Buoyed by their unexpected success in Formula Off Road last series (sixth and seventh best in country, though admittedly the country in question was Iceland), Chris and Freddie head to Mexico to compete in the most gruelling off-road race on the planet: the Baja 1000. A 24-hour, 800-mile non-stop charge over brutal desert terrain. An endurance marathon that tests machine and human to destruction. And beyond. Way beyond.
Elsewhere, there’s a showdown between Renault’s hot Megane Trophy-R, a Porsche Cayman GT4… and an old Lamborghini. Tune in Sunday night, BBC Two at 8pm, or catch up on BBC iPlayer.
