What is it?
We can forget about part-electric hypercars for a bit because first the Lamborghini Huracán Performante, and now this Porsche 911 GT2 RS, appear to be quicker. At least they are on that section of one-way public road in Germany, and that is what some people seem to care about.
But the Huracán is also the fastest car we’ve put around our own test track, in glamorous Nuneaton, by quite a sizeable margin. This’ll all change, again, of course, one day. But, for the meantime, lose the batteries and motors; internal combustion and light weight is what you need if you just want to go fast.
How fast is the new 911 GT2 RS, exactly? Officially, 6min 47.3sec around the Nürburgring, where we are not testing it; and nor are we at Mira, Nuneaton. Unofficially, however, it’s “f***ing ridiculous”, according to racing driver Richard Attwood, who turns up, unrelated to what we’re doing, at Porsche’s Silverstone experience centre, our base for this test.
If it wasn’t a chance encounter, you suspect Attwood might have been briefed or ushered aside by a Porsche PR person; he hasn’t tried a GT2 RS, but thinks it’s a pretty stupid idea to send 690bhp through only two driven wheels, through Michelin Pilot Sport Cup 2 rubber, and put it on the road to be driven by anybody at all. And he knows a thing or two about ridiculous cars, having won Le Mans in 1970 in a Porsche 917, which probably counts as one.
The counter-argument, though, is that the GT2 RS is supposed to be a bit ridiculous. There are other cars in the 911 line-up that are not. There’s the Turbo, which puts this kind of power through all four wheels and offers the type of driving experience that AMG goes for – relaxed, shovesome, relatively low-effort.
That’s a fairly whopping 118bhp increase over even the Turbo S, via a pair of new, larger turbochargers, a titanium exhaust and a charge-air water cooler, which has a little refillable tank in the boot (at the front) for its water sprays. Porsche says the PDK gearbox has been customised, too, which presumably has something to do with the arrival of 553lb ft of torque. You’d think 182bhp per litre would be one of the laggiest, boostiest things around, but peak torque is made from 2250rpm and stays to 4000rpm, which doesn’t sound that unsensible. We’ll see.
On to the chassis. Blimey. Quite a lot of work has gone on here. There are helper springs on the front (where, as ever, there are MacPherson struts) that allows lighter main springs to be used on the front axle. A similar arrangement was made for the rear on the last GT3 RS – and is again here on the rear, where there is a multi-link set-up.
And there’s more: ride height, camber, toe angle and roll bars can all be tweaked a bit for driving on a race track. Every single chassis joint is a rose joint, which is usually superb for precision and feedback but terrible for refinement. Again, we’ll see.
