Nissan on Porsche's GT-R lap time criticism: go to driving school

by Drew Johnson

While 0-60 and quarter-mile times have long stood as the measuring stick for any performance car, Germany's Nürburgring is quickly proving to be the new standard for performance testing. Nissan quickly jumped to the head of the Nürburgring class when its GT-R supercar posted a record-setting 7 minute 29 second lap, prompting the GT-R's intended competitor - Porsche - .

Last month, August Achleitner, Porsche's 911 product chief, revealed that Porsche had purchased a Nissan GT-R, but could not muster a lap time better than 7:54 around the "˜Ring. After studying the test results, Achleitner concluded that the GT-R that set the Nürburgring lap record "could not have been a regular series production car", and must have been wearing non-production semi-slick racing tires.

It's no surprise that Nissan took Achleitner's remarks as an insult, and has since replied with its own assessment of the situation.

Nissan is adamant that the 7:29 GT-R was rolling on stock rubber -- Dunlop SP SPORT 600 DSST CTT - and even openly invited anyone to go see the record-setting tires for themselves at Sumitomo Rubber Industries in Japan. Nissan also welcomed the chance to give any automaker a driving lesson in the GT-R to demonstrate its full capabilities, insinuating that Porsche's driver had no idea how to properly handle the GT-R. "We are aware that several auto makers have purchased the GT-R for their own testing and evaluation," the Japanese automaker said in a statement. "We would welcome the opportunity to help any auto manufacturer with understanding the full capabilities of the GT-R."

With top bragging rights on the line, we doubt is the last we'll hear on the subject from Porsche or Nissan.
