Next-generation ML-Class will come with substantial changes to the cabin design as seen in the interior spy shot.

Here are the latest spy shots of the upcoming 2012 Mercedes-Benz ML-Class.

This time the prototype spotted here comes with less camouflage revealing much of what will be the car's final styling. The design lines are all very clearly intelligible and we even get a snapshot of the inside with its new and larger display, new instrument panel, and newly positioned gear selector on the steering column.

That all spells out a substantial amount of changes for this next-generation ML-Class which makes sense given how last time we saw Mercedes-Benz engineers benchmarking the car against the Porsche Cayenne and the BMW X5.

Expected to power the new ML-Class will be the 3.0 liter V6 diesel, a 3.5 liter gasoline/petrol V6 and a range-topping 5.5 liter V8.

Mercedes-Benz has also hinted at a new hybrid variant and maybe even a plug-in hybrid too.

The next-generation ML-Class will take its first bow sometime later this year.
