UPDATE (3/4/18): The original version of this article stated there is no current six-cylinder E-Class All-Terrain available globally, however, an E350d 4Matic is offered in select markets like the UK.
The Mercedes-Benz E-Class All-Terrain has been around for 18 months, but there's still no sign of a larger engine to sit above the current E220d in most markets – though that could be about to change.
The E400d uses a new 3.0-litre straight-six turbo-diesel out of the S-Class, making a healthy 250kW of power and 700Nm of torque – the latter available from just 1200rpm.
In standard Estate form, the all-wheel drive E400d sprints from 0-100km/h in just 5.1 seconds, on its way to a limited top speed of 250km/h. Shifting gears in the low-riding version is a nine-speed automatic.
That's a decent step up from the sole current E220d All-Terrain, which draws 143kW and 400Nm from its 2.0-litre oiler, making for an 8.0-second dash from 0-100km/h and a top speed of 232km/h.
However, in the UK there is an E350d All-Terrain, which draws upon a 3.0-litre V6 turbo-diesel making 190kW and 620Nm – though we're unsure why it isn't available more widely across the European region.
Mbpassionblog claims the new six-cylinder E-Class All-Terrain should be available to order in markets like Europe from the third-quarter of 2018.
