Like the C5, the Corvette C6's suspension consisted of independent unequal-length double wishbones with transverse fiberglass mono-leaf springs and optional magnetorheological dampers.

This boosts the EPA's derived fuel economy, allowing the buyer to avoid paying the "gas guzzler" tax.

In addition to the larger displacement engine, the Corvette Z06 has a dry sump oiling system, and connecting rods made out of titanium alloy.

Other weight saving measures such as balsa wood/carbon fiber composite floors and a magnesium alloy engine cradle were used.

[15] Additionally, it was only available in exterior colors Inferno Orange and Supersonic Blue, and the interior was decked out unique Z06 Carbon emblem accents.

[16] The ZR1 is the high performance variant of the Z06 and was first reported by several print and online publications, based on rumors that General Motors was developing a production version of the Corvette above the Z06 level under the internal code name Blue Devil (named after CEO Rick Wagoner's alma mater, Duke University).

The car was originally rumored to feature a supercharged LS9 engine having a power output of more than 630 hp (639 PS; 470 kW).

[17] The October 12, 2006 issue of AutoWeek published photos by photographer Chris Doane of a C6 Z06 with special auto-manufacturer-issued license plates with a hood bulge, widely thought to confirm the presence of a supercharger on the Blue Devil.

The car had manufacturer's license plates, carbon-ceramic disc brakes, enlarged fender vents, a hood bulge, and an engine with a positive-displacement supercharger in the valley between the cylinder banks and a water-to-air intercooler atop it.

[20] Motor Trend confirmed the official name for the production version of the Blue Devil, resurrecting the old ZR1 nameplate.

[21] General Motors officially introduced the Corvette ZR1 on December 19, giving a press release and photographs of the car.

Magnetic Selective Ride Control was also included on the car, with sensors to automatically adjust stiffness levels based on road conditions and vehicle movement.

Notable exterior features include special Arctic White paint, red grand sport style stripes on the front fenders and red and silver hash styled stripes incorporating a maple leaf similar to the livery present on the winning car.

[26] The ZHZ was a standard Corvette equipped with the LS3 engine, 6-speed automatic transmission, vacuum actuated valve exhaust, F55 suspension and unique 7-spoke chrome wheels.

Models wear the same velocity yellow "45U" body hue that adorns the C6.R or "41U" gloss black, along with a "Jake" graphic that spans the Championship edition's hood.

A body-colored spoiler shared with the ZR1 joins a "carbon pattern" engine cover, while a leather-wrapped ebony interior contains "GT1" embroidered on the head rests of the seats, the instrument panel and a center console armrest.

[31] Order code "ZLC" was an equipment package celebrating 100 years of Chevrolet racing heritage.

Offered exclusively in Carbon Flash Metallic, the Centennial Edition kit includes satin-black graphics and unique lightweight cast-spun aluminum Centennial Satin Black wheels that feature a thin red perimeter outline (on Z06 and ZR1 cars).

The Z06X, introduced in 2010,[34] featured racecar components such as: carbon fiber adjustable rear wing, carbon fiber front splitter, full roll cage, fire suppression system, race seat, harness, carbon ceramic brakes, upgraded cooling system, polycarbonate rear window, adjustable coilovers, adjustable sway bars, and tow hooks; the radio, interior carpeting and sound-deadening materials have been removed.

[36] The C6.R was a replacement for the C5-R, built by Pratt & Miller, and unveiled for its first competition at the 2005 12 Hours of Sebring endurance race of the American Le Mans Series.

In addition to the American Le Mans Series, Corvette C6.Rs also race in the FIA GT1 World Championship.

Riley Technologies built a GT2-class Chevrolet Corvette for the 2008 American Le Mans Series.

These include a stripped interior, full rollcage for safety, center-locking wheels, carbon fiber doors, rear deck spoiler and front splitter.

[38] In an effort to achieve parity among the disparate participants of the GT3 Series, three forms of handicapping were applied by the FIA regulators: additional vehicle weight, ride height, and tire compound selection.
