The new Jaguar XKR-S is another car we spent far too much time ogling at the Geneva show. Special editions of the XKR have appeared before, but this one comes with the "most powerful mass-produced Jaguar ever" tagline.

The eye-popping 542bhp output from the XKR-S's breathed on supercharged V8 almost eclipses the turbocharged V6 Jaguar installed in the XJ220 - impressive when you consider the performance stats of that nineties hypercar.

The new Jag can't manage 0-60mph in 3.8 seconds, but take it from us, it's trouser-tent inducing spectacular in the flesh and the manufacturer claims it's delivered the soundtrack to match.
