Porsche 911 GT3 review – MPG and running costs
The highly strung engine does like a drink, but not to the extent you might expect
Our time spent in the GT3 fitted with the PDK has included plenty of long drives up and down the British Isles. On paper, manual and PDK models achieve 21.9 and 21.7mpg respectively, but we’ve found it’ll pootle through town and sit at motorway speeds at between 22 and 25mpg, stretching over that if you’re really gentle with the throttle (being stuck in endless roadworks up the M1 also helps).
Start exercising the engine and being naturally aspirated, MPG doesn’t actually deteriorate to the levels you might imagine. You have to be quite committed to hit single figures on the road, something turbocharged rivals the McLaren 765LT and Nissan GT-R will happily dip down into.
Consumables are high, though. Aggressive negative camber and a relatively low wear rating will eat through tyres, regardless if they’re P Zeros or Cup 2s. Protective foils or wraps are also a good idea as the rear quarter panels, particularly, are prone to stone chips thanks to the cambered wheels and cutaway wheelarches.
The good news is that most of the lower trim both front and rear is plastic, not expensive and vulnerable carbon. The nose will scrape without the optional nose lift, but if you do, the exercise won’t be that painful.
