The M911 is powered by an eight-cylinder two-stroke Detroit Diesel 8V92TA diesel engine rated at 324.4 kW. With a gross vehicle weight of 26,000 kg and a kerb weight of 16,550 kg, around 9,450 kg remains for payload or towed load. A length of 9,370 mm, a wheelbase of 6,750 mm and eight wheels across multiple axles point to a vehicle built for heavy towing duty.
At a gross weight of 26,000 kg, the M911 belongs to EU class N3, the heavy commercial vehicles above 12 tonnes. The Detroit Diesel 8V92TA is a two-stroke engine, a design that differs from today's common four-stroke diesels and was known for high output per litre in a compact size.
When buying an M911, the condition of the two-stroke diesel engine matters particularly, since its servicing – oil consumption and cylinder liner lubrication, for instance – differs from four-stroke engines. The frame, axles and towing gear should be carefully checked for wear and cracks given the high loads involved in towing. The air suspension and braking system also deserve a thorough check at this weight, as do the seals on the numerous axles and the condition of the coupling used for towed loads.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
