rods. They weigh just 480 grams apiece, almost 30 percent less than the rods in the LS2 V-8. Upon introduction, the Coupe LT1 is equipped with a standard 6.0-liter, V8, 400-horsepower engine that achieves 18-mpg in the city and 28-mpg on the highway. A 6-speed manual transmission with overdrive is standard, and a 6-speed automatic transmission with overdrive is optional. SEMA, an automotive specialty products trade show, runs from Oct.

The LS7 has a dry-sump oiling system designed to keep the engine fully lubricated during the high cornering loads the 2007 Corvette Z06 is capable of producing. An engine compartment-mounted 8-quart reservoir delivers oil at a constant pressure to a conventional-style oil pump pick-up at the bottom of the engine. Ethanol production has grown tremendously during the last three decades and has allowed the country to practically wean itself completely from imported oil. The 2007 Corvette Z06 certainly is a respectable machine, made even more impressive by being the cheapest production supercar in the market.

The 2007 Corvette prices leap from $45,000 for the coupe, $52,900 for the convertible, to $69,000 for the 2007 Corvette Z06. The 2007 Corvette's new features refine a groundbreaking sports car that was all-new in 2005 and substantially enhanced again in 2006. Coupe and Convertible models come with the LS2 6.0L V-8 engine that produces 400 horsepower (298 kW) and 400 lb.-ft. The 2007 Corvette’s power train and suspension, including the 400-horsepower (298 kW) LS2 small-block V-8 engine, are more than adequate to maintain the speed, acceleration and handling required to lead the pack around the famed “Brickyard” race track.
