Driving Character: Porsche 911 GT2 RS vs Porsche 911 Turbo S
The Porsche 911 GT2 RS is an apex predator, utilizing its 700hp twin-turbo flat-six to deliver performance that borders on the extreme. With power sent solely to the rear wheels, the chassis requires significant driver skill to manage, especially during corner exit. The aerodynamic setup creates immense downforce, pinning the car to the road at high speeds. Gear changes are executed with violent efficiency, and the steering is razor-sharp, responding to the slightest input. It is a car that demands total respect, offering an analogue, raw experience that is increasingly rare in modern, computer-managed high-performance machinery.
The Porsche 911 Turbo S utilises a sophisticated AWD system with active torque vectoring that provides staggering, all-weather performance.

Ingress and egress are hampered by the roll cage and rigid bucket seats, making this less of an errand-runner and more of a track-day specialist. The ride is punishingly firm, communicating every bump directly to the driver’s spine. While the luggage space is adequate for a small bag, it is not designed for grand touring. Owners accept these compromises as part of the price for one of the most powerful rear-wheel-drive road cars ever built.
