The first prototypes of the MAZ-537 were built in 1958 and series production was launched in 1960. The new vehicle incorporated an engine developing 525hp at 2100rpm-a very high figure for that time, even armoured vehicle and tanks had ofer fewer hp-and many significant changes in the fuel supply,cooling system and lubrication which made a complete redesign of the engine compartment covers and louvers necessary. Nearly all components of the frame and chassis were reinforced as well increasing the total weight to 21.6tons (total gross weight 87tons) allowing a load of up to 50 tons to be towed.
