The Chevrolet SSR (Super Sport Roadster) is a retro-styled and retractable hardtop convertible pickup truck manufactured by Chevrolet between 2003 and 2006.
During the 2003 and 2004 model years, the SSR used General Motors' 5.3 L 300 hp (224 kW; 304 PS) Vortec 5300 V8. Performance was 7.7 seconds for 0–60 mph (0–97 km/h) with a 15.9 second 1⁄4 mile (402.3 m) time at 86.4 mph (139.0 km/h).
For the 2005 model year, the SSR used the 390 hp (291 kW; 395 PS) LS2 V8 engine also used in the C6 Corvette, Trailblazer SS, and Pontiac GTO, now offering a manual transmission option, the six-speed Tremec, for the first time. Performance improved dramatically with the LS2; the 6-speed manual version had an advertised 0–60 mph (97 km/h) acceleration time of 5.29 seconds. In addition, GM badges were added to the vehicle.
For 2006, output of the LS2 increased to 395 hp (295 kW; 400 PS).
