Volvo FMX: construction truck, engines, transmissions and what to check when buying used
Volvo FMX (from 2010) — Volvo's construction and off-road heavy-duty truck. We look at what sets it apart from the FM, which engines and gearboxes you'll find, and what to check when buying used.
FMX in brief
FMX — Volvo's FM designed for construction and heavy off-road work. It features a reinforced frame, higher ground clearance, strengthened suspension and guards, making it ideal for quarries, construction sites and tough off-road conditions.
The FMX debuted in 2010 and has since been updated. It's most commonly used as a dump truck, concrete mixer, recovery truck or breakdown lorry.
How it differs from the FM
Technically, the FMX is close to the FM but built for heavier loads: higher suspension, stronger frame, and a raised cab for better visibility on site.
The FMX is offered with various axle configurations — 4x2, 6x4, 8x4 and all-wheel drive (e.g., 6x6) — depending on the application. In recent years, an electric FMX version has also been introduced.
Engines and transmissions
The FMX uses Volvo's six-cylinder engines — D11 and D13 (including D13K), in various power outputs, with the most powerful reaching around 540 hp. Euro VI engines are paired with an SCR system using AdBlue.
The transmission is usually Volvo's automated I-Shift, with additional low-range gears (crawler) for construction work. For heavy-duty tasks, there are also manual options, and newer trucks feature Volvo Dynamic Steering or other assist systems.
What to check when buying a used FMX
Inspect the chassis of the truck for cracks, deformations, or signs of welding — especially around the cab mounting and axles. Check the tipping cylinders, hydraulics, hoses, and hydraulic valve if present.
Check the I-Shift gearbox, clutch, and drive shaft: heavy work can quickly wear them out. Start the cold engine yourself: look for smoke, oil leaks, or unusual noises.
Pay attention to the condition of the AdBlue and particulate filter. Check the hour meter readings against service records, as the engine and hydraulics of construction trucks work many hours even when stationary.
Versions
Names and equipment vary by market and year; we list generally described versions, but check the exact specification in the documents of the specific truck.

Frequently asked questions
How does the FMX differ from the FM?
The FMX is designed for construction and heavy-duty work — it features a reinforced frame, higher suspension, and a more robust chassis. The FM is more versatile.
Is the FMX suitable for long-distance trips?
Perhaps, but it's geared towards construction work, so comfort and fuel efficiency aren't as good as the FH.
What should you check when buying an FMX after construction work?
The frame, hydraulics, suspension, and transmission. A clear service history and how the truck was used are very important.
