Chevrolet Corvette C6
LS3 6.2L V8 Engine:
The 6.2 Liter LS3 V8 − standard in coupe and convertible − produces an SAE-certified 430 horsepower at 5900 rpm and 424 lb.-ft. of torque at 4600 rpm. Power output is even higher with the available dual-mode exhaust system with 436 hp at 5900 rpm and 428 lb.-ft. of torque at 4600 rpm. Yet the engine achieves a remarkable EPA estimated MPG 16 city, 26 highway with the standard six-speed manual transmission. Even with its impressive performance, the engine does not incur a federal government gas-guzzler penalty.
