Saviem S

The S range was introduced in 1964 and originally consisted of two models using the 710 cab: the Saviems S5 (5-tonne payload) and S7 (7-tonne payload).[2] Later, Saviem expanded the range, unveiling two new models at the 1964 Paris Motor Show: the S8 (8-tonne payload) and the S9 (9-tonne payload).[3] In 1966, the company introduced the S6 (6-tonne payload).[4] The S range was replaced in 1967 by the SM range, although evolutions of the S5 (S5B and C)[5] and the S9 were still produced afterwards. FAR converted S trucks, the resulting models being called SD (SD5, SD8).[6]

The S5 is powered by the 591 engine, a 3-litre four-cylinder diesel with a maximum power output of 75 PS (74 bhp; 55 kW) at 3,200 rpm and a torque of 180 N⋅m (130 lb⋅ft) at 2,000 rpm.[6] The S6, S7 and S8 are powered by the Perkins 6.354,[4] a 5.8-litre six-cylinder diesel with direct injection which delivered a maximum power output of 126 PS (124 bhp; 93 kW) at 2,800 rpm and a torque of 392 N⋅m (289 lb⋅ft) at 1,600 rpm.[7] The suspension of the four trucks have leaf springs on both axles. Brakes are hydraulic (S5) and air brakes (S7 and S8).They have a five-speed "synchromesh" manual gearbox and a gammer worm and roller steering system.[6]

The S9, a model based on the 840 JL truck range cab, is powered by the F 646 Fulgur engine, a 6.8-litre six-cylinder diesel delivering 150 PS (150 bhp; 110 kW) at 1,500 rpm and a torque of 422 N⋅m (311 lb⋅ft) at 1,650 rpm. The truck has a six-speed "synchromesh" manual gearbox. As the other S models, the S9 has a leaf spring suspension and a gammer worm and roller steering. Its wheelbases are between 3,000 mm (120 in) and 4,600 mm (180 in).[8]
