2010 Porsche 911 GT3 Posts 7m 40s Time on Nurburgring

A new season of ‘Ring wars may be brewing. Porsche's Project Manager for High Performance Cars Andreas Preuninger says the latest 911 GT3 has achieved a time of 7 minutes 40 seconds around the Nurburgring's Nordschleife.

2010 Porsche 911 GT3Porsche test driver Walter Rohrl, who was piloting the car, was apparently slowed down by the presence of other vehicles on the track. Had Rohrl really been going for it "with a knife between his teeth" said Preuninger, his time would have come down by as much as two seconds. Furthermore Rohrl apparently did a 7 minute 45 seconds in a borrowed Ferrari F430 Scuderia. The time was achieved under the same conditions as the GT3.

As for the Nissan GT-R, Preuninger noted that Porsche's official line is that the 7 minute 54 second time it achieved with a US-spec unit in 2008 stands. Nissan said in May 2008 that the GT-R did a 7 minute 29.03 seconds at the German track in the hands of its chief test driver Tochio Suzuki. The updated 2010 GT-R is claimed to have done an even quicker time of 7 minutes 27.56 seconds.

The third member of this feuding trio is the Corvette ZR1 which has a posted time of 7 minutes 26.4 seconds at the Green Hell. Preuninger's remarks on the ‘Vette were only to say it's a cool car but it serves a different purpose than the GT3.

The new updated 2010 Porsche 911 GT3 was unveiled at the 2009 Geneva Motor Show. Its normally aspirated 3.8-litre boxer engine produces 435hp (320kW) and peak torque of 317 ft-lbs (430Nm).

2008 Porsche 911 GT3 Cup

(from Porsche Press Release) New 420 bhp Porsche 911 GT3 Cup Stuttgart. The new Porsche 911 GT3 Cup is entering the 2008 motorsport season with engine output increased to 420 bhp. The car will be raced in the Porsche Mobil1 Supercup, the world’s fastest international brand trophy, and worldwide in national Porsche Carrera Cups and GT3 Cup Challenges. 265 units of this production-based racing car developed in Weissach will be built on Porsche’s production line in Stuttgart-Zuffenhausen, marking a new record for a car of this category.

2008 Porsche 911 GT3 Cup2008 Porsche 911 GT3 Cup-2The most significant modification compared with last year’s model is the new rear end following the design of the production model. Air venting slits ensure better dissipation of heat at the rear. The 3.6-litre six-cylinder boxer engine developed in Weissach is also based on the street-legal GT3 and develops maximum output of 420 bhp, 20 horsepower more than on the previous model. The sequential six-speed transmission with interruption of engine power enables the driver to shift up under full throttle without disengaging the clutch. The transmission itself has been optimised and the gear ratios adjusted to the characteristics of the engine. Weighing 1,150 kg in race trim, the new 911 GT3 Cup has a power-to-weight ratio of 2.7 kg per horsepower.
