DETROIT — The 2015 Chevrolet Corvette Z06 is rated at 650 horsepower and 650 pound-feet of torque, making it the most powerful production car ever from General Motors.
The official performance numbers were released on Friday.
The 2015 Corvette Z06 goes on sale in the fourth quarter of 2014. Pricing has not been announced.
The horsepower number is a significant one, since Chevrolet was determined to deliver as much output — or more — with the Z06's new LT4 supercharged 6.2-liter V8 engine as it did with the outgoing 2013 Corvette ZR1. The ZR1's LS9 engine delivers 638 hp and 604 lb-ft of torque.
"The new LT4 engine builds on the design strengths of our previous supercharged engine and leverages the technologies introduced on the Corvette Stingray — direct injection, cylinder deactivation and continuously variable valve timing — to take Corvette performance to an all-new plateau," said Jordan Lee, GM chief engineer for small block engines, in a statement.
He added: "It's also worth mentioning that the LT4's supercar performance numbers are achieved with an engine that is nearly the same size as the very compact LT1 engine introduced in the 2014 Corvette Stingray. The power density of the LT4 makes it one of the smallest and lightest 650-hp engines in the industry."
The engine is mated to a standard seven-speed manual transmission or the new eight-speed automatic transmission.
In comparison, the 2014 SRT Viper and Viper GTS are equipped with an 8.4-liter V10 engine that produces 640 hp and 600 lb-ft of torque. The 2014 Ford Shelby GT500 is powered by a 5.8-liter supercharged V8 engine that churns out 662 hp and 631 lb-ft of torque.
"The V12-powered Ferrari F12 Berlinetta produces about 28 percent less torque than the Z06, despite offering about 12 percent more horsepower," GM said.
It noted: "The new LT4 engine eclipses the Porsche 911 Turbo S engine's peak power levels by 90 hp."
Edmunds says: The 2015 Chevrolet Corvette Z06 delivers a staggering 650 hp — something that car shoppers with lofty power aspirations will appreciate.
