Mercedes-Benz E400d All-Terrain Coming This Year With S-Class’ Straight-Six Diesel

The Mercedes-Benz E-Class All-Terrain will celebrate its second anniversary in September. However, the high-riding executive estate is still not available with a powerful diesel engine.

But that’s about to change, according to MercedesBenzPassionBlog, as the three-pointed star’s Audi A6 Allroad and Volvo V90 Cross Country challenger will welcome a new powertrain in Q3.

The twin-turbo 2.9-liter inline-six is entirely new, and already powers the E400d, S400d and new CLS 400d. It delivers an identical output of 340PS (335hp / 250kW) and 700Nm (516lb-ft) of torque in all three cars.

This should be a welcomed departure from the current 194PS (191hp / 143kW) 2.0-liter four-cylinder mill used in the E220d, or the E350d, with its 3.0-liter V6 that generates 258PS (254hp / 189kW).

Both models have a standard dual-clutch nine-speed automatic gearbox, which will be the sole transmission offered in the E400d (name unconfirmed), too, according to an initial announcement made by the automaker.

Just like the rest of the high-riding E-Class lineup, the new E400d will keep its rugged design with generous plastic cladding and a jacked-up suspension. The latter allows it to sit 39mm (1.5in) higher than the standard Estate, and provides it with a ground clearance of up to 156mm (6.1in).

The most extreme version of the Mercedes-Benz E-Class All-Terrain adds the 4×4² suffix, and was created by a company engineer. It benefits from even more ground clearance, achieved by fitting a pair of portal axles taken from the G500 4×4².
