Yes, it’s another 911, looking very much the same as they always do. The new 911 GT3 RS was never going to be anything revolutionary, but you can hardly blame Porsche for not wanting to alter the 911 formula that has worked so well for them. You can be fairly sure that a Porsche fan couldn’t care less that a 1963 911S looks almost identical to their latest release the limited edition, 911 GT3 RS 4.0.

Potential owners of the new RS 4.0 are also unlikely to be concerned that it has silly decals, only comes in white and the interior trim seems to have been designed by an unscrupulous youth in a Max Power magazine. None of this matters because the people who buy this car aren’t driving supermodels to the Le Caprice…they’re on the track.

The 4.0litre flat six is heavier than the old 3.8 in the RSR, but weight has been removed by replacing almost everything else in the car with carbon fibre, so the car has a road weight of just 1,360kg despite housing the biggest engine ever put in a 911.

With 500 horses under the bonnet you can expect to see 62mph in 3.9 seconds from a standing start. The RS 4.0 lives up to its racing pedigree on the track, making it round the Nurburgring-Nordschleife in just 7:27 minutes. Not that you would need to know any of these facts and figures to believe that this car is a thoroughbred track eater; the roll cage, seat belt harness and fire extinguisher rather give the game away.
