Mercedes-AMG Petronas driver Sir Lewis Hamilton MBE, takes one of the first opportunities to give the Grenadier 4X4 a no holds barred shakedown on- and off-road, outside INEOS Automotive. INEOS chairman Sir Jim Ratcliffe took the passenger seat as Sir Lewis got behind the wheel. In a video released today, we see the seven-time Formula One World Champion steering the Grenadier across a variety of on- and off-road terrain.
