The all-new six-part series sees Chris Evans and Matt LeBlanc joined by Sabine Schmitz, Chris Harris, Eddie Jordan and Rory Reid. Their mission? To test the world's finest cars to the limit... and beyond. Series 23 sees the 'Top Gear' team ferrying superstar musicians to the top of Africa in 4x4s, journeying across Britain in roofless three-wheelers, and battling off-road baddies in a car made of scaffolding. It also features tests of the latest, greatest supercars from Ferrari, Aston, McLaren and more. And, of course, the return of Top Gear's enigma wrapped in a riddle wrapped in a race suit: The Stig.
