It might not look it, but underneath its refined exterior, the Jaguar's newly developed 5-litre supercharged V8 engine, it packs more than enough punch to have even a Ferrari F430 worried. Rory, like a cat with a key to the dairy, gets behind the wheel in our road-test video.
Fast as it is though, you'll probably not be going anywhere very quickly if you live in London. It's a good job then, that the interior plays host to gadgets galore, including an 18cm (7-inch) touchscreen entertainment system that lets you watch digital Freeview TV, listen to DAB radio, access music via an iPod or USB stick, and play the whole shebang via a 7.1-channel Dolby Pro Logic II audio system from Bowers & Wilkins.
Watch the video to see the XFR strut its stuff, and then pay oura visit for an in-depth look at the inside of this elegant monster.
Update: In the video, Rory said an unrestricted version of the XFR did 255mph in Utah. This was slightly exaggerating its monstrous power: it did 225mph. Apologies for the error.
