The Saviem J was a range of medium-duty trucks manufactured by the French manufacturers Saviem and Renault Véhicules Industriels between 1975 and 1980.
In the early 1970s, DAF, Magirus-Deutz, Volvo and Saviem formed the Club of Four to develop and manufacture a medium-duty truck. In order to do this, the company European Truck Development (ETD) was established in the Netherlands.[1]
The Saviem version of this new truck range, the J, entered into production in 1975 and was fitted with MAN engines assembled under licence at Saviem's Limoges factory.[1] Later, the range incorporated other engines. It went on sale in Britain in 1979, shortly before the name was changed to Renault.[2]
The range was originally composed of three models: JN 90, JP 11 and JP 13, with the latter being subdivided into 13A, B and C.
The JN 90 was a 9-ton GVW (gross vehicle weight) truck with various wheelbases from NaNm (-2,147,483,648feet). The JP 11s were 11-ton GVW models with wheelbases from NaNm (-2,147,483,648feet). The JP 13 had various combinations of engine and dimensions available.[3]
Later, the company introduced the lighter, four-cylinder JK range: JK 60 (6-ton GVW), JK 65 (6.5-ton GVW) and JK 75 (7.5-ton GVW). Wheelbases ranged from NaNm (-2,147,483,648feet).[2] The six-cylinder JN added various version between 7.5 and 8.5-ton GVW.[4] Saviem also introduced the JR/JX range for trucks over 19-ton GVW.
The first engines of the J range were two 5.49L straight-six engines (the 597 and the 598) which had been fitted previously to the Saviems SM7 and SM8. The 597 was an atmospheric with a power output of 1120NaN0 at 2,900 rpm and a torque of 402NaN at 1,700 rpm. The 598 was turbocharged and had a maximum power output of 1270NaN0 and a torque of 454NaN.[3] The JK range added the 720 straight-four MAN-licensed engines, producing 90hp at 3,000 rpm and 172lbft at 1,680 rpm.[4] [5]
A single gearbox, the S 5.35 type from ZF, was used on all the range. It was a fully synchronized five-speed unit.[3] Later were incorporated the S 5.25 (for the JK models) and a Saviem-made unit.[6]
The J range had a suspension of leaf springs with dampers and anti-roll bars at the front and rear.[3] The steering is a worm and sector setup.[5]
