Not So Fast! Chevy Could Shorten Nissan’s Nurburgring Celebration

Nissan was so proud of the GT-R‘s production-car lap-record run of 7:29 on the Nürburgring Nordschleife that CEO Carlos Ghosn personally delivered the news to journalists gathered in Portugal.

It must be sweet for Ghosn who championed the GT-R when Nissan was in dire financial trouble. And trumping Chevrolet‘s double-barrel announcements last week regarding the Corvette ZR1‘s outrageous 638-hp output and its 205-mph top speed, doesn’t hurt either.

But wait, didn’t we quote Corvette Chief Engineer Tadge Juechter as saying that the ZR1 “will be able to take the production-car track record at any racetrack”? Yes, we did. What we didn’t mention was that in the same interview, Juechter said that, while the company didn’t yet have a full-production ZR1 to test at Nürburgring’s old track, he confidently predicted the super-Vette would do the deed in “Seven minutes, twenty-something seconds.”

Hey, is that a gauntlet we see there on the ground? Anyone care to pick that up? (We’re looking directly at you, Chevy.)

2009 Chevrolet Corvette ZR1

The official dyno numbers are in: The supercharged 6.2-liter V8 in the forthcoming Chevy Corvette ZR1 cranks out 638 horsepower.

That’s about 20 hp more than the estimates from General Motors’

powertrain gurus when they unveiled the new ZR1 and its monster motor last December.

To simplify the math: The LS9 engine in the ZR1 is rated at 103 hp per liter of displacement, or 1.7 hp per cubic inch (6.2 liters is equal to 376 cubic inches, for the old schoolers in the audience.)

All that power will push the Corvette ZR1, which goes on sale this summer, to a top speed of more than 200 mph, GM says.

What about the grunt? The official number is 604 lb-ft of torque.

The key to that making all the horsepower and torque is a Roots-type supercharger with four-lobe rotors that sits atop the LS9 engine. A liquid-to-air intercooler is integrated into the supercharger’s housing.

The engine will be hand-built at GM’s Performance Build Center in suburban Detroit, the same plant that hand-builds the LS7 V8 used in the Corvette Z06.
