Angry cat loses its head: Jaguar XKR-S convertible at LA Show

Jaguar's XKR-S is the fastest Jag you can currently buy. It's covered in unsubtle vents and sounds like an grumpy giant with a raging hangover. Now, just in time for the LA Motor Show, Jaguar's beheading it and revealing the XKR-S convertible.

It's likely, as is the case with its hard-hatted brother, to be powered by the angriest 542bhp, 502lb ft 5.0-litre supercharged V8 in the world. If you're an engine geek, you'll note that it's got 39bhp and 41lb ft more than the standard XKR.
