Porsche 911 GT3 RS 4.0 official details Latest RS gets race-bred 4.0-litre engine as power hike and weight savings boost pace
It’s as close as you’ll get to a 911 racer for the road. Porsche has revealed the first images and details of the limited-edition GT3 RS 4.0 – a lightweight, track-focused 911 with 493bhp.

Unlike other GT3 models in the line-up – which use a 
3.8-litre flat-six cylinder engine – the newcomer gets the 
same 4.0-litre powerplant as Porsche’s GT3 RSR racing 
car. It’s the largest motor ever to be fitted to a 911. 

The model is 10kg lighter than the already featherweight GT3 RS, at only 1,360kg, thanks to the use of thin bucket seats, lightweight racing suspension, a carbon fibre bonnet and front wings, plus plastic rear windows. With the additional power – 49bhp more than the GT3 RS – the RS 4.0 promises to shave one-tenth off the 0-62mph sprint time, completing the benchmark in 3.9 seconds. It hits 124mph in 12 seconds.

There are a few extra aerodynamic tweaks, too, including 
a redesigned front bumper which incorporates small turning vanes mounted on either side of the car. These are called ‘flics’, and they help to increase downforce at the front 
end, resulting in improved grip through corners.

Visually, the RS 4.0 is marked out by unique Carrara 
White paint with grey and red detailing, as well as special badging and decals. The stripped-out, lightweight cabin mimics the exterior’s white, red and grey colour scheme. 
The seats are made of Alcantara and leather, while the sat-
nav, radio and air-conditioning are all left out to cut weight. 

Porsche’s Clubsport package, comprising a rollcage, seatbelt harnesses, a fire extinguisher and a battery cut-
off switch, comes as standard; it’s an optional extra on 
the GT3 RS. The RS 4.0 goes on sale in July, priced from £128,466 – that’s around £25,000 more than the GT3 RS.
