2017 Mercedes-Benz G-Class

For the 2017 model year, a new G550 4x4 joins the Mercedes-Benz family of SUVs. It is the most capable G-Class ever, boasting innovative portal axles, three locking differentials, a ground clearance of more than 17 inches and a 4.0L Biturbo V-8.

Since development of the G-Class began in 1972, the military -- turned passenger -- vehicle has been hand-built in Graz, Austria. The G550 4x4 joins the already-robust G-Class lineup, which features the 416-hp G550, the 563-hp AMG G63, and the 621-hp AMG G65, notably featuring a 6.0-liter V12 Biturbo engine producing a massive 738 lb-ft of torque.

The ladder-type frame found in the G-Class provides the ideal platform for the immense capability afforded by the 2017 G550 4x4. Constructed of steel, the frame requires over 6,400 individual welds to be fully assembled before it is dip-primed and powder-coated. All interior cavities of the frame are then treated with a hot wax for added protection against water, snow, salt and sand.

The frame of the G-Class provides a robust platform that is better suited for off-road use than a unibody, offering ideal protection for the fuel tank, exhaust system and drivetrain if the vehicle bottoms out on an off-road obstacle. When driving on articulating surfaces, the ladder-type frame prevents the body from twisting forces, which could severely damage a more conventional unibody.

Featuring a 4.0-liter Biturbo V8, the G550 4x4 produces 416 hp and 450 lb-ft of torque for exemplary on-and-off-road performance. Power is transferred to all four wheels by way of a 7G-TRONIC PLUS seven-speed automatic transmission.

The exterior design of the G-Class has become an icon in the automotive design landscape. While the 2017 G550 retains the classic G-Class shape, it boasts an even more intimidating appearance with its extraordinary ground clearance and wide track width.
