2002 Z06 Corvette

CHEVROLET BUILDS THE QUICKEST Z06 CORVETTE EVER AT 405 HP,
AND REFINES COUPE AND CONVERTIBLE

"At 405 horsepower, the LS6 will match the highest peak power level
of the legendary 5.7-liter DOHC LT5, which powered the ZR1 Corvette."

-----Dave Hill Chief Corvette Engineer

 

 

For nearly 50 years, the Corvette has had a special place in America’s garage. Crafted from a precise blend of power, performance, style and comfort, Corvette’s success has been based on a willingness to embrace advancing technology while remaining true to its heritage. Today’s Corvette exemplifies this philosophy like no other.

More power

Last year’s introduction of the Z06 Corvette, based on the former hardtop model and the legendary 1960s Z06 option package, is aimed at true performance enthusiasts at the upper end of the high-performance market. And now, an extra boost of 20 hp, to 405, makes Z06 the quickest production Corvette ever.

The Z06 will continue to be outfitted with the unique six-speed manual transmission for 2002. It will enable skilled drivers to achieve 0-60 mph times of 3.9 seconds and to cover a quarter mile in 12.4 seconds at 116 mph. By comparison, the 2001 powertrain combination achieved 0-60 mph in 4.0 seconds and the quarter mile in 12.6 seconds at 114 mph.

This upgrade to the LS6 engine’s output is the result of new hollow stem valves, a higher-lift camshaft, a low restriction mass air flow (MAF) sensor and a new low restriction air cleaner design. Eliminating the PUP converter from the exhaust system enables better flow of spent gasses and reduces vehicle weight, without compromising Corvette’s NLEV (National Low Emission Vehicle) status.

To withstand the greater torque output of the new engine, the LS6 clutch was redesigned. Clamp load has been increased seven percent and durability has been augmented by the following enhancements:

The clutch-driven disc was redesigned, with the flange plate thickness increased by 20 percent - from 5 mm to 6 mm The damper springs were redesigned to increase wind-up rate, from 33 Newton-meter degrees to 35 Newton-meter degrees Premium alloy steel wire is now used for the damper springs

These changes ensure long life and good performance for the LS6 clutch.

Suspension upgrades

The Z06-specific FE4 High-Performance suspension system features a larger front stabilizer bar, a stiffer rear leaf spring and specific camber settings – all calibrated for maximum control during high-speed operation. The 2002 Z06 also has new rear shock valving for a more controlled ride.

Although retaining the same design and color finish, the unique aluminum Z06 wheels are now produced using a cast rather than a forged process. The magnesium wheel option for Coupes and Convertibles is no longer available.

Maximum agility

The foundation of Corvette’s agile handling is hydroformed frame rails. Its four-wheel independent front suspension features cast aluminum upper and lower A-arms. The Z06 and models equipped with the available Z51 package now have aluminum front stabilizer bar links for lighter weight. The rear suspension has a transverse leaf spring system.

All Corvettes have the second-generation Active Handling system as standard equipment. The system features dynamic rear brake proportioning to prevent rear wheel lockup, and rear brake stability control to assist the driver in maintaining control under light braking and high acceleration conditions. It also has integral traction control calibrated to allow drivers to experience the Corvette’s power and handling while controlling excessive wheelspin. The system’s on/off switch and "Competitive Mode" enables drivers to disengage the traction control feature without giving up Active Handling’s other benefits.

 

Additional refinements

Now standard on Z06, the Corvette’s Head-Up Display (HUD) projects vehicle speed and many other gauges digitally on the windshield ahead of the steering wheel, enabling drivers to keep their eyes on the road. It provides critical vehicle information - including tachometer, vehicle speed, oil pressure, coolant temperature and fuel gauges, among others - promoting a "hands on the wheel, eyes on the road," philosophy.
HUD remains an option on Coupes and Convertibles.

For 2002, the automatic transmission cooler case is constructed of lightweight cast aluminum, replacing the previous stainless steel design.

New high performance front brake pads on Z06 provide improved lining durability and fade resistance in high performance situations.

Coupes and Convertibles receive an AM/FM/In-dash CD system as the new standard entertainment system. An AM/FM/Cassette system is available when buyers order the remote 12-disc CD changer. The 12-disc CD changer is also available with the CD radio.

Corvette’s exterior color palette adds Electron Blue, replacing Navy Blue Metallic previously offered on Coupes and Convertibles. Electron Blue also takes the place of Speedway White as one of five choices on the Z06.
