The Saviem SM was a range of medium trucks produced by the French manufacturer
Saviem between 1967 and 1975.
History
At the end of 1967, as part of an extended partnership with the German
MAN,
Saviem introduced the SM (Saviem-MAN) ranges.
They were made up of the namesake SM medium truck range using the 812
cab, derived from the cab used for the SG range (
Super Galion and
Super Goélette),
and the heavier
SM Europe range using the Europe/Espace cab. The commercial versions of the SM were discontinued in 1975, although versions for military use were still produced after that year.

Variants
The SM range line-up included the SM5 (8.7-tonne

Engines
All the SM range (except for the SM5) initially used the 597 engine manufactured at Saviem's Limoges plant, and later its evolutions: the 797 and the 798. The 597 was introduced in 1967, and it was also used for trucks of the MAN's medium range. It was a 5.27-litre

direct injection technology and was only used on the SM6 and some military vehicles from 1970 onwards. In 1970, the SM range mounted the 797 and 798 (also called 597-05 and 598) engines, derived from the 597. The 797 (introduced in 1970) was a 5.49-litre atmospheric straight-six engine with a power output (at launch) of at 2,900 rpm and a torque of at 1,700 rpm. The 797 was used in the SM7 and SM8 models. The 798 (used only on some versions of the
Saviem SM8 4x4) was similar to the 797, but it was

The SM5 used an evolution of the 712-01 engine used on the SG range.

Suspension and brakes
The suspension of the range had leaf springs on both axles. Brakes were hydraulic/ air brakes (SM6) and compressed air brakes (SM7 and SM8).[
