The Chevrolet Corvette Convertible enters 2010 with a few changes. While the 430-hp 6.2-litre V8 powers the base model, the optional Grand Sport package adds some track-focused amenities like a dry-sump oil system, rear-mounted battery, differential cooler, a short-throw six-speed manual, stiffer spring and stabilizer bars. Otherwise, the convertible top remains an ease to open, and rigidity isn’t lost with the roof down. Interior is crude compared to rivals, but all the features you’d need are there.
