Porsche 911 GT3 RS – MPG and running costs

The RS is built to take serious track abuse, but set aside budget for consumables

Evo rating
RRP
from £192,600
  • Staggering grip and balance; sense of occasion; configurability
  • Feeling its true magic at road speeds can be challenging

Porsche claims that the GT3 RS can achieve 21.4mpg, but expect a figure in the teens when using its performance (as much of it as you can, at least) on the road. Aside from fuel, the RS’s consumables will be the biggest factor in how much it costs to run, particularly if you use it on track.

A set of Michelin Cup 2 front tyres will cost you upwards of £600, and the mammoth 21-inch 335-section rears will cost around £1000 for a pair. Wear through the ceramic brakes and you’ll be looking at a much bigger bill – Surface Transforms offers upgraded and supposedly more durable ceramic discs for over £15k, although these can be resurfaced up to three times for a total lifespan of 10-15,000 track miles. 

That’s a tough pill to swallow, but when you consider that the RS can outperform a lot of purpose-built trackday machinery, the costs involved in running one as a track car sting a little less. And if you have no plans to use it on a circuit, the bills won’t be alarming for anyone that has run a supercar of this calibre before.
