Text+Video: 2009 Corvette ZR1 Breaks Nissan GT-R's Lap Record

Corvette Chief Engineer, Tadge J. Juechter has official broken the news of the upcoming 2009 Corvette ZR1 posting the fastest ever production car lap time around the Nurburgring. ZR1 now beats the 2009 Nissan GT-R's impressive record of 7:29 with its faster laptime of 7:26.4, as verified by the onboard datalogging and two hand-held stopwatches.

Here's what Juechter wrote on GMNext blog: "This morning (Friday June 27), General Motors development engineer Jim Mero drove the Corvette ZR1 around the Nürburgring in a time of 7:26.4. Jim commented after the lap that conditions were good except for a strong headwind down the main straight and that the lap was solid, but he felt there were a few places he could have gone faster." Now this indicate towards GM's intention of further improving the lap time and thus make things more difficult for upcoming 2011 Honda/Acura NSX and Toyota LF-A.

Giving out further details, Juechter clarified that the ZR1 that lapped the Ring was instock trim with no change in engine calibrations and it wore the production cars Michelin Pilot Sport 2’s tires. The chassis alignment and vehicle height were set to factory specs and the fuel used was the standard pump (not racing) gas. The only additional devices used were the communications and safety equipment.

To put an end to all possible speculation, Juechter wrote: "The vehicle was exactly like the cars that will be built in Bowling Green, Kentucky and sold around the world later this summer."

An in-car official video will be posted in the week of July 7 when the ZR1 engineering team returns from Germany. But rather waiting till then you can checkout BridgeToGantry's short spy video below that gives you glimpses of the 2009 Corvette ZR1 lapping the Ring.
