Jaguar XKR-S GT 2012-2014 review

In engineering terms, it would certainly appear to be the real deal. Although the 5.0-litre supercharged V8 engine and six-speed automatic is unchanged from the regular XKR-S (the engine produces identical outputs of 542bhp and 502lb ft), there is much that is new beneath the GT’s more flamboyant exterior. Gone are the rear seats, replaced by a full roll cage. The front seats are lighter and far more supportive racing buckets, both with a full four-point harness seatbelt. But it’s the chassis and suspension – and the brakes – that have received the greatest attention.

In essence, the GT would appear to be a kind of rolling test bed for most of the good stuff that will eventually make its way into the hottest versions of the F-type coupé. The rear axle is new, much of the front suspension hardware has been replaced (and will appear in the F-type), the front track is a whopping 52mm wider (although the rear track remains unchanged) while the uprights, springs and dampers will each, in various forms, make their way into future quick Jaguars.

The brake discs are carbon ceramic, with huge 398mm rotors at the front and 380mm at the rear, thereby addressing one of the key criticisms of the regular XKR-S – that it can’t quite stop as well as it can go. Which is always a touch concerning when there’s one and three quarter tonnes of car to keep in check, although in this case the kerb weight has dropped by 40kg to a still hefty 1713kg.

Bottom line; the XKR-S GT doesn’t just stop better than the car on which it’s based, it’s also nearly 70 per cent stiffer at the front and 25 per cent stiffer at the back. Couple this with the wider front track, a set of fatter, stickier Pirelli P-Zero Corsa tyres (255 section front, 305 rear) and some 145kg of downforce courtesy of that big rear wing and some additional new winglets at the front, and what you end up with – in theory – is a very different animal indeed from the already quite wild XKR-S. 

A car that can lap the Nürburgring, indeed, in some 7min 40sec, which is about where the original version of the current Nissan GT-R was when it tore the rest of the world – including the Nordschleife – to shreds not that many years ago.

If nothing else, the XKR-S GT’s 0-60mph time goes a reasonable way towards justifying its price on its own, at an impressively scant 3.9sec. What we are talking about here is a car with a surfeit of performance, in other words. A machine whose potential you might not ever exploit fully on the public road.

And yet, as it turns out, the GT is actually a rather pleasant car to drive on a public road, with a surprisingly compliant ride, lovely steering feel, not too much noise from its vast rear tyres despite the removal of those rear seats, and a far more civilised personality in general than you’d expect, given the way it looks.

On the road it feels stiffer and more controlled than the regular RS; there would be something strange going on were this not the case. But despite the extra control and the new-found absence of roll or lurch when changing direction quickly, it doesn’t feel compromised in terms of its ride quality. 

It’s firmer than normal, yes, but it still feels like a Jaguar on the move over a typical UK B-road. The compromise it strikes here is more successful than that of the recent XFR-S, it must be noted, which, to be blunt, is almost too stiff for everyday road use.

Secondary observations on the road; it really does steer beautifully; on a dry surface the Corsas stick like the proverbial you-know-what to a blanket; the gearbox can never quite make its mind up which ratio it wants to be in, even if you select “sport” mode which, in theory, should mean it holds on to whatever gear you select manually.

The noise that erupts out of the four tailpipes if you give it full beans beyond 3000rpm is 110 per cent outrageous – to a point where pedestrians dive for cover, literally, if you are heartless enough to keep your toe in as you howl past.

Conclusion; on the road (preferably a dry one, although even on wet surfaces it proved to be a lot less of a handful than we expected) the Jaguar XKR-S GT is, well, something of a revelation truth be told. 

You look at its wings and skirts and its ultra low ride height, then read the specification sheet and discover that it’s two times stiffer than normal, and think; this is going to be an unbearably uncomfortable, totally uncompromising, mostly unnecessary way to spend £135,000 on a Jaguar and give yourself a huge dentistry bill in the process. 

But what you discover is, despite appearances, a really rather lovely car to drive. Not a Porsche 911 GT3 rival but, instead, something almost as quick and a fair bit more usable into the bargain.
