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.
