Jaguar XE SV Project 8 review

Importantly, though, the Project 8’s ride isn’t too unyielding for the road. In fact, despite the clanging firmness of those springs, there’s enough compliance and bump absorption to deal with most road surfaces. The damping really is exceptional; it skilfully prevents a firm ride from ever becoming overbearing.

That’s the first surprise. The second is how well-mannered it is in wet conditions. There are a number of high-performance cars out there that would be close to undriveable on Cup 2 tyres in wet weather, but the Project 8 makes them work. There is good turn-in grip and very stable, consistent cornering grip, meaning you don’t feel at all nervous leaning on the chassis in bends. Traction is very strong, too, thanks to the intelligent four-wheel drive system.

What those spring rates guarantee is a very stable and solid platform, a level of body control that no other super-saloon can come close to and astonishingly sharp steering response. There can be no tougher test of a track-focused car than a wet and hideously bumpy back road, but even in those most challenging of conditions the Project 8 gives you the confidence to press on.

On a dry track, meanwhile, it’s clear within two or three corners that this car is unlike any other super-saloon. But of course that's true; no other super-saloon is this aggressive or this expensive. In fact, you very quickly realise that to discuss the Project 8 in super-saloon terms is to somewhat miss the point. It isn’t one. It’s much more akin to a Porsche 911 GT3 RS or BMW M4 GTS. It just happens to have four doors.

The adaptive dampers remain more or less unchanged as you flick between Comfort and Dynamic modes, but in the Track setting they switch to a much more aggressive map. Suddenly, there’s even less roll in the car, far less vertical movement and even tauter responses. On those sticky tyres, the Project 8 finds enormous levels of grip, while the steering is intuitive and uncannily precise. From corner entry and through the apex, the car is perfectly balanced.

In quick fourth gear corners, you feel it rise onto the balls of its feet and sweep through from start to finish in the subtlest four-wheel drift, both axles slipping across the tack surface at the exact same, infinitesimal rate, like an old racing car. It’s one of the sweetest sensations in driving.

Away from a corner, there’s simply no power oversteer. If you unsettle the car on the way in and stand abruptly on the throttle pedal, you can make it drift, but it doesn’t come naturally. It doesn’t slide very willingly even in Track mode, which favours the rear axle right up until the point it starts to lose traction.
