After trying out the on-road exercises in the first part of Episode J, Marc and Felix leave the asphalt and head off-road at the Mercedes-Benz G-Class Experience Center in Graz. Special experiences await Felix there. Among other things, Felix tackles the water crossing, the infamous Schöckl Trail and a mud bath in the Mercedes-Benz G 500 before he takes on a 100% uphill challenge in the Mercedes-AMG® G 63.
