Currently reading: Road test rewind: Porsche 911 GT2 RS
It was the fastest, stiffest, most powerful and widest road-going 911 Porsche had built

2017 saw Porsche's 991-generation 911 recieve the GT2 treatment. Here's what we made of it at the time: 

The new Porsche 911 GT2 RS becomes the latest in a line of five ‘GT2’ namesakes, the first of which appeared in 1995 as a homologation version of the 993-generation 911. That original version’s 444bhp would hardly worry a modern super-sports car driver, although it still earned itself the legendary nickname ‘Widowmaker’.

The 691bhp 3.8-litre flat six in this car is a development of Porsche the current 911 Turbo engine (with 80bhp more than the last 3.6-litre GT2 had) and uses bigger turbochargers, new pistons and water-sprayed charge air intercoolers. It is the first GT2 with a paddle-shift dual-clutch gearbox and is steered by the same four-wheel system as was used in the 918 Spyder.

The GT2 RS’s standard-fit fixed-backrest bucket seats and half-sized roll-cage build your sense of anticipation nicely for the driving experience to come. The seats are comfortable over longish distances, not feeling narrow in the cushion or restrictive. You get a fine driving position that, while not as low or inboard as a mid-engined supercar might offer, still makes you feel close to the rotational axis of the car and provides good visibility.

The paddle-shift gearbox delivers a typically effective launch control mode, but it also has a ‘paddle neutral’ function that allows you to disengage the clutch whenever you want to, and to fully control the timing of its re-engagement manually as you prefer.

The car’s power is appealingly linear through the middle of the rev range. Even though the quickest £200k mid-engined options are a shade quicker in outright terms, the GT2 RS feels very rapid indeed. Throttle response is as remarkable as its outright accelerative potency so you get no sudden rush of mid-range torque as the engine comes on boost, and the car feels less thuggish at full power than you might expect.

It seems wider on the road than other 911s, but still narrower than most cars of its performance level. Outright grip level is formidable at normal road speeds and body control reassuringly close and taut. There’s a shade more steering kickback and restlessness about the car’s ride than a GT3 might have as you press on, though, and a sense of rebalanced grip levels that favour stability more than in other GT-department 911s and that can blunt driver appeal at certain times and speeds. It doesn’t blunt the car’s handling balance much at all at track speeds, mind you.

Back to top


The GT2 RS is a spectacular driver’s car but it isn’t quite the ultimate GT derivative: a GT3 has more absorbing handling and an engine you’d treasure for longer. This is the proof, however glorious, that the 911 strays narrowly out of its depth when it tries to beat hardcore supercars at their own game.

When we tested the GT2 RS, the Lamborghini Huracán Performante held the Autocar lap record at MIRA’s Dunlop circuit, with 1min 5.3sec. That an unambiguously rear-engined machine might topple the Lambo seemed unlikely but there was a feeling that if anyone could, Porsche could.

And they might have, had the car been shod in Michelin’s fragile and horrendously dear but wondrously sticky Cup 2 R rubber, which was just starting to emerge on the option lists of the hardest of hardcore supercars. Instead, on the ‘regular’ Cup 2 tyres, the GT2 RS managed a still-rapid 1min 7.8sec – and demonstrated an unparalleled ability to totally overwhelm Michelin’s excellent track-day tyres.

In fact, the manner in which it chomped through the grip provided by not only 325-section rear tyres but also the competition-spec rear wing – prompting the rear axle to spit wide even through the quickest, 125mph corner on the circuit – is imprinted in my memory. With Cup 2 R rubber, the GT2 RS might have been tidier and may even have beaten the Lambo.

As it was, the car felt like it needed taming. Just like a GT2 RS should.

Richard joined Autocar in 2017, arriving from Evo magazine, and is typically found either behind a keyboard or steering wheel.

As deputy road test editor he delivers in-depth road tests, performance benchmarking and supercar lap-times, plus feature-length comparison stories between rival cars. He can also be found on Autocar's YouTube channel

Mostly interested in how cars feel on the road – the sensations and emotions they can evoke – Richard drives around 150 newly launched makes and models every year, and focuses mainly on the more driver-orientated products, as is tradition at Autocar. His job is then to put the reader firmly in the driver's seat. 

Away from work, but remaining on the subject of cars, Richard owns an eight-valve Integrale, loves watching sportscar racing, and holds a post-grad in transport engineering.
