The Porsche 911 Turbo S utilises a sophisticated AWD system with active torque vectoring that provides staggering, all-weather performance.

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.

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.
