The 1962 model year was the last Corvette with a solid-rear-axle suspension that was used from the beginning. With two new engines it was also the quickest. Engine displacement increased with the introduction of the 327 cu in (5,360 cc) engine, but dual 4-barrel carburetor engines were no longer available. Hydraulic valve lifters were used in the base 250 hp and optional 300 hp engines, solid lifters in the optional carbureted 340 hp and fuel-injected 360 hp versions. Rocker panel trim was seen for the first time, exposed headlights for the last, until 2005. This was the last Corvette model to offer an optional power convertible top mechanism.
