2015 Corvette will be GM's most powerful car ever at 650 HP

2015 Corvette will not only be the most powerful street-legal production car ever produced by General Motors; the 650 HP and 650 lb-ft of torque also puts the 2015 Corvette Z06 in the company of cars costing hundreds of thousands of dollars more.

The 2015 Chevrolet Corvette Z06 convertible is unveiled at the New York International Auto Show in New York in April.

When Chevrolet took the wraps off the 2015 Chevrolet Corvette Z06 earlier in the year, it promised power output of at least 625 horsepower and 635 pound-feet of torque. Mission accomplished. The final production figures for the Z06’s supercharged LT4 V-8 are in, and the car will lay down blistering numbers to the tune of 650 hp and 650 lb-ft of torque.

These official ratings not only make it the most powerful street-legal production car ever produced by General Motors, it also puts the 2015 Corvette Z06 in the company of cars costing hundreds of thousands of dollars more. Based on the infographic below released by Chevrolet, the list of current production cars that outmuscle the 2015 Z06 is a short one. It includes the LaFerrari, McLaren P1, Porsche 918, Ferrari F12 Berlinetta, Lamborghini Aventador and the Ferrari FF. That’s some impressive company for the Corvette to be associated with.

Even though pricing has yet to be announced for the 2015 Chevrolet Corvette Z06, the cars with more horsepower range in price from around $300,000 to well over $1 million. On this list, only the 640-hp SRT Viper is priced less than $200,000, which is where the Z06 will be positioned.

As much horsepower as 2015 Chevrolet Corvette Z06 produces, its torque specs are equally impressive. The 650 lb-ft will peak at just 3,600 rpm, and Chevrolet says that over 90 percent of the torque (592 lb-ft) will be available from 2,500 rpm up through 5,400 rpm. For optimal off-the-line acceleration, the engine will produce 457 lb-ft at a low “just off idle” rpm.

The 2015 Z06's stats compare pretty well to the outgoing ZR1, too: the '15 Z06 has 46 lb-ft more torque and an additional 12 hp.

Chevrolet has not released performance or top speed figures for the 2015 Z06, but when it goes on sale toward the end of this year, it’s undoubtedly going to be difficult to catch.
