Just how far can you push a modern 4WD? In this new, specially commissioned, programme from Duke, we seek out the most extreme off-road action in the UK and show you how the experts do it. . There’s a fascinating visit to the Bowler factory where some of the most powerful Land Rovers in the world are created. There’s loads of tips about prepping a vehicle for an off-road rally and then hold on for our onboard camera blast with the Bowler test driver! We also spend an action-packed day at Eastnor Castle – the home of Land Rover testing. Plus there’s a 4WD off-road challenge event over mixed terrain in mid-Wales, a 4WD Safari event at Sweet Lamb and a mixture of Greenlaning and Trials from the Isle of Man 4WD club when we join them on their annual 150mile Mule event. Mud-plugging a plenty! Finally we include a feature on the British Armed Forces Land Rover Rally Team, following them on the gruelling Manx International Rally (Round 6 of BRC) with some entertaining in-car footage.
