How does the 3.0 CDI V6 respond?
Very well. In a vehicle of this weight, the extra mid-range torque means noticeably fewer downshifts when towing or fully loaded.
What is BlueTEC?
It is the Mercedes designation for diesels with SCR aftertreatment using AdBlue. Those versions are covered in our catalogue.
Can I disable the AdBlue system?
Not on public roads: regulations require emissions systems to remain operational. Ask us about your specific case before ordering anything.
