In this episode, Jeremy Clarkson tests two modernised versions of classic Lancias, one a thorough update of the Delta Integrale, the other a completely new take on the legendary Stratos. Meanwhile, James May looks back at the incredible story of the Porsche 917, from its early days as an unpromising widow maker to its evolution into one of the most successful racing cars of all time. Also in this show, Richard Hammond joins Clarkson at Stansted airport as the pair attempt to speed up the journey from check-in to security to the actual aeroplane by devising two radical takes on the idea of motorised hand luggage.

In the final episode of the series, Jeremy Clarkson, Richard Hammond and James May present a short and informative history class on one of the bedrocks of British life; the medium-sized Ford saloon. Starting with the Cortina of the 1960s and ‘70s, the three chart the history of the car that changed British society and provided transport for millions of dads including Clarkson senior and father May though not, to his annoyance, Richard's dad. To cover the ‘80s part of this documentary, Richard takes to the track in the legendary Sierra RS Cosworth before all three hosts re-group to celebrate the Ford Mondeo and this model's unique claim to fame. Since the Mondeo seems certain to cease production without replacement in the coming years, the history lesson ends with a touching memorial service to this totem of British life.
