The Volvo FM400 was the go to variant of the FM range for 8 wheeler operation from 2006 to 2010. This means there are plenty of FM400 trucks for sale in the UK used truck market. The trucks are well suited for the export market and there are some that appear as (low powered) tractor units. This was the higher powered options, as truck buyers could also specify their 8×2 or 8×4 Volvo rigid as a 380hp at this time. the FM400 was replaced by the FM410 which itself has been replaced by the FM420.
