2009 Chevrolet Corvette Pictures, Specifications, Information

After a milestone year in 2008 that saw the introduction of the LS3 6.2L V-8 as the new standard engine, a custom, leather-wrapped interior and more upgrades, the Corvette powers into 2009 with a raft of enhancements that further distinguish it and give customers more choices � including a lower-priced convertible model.

Of course, that range of choices also includes the ZR1, with its 6.2L supercharged engine that produces 638 horsepower (476 kW). (Please see the separate Corvette ZR1 release for complete information on Chevy�s world-class supercar.)

�The Corvette is an American icon with world-class credentials,� said Ed Peper, Chevrolet general manager. �It�s the car we all aspire to own and the 2009 edition, with more choices and features, only amplifies that craving.�

The �09 Corvette lineup includes the Corvette coupe and Corvette convertible, each powered by the 430-horsepower (321 kW) LS3 V-8, and the incomparable Corvette Z06. Equipped with the 505-horsepower (377 kW) LS7 engine and built on a lightweight chassis, the Z06 is a street-going descendent of the championship-winning Corvette racing program.

LS3 Engine

The 6.2L LS3 small-block V-8 is the standard engine in coupe and convertible models. It is rated at 430 horsepower (321 kW)* and 424 lb.-ft. of torque (575 Nm)* with the standard exhaust system. An optional two-mode exhaust system brings a power rating increase to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).

The LS3 features an aluminum cylinder block with cast iron cylinder liners. The cylinder bores measure 4.06 inches (103.25 mm) in diameter and combine with a 3.62-inch (92 mm) stroke to deliver a 376-cubic-inch (6.2L) displacement. Breathing is accomplished via high-flow cylinder heads. They�re based on the large port/large valve design found on the LS7 engine, with larger-capacity, straighter intake ports. The design optimizes intake flow to the combustion chamber and the exhaust ports are also designed for better flow.

Complementing the large-port design of the heads are commensurately sized valves. The intake valve size is a large, 2.16 inches (55 mm). The intake valves feature lightweight hollow stems, which enable the engine�s 6,600-rpm capability. The exhaust valves also are large, measuring 1.60 inches (40.4 mm) in diameter.

To accommodate the engine�s large valves and enable more direct intake port flow, the intake-side rocker arms are offset 6 mm between the valve tip and the push rod. Actuating the valves is a camshaft with 0.551-inch (14 mm) lift.
