In 1980, both front and rear bumper covers were restyled with brand new integrated aerodynamic spoilers that resulted in a significant reduction in drag and increased radiator air flow. The hood was also restyled as well. The crossed-flag emblems disappeared from the front fenders and were revised to a more elongated style on the nose and fuel door. L-82 emblems moved from the hood to the front fenders on cars ordered with the optional high performance engine. This was the finale for the L-82 Corvette emblem, now producing 230 hp (172 kW) but it could not be mated to a 4-speed, as the manual gearbox was offered only with the L48 engine option. The speedometer in all cars read to a maximum of 85 mph (137 km/h), mandated by a new and controversial federal law. Air conditioning became standard, as did the tilt-telescopic steering column, power windows, exterior sport mirrors, and the convenience group. New was an optional roof panel carrier that would mount to the rear fastback deck.
