Volvo 16 84R

The same system explains its siblings: FM is the forward-control truck with the medium-height cab, FL the one with the low cab. FMX adds an X for Xtreme to the M and means the reinforced version for heavy terrain. Read those four abbreviations once and the whole Volvo range falls into place without opening a data sheet.

Older vehicles carry a number after the abbreviation: FH12, FH16. It gives displacement in litres, not output. An FH16 therefore has a sixteen-litre engine. Newer listings usually put the power in horsepower there instead — FH 460, FH 500. Both notations circulate side by side; confusing them turns a twelve-litre engine into a twelve-horsepower vehicle or the reverse.

The FH has been in the range since 1993 and has been fundamentally renewed several times. More than three decades separate an early FH12 from a current FH. The designation alone says nothing about that — first registration and emissions standard are the dependable figures.

More important for the purchase than the letters is the axle configuration. 4x2 means four wheels, two of them driven; 6x2 adds an axle without drive, 6x4 has two driven rear axles. Anyone facing heavy trailer loads or unmade roads finds the answer there, not in the cab letter.
