Our colleagues over at Motor Trend recently took the 2014 Chevrolet Corvette Stingray to the dyno to see how much power the LT1 V-8 engine is putting to the ground. The results were impressive, with the final numbers of 402 horsepower and 400 lb-ft of torque at the wheels effectively confirming the official ratings of the big 6.2-liter V-8, once drivetrain loss is factored in.
The official SAE numbers for the 2014 Chevrolet Corvette are 455 horsepower and 460 lb-ft, with the optional dual-mode exhaust system adding 5 hp and 5 lb-ft for 460 and 465, respectively. MT’s test car was equipped with the seven-speed manual transmission, the Z51 performance package, and the optional exhaust. The test was performed at K&N Engineering in California.
Perhaps the most impressive thing about the LT1 engine is its flexible torque band, which is remarkably even throughout the rev range. As Motor Trend's graphs show, the V-8 produces its maximum torque at 4800 rpm, but the torque curve hits 300 lb-ft starting just above idle at approximately 1600 rpm. Peak horsepower is produced at 5900 rpm.
The 2014 Chevrolet Corvette Stingray’s LT1 powerplant is an advanced version of Chevrolet’s venerable small-block V-8, with technologies like direct injection, cylinder deactivation, and variable valve timing that provide an impressive combination of power and efficiency, as the 2014 Chevrolet Corvette Stingray is rated at up to 29 mpg on the highway by the EPA. The 2014 Chevrolet Corvette Stingray goes on sale later this year for a starting price of $51,995 for the coupe and $56,995 for the convertible, both including destination.
