On sale late 2012 will (finally) be the ZL1. The convertible will have a supercharged 6.2L LSA engine, worth 580 ponies and 556 lb-ft of torque. Additionally, a stiff one is all the rage: It will have a tower-to-tower brace under the hood, a tranny support reinforcement brace, an X-brace and stiffer cradle as well as V-braces, front and rear respectively, and an underbody tunnel brace. New twin-wire/dual-coil dampers will also make an appearance.
