There's a 380bhp 5.0-litre V8 and a 503bhp supercharged version, both driving through a six-speed automatic gearbox. The standard engine delivers scorching performance but the supercharged version is simply staggering. Although mere figures can't begin to convey the intensity of the forces unleashed when you crush the accelerator to the floor, we can tell you that blasting from 0-60mph in the coupe takes just 4.6 seconds, and its 50-70mph time is only 1.9 seconds. Get the picture?

The XK rides like a grand tourer, even on the optional 19- or 20-inch wheels, but it changes direction and grips the road like a sports car. It's firm, but nicely damped, and the optional active suspension gives superb control. The steering weights up nicely in bends and the brakes are excellent. The XKR has a firmer ride, but it's still comfortable.

You'll love the V8 gurgle and growl, though it disappears when cruising. Less welcome is the tyre noise on coarse roads. The automatic gearchanges are smooth, though you notice them a bit more when braking hard with the gearbox in its sport setting.

This is an expensive car and it has running costs to match. So, whether bought privately or as a company car, it will cost you for the privilege of ownership - but then you wouldn't even be contemplating it if you couldn't afford it. Depreciation losses over three years could be as much as £30,000.

Jaguar's quality and reliability have both been impressive in recent years, and the XK’s cabin feels solidly built. Most of the materials are classy and appealing too, although some of the minor controls have a rather lightweight feel.

The XK has a pyrotechnically triggered bonnet lid, which pops up to protect pedestrians in the event of a crash. It's the only way Jaguar could retain a sleek, low nose while providing decent protection to people on foot. The expected active and passive safety features are all present and correct, and Jaguar security is usually very good.

The XK's driving position is excellent and electric adjustment for the seat and steering wheel makes it easy to get comfy. It’s a shame, then, that the seats themselves are rather narrow. The touch-screen centre console minimises clutter, but it can be fiddly and hard to read in strong sunlight. A narrow rear window means that view behind is rather compromised too.

The XK has four seats, but the rear pair are so cramped and awkwardly shaped that it’s best to view them as storage space. There’s plenty of space in the front seats, with enough head-and legroom for tall adults. The hatchback tailgate gives better access than some rivals, but although the boot is long, it’s also rather shallow and narrow.

Leather, satellite-navigation, a six-CD in-dash changer, keyless starting, 10-way electrically adjustable heated seats, Bluetooth phone connectivity, dual-zone climate control and stability control are standard, but you'll probably want to add at least active suspension damping from the extensive options list. The XKR comes with active suspension and metal interior trim.
