About the Mercedes-Benz GL-Class X166
The X166 generation GL-Class was marketed by Mercedes-Benz as the 'S-Class of off-road vehicles', aiming to provide the refinement and technology of its flagship saloon in a full-size SUV package. The GL 350 BlueTEC features the OM642 V6 diesel engine, which provides substantial low-end torque essential for towing and moving its significant mass with surprising efficiency. Despite its size, the X166 was roughly 100kg lighter than its predecessor and featured advanced Airmatic suspension as standard, offering a remarkably quiet and composed ride. It remains a popular choice for families requiring a genuine seven-seater with high levels of safety and long-distance comfort.
