The Chevrolet Corvette (C5) is the fifth generation of the Corvette sports car, produced by the Chevrolet division of General Motors for the 1997 through 2004 model years. Production variants include the high performance Z06. Racing variants include the C5-R, a 24 Hours of Daytona and 24 Hours of Le Mans GTS/GT1 winner. The C5 Corvette was the ...
Although the 1972 model's 350 cu in (5.7 L) horsepower was actually the same as that for the 1971 model year, the lower net horsepower numbers were used instead of gross horsepower. The L48 base engine rating fell to 200 hp (149 kW; 203 PS) SAE and the optional LT1 dropped to 270 hp (201 kW; 274 PS) SAE.
The LS6 was originally only used in the high-performance C5 Corvette Z06 model, with the Cadillac CTS V-Series getting the 400 bhp (298 kW) engine later. The V-Series used the LS6 for two years before being replaced by the LS2 in 2006. For 2006, the Z06 replaced the LS6 with the new LS7.
2003 saw the first challenge to Corvette Racing's two years of dominance in their class. Prodrive chose to enter their Ferrari 550 GTS' in the full ALMS season as well, and although they were not strong early in the season, they managed to win the last four events of the season, including Petit Le Mans.
Not until the debut of the C5 based Z06 in 2001 would Chevrolet have another production Corvette capable of matching the ZR1's performance. Although the ZR1 was extremely quick for its time (0–60 mph (97 km/h) in 4.4 seconds, and onto over 180 mph (290 km/h)), the huge performance of the LT5 engine was matched by its robustness.
The 2025 Chevrolet Corvette ZR1 has been revealed. Its LT7 twin-turbo V-8 makes 1,064 hp and 838 lb-ft. Top speed is at least 215 mph. It goes on sale next year.
The preproduction LT5 initially produced 385 hp (287 kW), but was reduced to 375 hp (280 kW) and 370 lb⋅ft (502 N⋅m) for the 1990-1992 Corvette ZR-1. The power ratings jumped to 405 hp (411 PS; 302 kW) at 5800 rpm and 385 lb⋅ft (522 N⋅m) of torque at 5200 rpm from 1993 until its final year in 1995, [41] thanks to cam timing changes and ...
Consequently, the engines offered very similar performance and resulted in a car whose performance was described by one automotive journalist as "the ultimate in sheer neck-snapping overkill". Typical 2000s-era magazine road tests of Corvettes with the engine yielded 0-60 mph (97 km/h) in 5.6 seconds and 1 ⁄ 4 mile (402 m) in 13.8 second at ...
