Inside Line puts the 2002 Corvette Z06, the 2010 Corvette Grand Sport and the 2011 Corvette Carbon Prototype to a head to head test on the IL test track and the Streets of Willow.

We had no choice but to head to the track.
This 2011 Chevrolet Corvette Z06 Carbon is a hand-built prototype assembled from a 2010 Corvette Z06 and a big box of parts, so it couldn't be driven on public roads. It even came to us in a trailer complete with its own bodyguard from Chevrolet. So our only option was pretty much a track experience on the test asphalt at Auto Club Speedway and the winding road course at the Streets of Willow. Poor us.

Just to get a little perspective on the state of all things Corvette, we included the 2010 Chevrolet Corvette Grand Sport, which has all the things that we like about the Z06 Vette and none of the things we don't. And just as a baseline, we fronted up our 2002 Chevrolet Corvette Z06, a plain, $20,000 used C5 Vette that will kick rocks at just about any other car on the road.

The things we do for science.
Z07 + CFZ = Carbon (Almost)
Some 500 lucky people will take delivery this fall of a 505-horsepower 2011 Chevrolet Corvette Z06 Carbon, and while the cars won't carry unique VINs (which will compromise their collectability a bit), they will be very special.

Even if you're not in the lucky dog club, you can nearly duplicate the Carbon by ordering a 2011 Corvette Z06 with the $9,495 Z07 Performance package, which includes active suspension, staggered 19- and 20-inch wheels, Michelin Pilot Sport PS2 tires and Brembo carbon-ceramic brakes. And if you want to make it look right, you could add the $3,995 CFZ Appearance package, which includes a front aero splitter, rocker skirts, roof and ZR1-style spoiler (all made from carbon fiber). Adding just these stand-alone options to a 2011 Z06's base MSRP of $75,255 means you could build your almost-Carbon Z06 for just $88,745.

GM tells us that the prix fixe or a la carte carbonized versions of the track-ready Z06 will have MSRPs below that of the supercharged Corvette ZR1. We asked GM representatives if adding a $30,000 premium to the Z06's base price would be about right for a Carbon — say, $105,255 altogether. They'd only say that the Corvette Z06 Carbon will be priced above the standard 2011 Corvette Z06's $75,255 and below the 2011 ZR1's $110,750.
