From the article:
Engine-wise, a Plug-in Hybrid variant could be in the charts, but nothing has been confirmed as of yet. The new three-liter twin-turbocharged V6 may come in two variants, replacing the ML 350 with a ML 400 model and introducing a new ML 450 version.

The ML 400 will make due with 333 hp and 480 Nm (354 lb ft) of torque, while the not-yet-confirmed ML 450 will get the 367 hp and 550 Nm (406 lb ft) of torque version of the new powerplant that will also arrive on the Mercedes-Benz C 450 Sport. Expect more details about the facelifted SUV as we learn about them.

What's wrong with its bumper?

It's a preproduction unit and cameo'd to disguise it somewhat.

NSA edition... those are sat. dishes in the fenders that let them listen to peoples cell phone convos as they drive around.

LOL, 1+ yes I believe that what it is.

On a serious note... I do notice the defined exhaust ports.

Haha... I meant the rear bumper looks like sh*t! Like it was wrecked already...

Good thing they covered up the star in the grille in those 10 other pictures... now no one knows its a Benz ML!
