This 1999 report covers a detailed design benchmarking study of the Peugeot V6 3.0-litre gasoline engine and includes a photographic record of all the main components, plus individual masses and dimensions. Ricardo comments on specific design features are also included.
Renault and PSA Peugeot Citroen combined to design a new V6 engine with a 60 degree bank angle for introduction in the 1997 model year, to replace the older Peugeot 90 degree V6 engine. The group made a joint investment of £173 million. The engine is manufactured at the Francais de Mecanique factory in Douvrin with a target production rate of 360 engines per day.
The engine has an all-aluminium construction, with the main bearing housing in the form of a ladder frame. Refinement has been a key feature, and is enhanced with an apparently stiff engine structure, iron inserts in the ladder frame, and hydraulic tappets. The timing drive has a single toothed belt.
Maximum power of this engine is 140kW (190hp) at 5500rpm with a maximum torque of 267Nm at 4000rpm.
