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."Here is a rundown of the new features and content changes for the '09 Corvette lineup: Corvette 1LT convertible -- Customers can slip into a Corvette convertible for a lower MSRP with this 1LT-equipped model. Additionally, a power top is now standard on 2LT convertible models. Two new exterior colors -- Cyber Gray Metallic and Blade Silver Metallic are added, while Machine Silver Metallic is discontinued. This brings the Corvette's exterior palette to nine colors. Revised crossed flags emblem -- The iconic Corvette crossed flags emblem is distinguished with a new, bright surround. Two new custom leather-wrapped interiors -- Dark Titanium and Ebony join Sienna and Linen as available selections. Bluetooth capability -- This option enables the Corvette to offer the convenience and safety of Bluetooth hands-free phone service. Standard power hatch pull-down -- This convenient feature is now standard on Corvette coupe and Z06 models. Additionally, steering wheel audio controls and variable-ratio steering are standard on all models. Revisions also are incorporated to the hardware and software of the anti-locking braking, traction control and Magnetic Ride Control systems. Several trim and content changes are incorporated on the Z06, too. They include: - New, "spider"-design 10-spoke Z06 wheel available in four versions: Sparkle Silver, Competition Gray and chrome - Color-keyed door and instrument panels with red and titanium interiors - Power-operated pull-down hatch now standard - Gray stitching on Ebony base seats (previously red) - New door sill plates with the Z06 logo - Acoustic package standard on all Z06 models - The Z06 also receives a larger-capacity dry-sump oiling system. It upgrades to the 10.5-quart (9.9 liters) system of the new ZR1. The previous oil system held eight quarts (7.5 liters). The popular museum delivery option (RPO R8C) remains available for all Corvette models. 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.
