This 911 GT2 RS comparison reveals how different the 997 and 991 really are

Born from Porsche’s need to homologate its cars for GT2 class racing, the 911 GT2 debuted in 1993, when it was based on the 993-generation 911. A twin-turbo flat-six model since day one, the GT2 was updated to 996 specs in 2001 and then to 997 specs in 2007. In 2010, Porsche came up with an even more aggressive version, the GT2 RS. Rated at 612 horsepower and 516 pound-feet of torque, it was Porsche most powerful car for the 2011 model. A follow up came in 2018 with the 991-generation, this time around with 690 horses and 553 pound-feet of torque on tap. However, the 991 GT2 RS lost the manual transmission. The latter is by far the most impressive GT2 RS built to date, but is it actually much better than the 997 model?

To find out if the 991 GT2 is better than the 997 GT2, the folks over at PCAHQ brought together a pair of 911 GT2 RS models and tested them on both the road and the track

. Both cars are impressively fast, but the comparison reveals that they behave significantly different. This is far from surprising, though. The 991 model not only employs more technology, but it also features an automatic PDK transmission. The 997 comes with a manual and not as many driving assist systems, so it’s more of a driver’s car.

The driver concludes that "the old car does something that new cars don’t do," referring to a more exciting and connected experience. The 997 GT2 RS delivers brute force, and it’s the better car if you want the authentic Porsche experience. The 991 is the more robotic version of the GT2 RS. The PDK lets you focus on driving and makes everything so much easier, but it also feels a lot faster, despite having only 78 extra horsepower. Which one is better? Well, it depends on what you want from your 911 GT2 RS.
