Z before G: Chevrolet Corvette ZR1 clips the Nissan GT-R's Nürburgring lap time

General Motors has announced that its Chevrolet Corvette ZR1 has navigated Germany's famed Nürburgring in 7 minutes 26.4 seconds - besting the mighty Nissan GT-R by nearly three seconds (7:29). The Corvette ZR1 set the blistering mark earlier this morning, piloted by GM development engineer Jim Mero.

The announcement was made today by Tadge J. Juechter, the Corvette's Chief Engineer, on the GMNext blog.

Although the mark of 7 minutes 26.4 seconds is amazingly fast, Mero said that he thought he could shaved a couple tics off that mark. Conditions for the run were good, although there was a stiff headwind down the main straight away.

The Corvette ZR1 that set the mark was completely stock, including a tank full of pump gas.

With the ZR1 besting the GT-R's mark, the gloves are probably officially off. Both Lexus and Acura have vowed that their upcoming supercars - the LF-A and NSX, respectively - will trump the GT-R, but the Japanese automakers will now have to set their sights on the most potent Chevrolet ever created. Moreover, Nissan is developing an even more high-performance V-Spec version of the GT-R, which could potentially trump the ZR1's 7:26.4 lap time.
