The C6 Corvette, which debuted in the 2005 model year with the 6.0L LS2 engine (400 horsepower), is scheduled to get an upgrade, possibly in the 2008 model year, to the new 6.2L LS3 engine.

The C6 Corvette

The LS3 is based off the L92 truck motor that debuted in the 2006 Cadillac Escalade and Chevrolet Tahoe. The LS3's cylinder heads are very similar to the 7.0L LS7 heads found on the 505 horsepower Z06 Corvette, except they are designed for smaller cylinder bores. In addition to the heads, the LS3 included a cam phaser, which allows variable valve timing to maximize horsepower while not sacrificing low end torque or economy.

It is unclear at this time if the LS3 will receive Active Fuel Management, the cylinder deactivation technology that is used in the L92 to inrease higway fuel economy 10%. Many enthusiasts are concerned the Corvette will sound like a four-cylinder when AFM is engaged.
