Matt Smith on Top Gear

Matt Smith will be a guest on tonight's episode of Top Gear, taking part in the 'reasonably priced car' and following in the footsteps of Christopher Eccleston, Billie Piper and David Tennant.

Jeremy Clarkson and James May pay tribute to quirky and recently deceased Swedish car maker Saab.

Richard Hammond races a rocket-powered flying man against a rally-spec Skoda and Jeremy smokes around the track in the Maserati Gran Turismo MC Stradale and the tyre shredding Mercedes C63 Black.

Plus current Doctor Who Matt Smith is the star in the reasonably priced car.

The episode airs tonight at 8.00pm on BBC Two.
