Top Gear pounced into action with a Jaguar-themed show. An MP tried out our reasonably priced Liana and everyone drove a Jaguar, or two.

Tory MP Boris Johnson - a man perhaps more famous for his appearances on topical TV quiz show Have I Got News For You than his political work, drove our reasonably priced Liana. His laptime was an unremarkable 1.56, although we're sure he'll spin that to be a good thing. Something about road safety probably.

Jeremy tested the new XJ. The looks haven't changed much, but it's all new underneath - and much better for it. So much better, in fact, that Jeremy kept driving until he ran out of road.

Finally, another Jaguar. We managed to get our hands on a one-off special called the XKR-R. It's a tuned XK with racing suspension, seats, a roll bar and even a stash spot for your helmet. It's a cracking motor that really works, thanks to completely redesigned rear suspension and a limited-slip differential that's more than helpful if you want to step the back end out. Oh, and it does 58mph in first gear.
