Jeremy, James and Richard return for the first episode in another brand new series. Several years on from their epic race across London, the presenters conduct another public service experiment by attempting to find the quickest way to commute across a Russian city. Hammond finds himself in the saddle of a bicycle once again, May lines up in a Renault Twizy and Clarkson makes the case for water-based travel by setting sail in a hovercraft. As usual, the Stig is left to negotiate public transport. Elsewhere, Richard takes the new Lamborghini Huracan for a spin out on the test track, while Ed Sheeran gets to grips with the Reasonably Priced Car.
