Jeremy Clarkson, Richard Hammond and James May demonstrate their love for compact, small-engined cars with a trip to Ukraine.With Clarkson in a Volkswagen Up, Hammond in a Ford Fiesta and May in a Dacia Sandero, the trio zoom around the Crimean peninsula absorbing some local history, visiting an old Soviet submarine pen and enjoying their manoeuvrable, economical cars to the full. Unfortunately, their carefree time is curtailed when they are challenged to a vast drive, heading north across one of the largest countries in Europe, and they must take any step necessary to fight the immense boredom of a long car journey.Eventually, the three arrive in Kiev only to receive one final and truly fearsome challenge: to complete their journey they must drive into Chernobyl.Also in this programme, Jeremy is on the track in a very fast and very orange supercar from Denmark, the 1086 horsepower Zenvo ST1.Finally, the Reasonably Priced Car welcomes back singer James Blunt, who talks about his new album and attempting to beat his own lap time out on the track.
