The Peugeot 604 was the French marque’s flagship executive sedan, launched in 1975 and remembered for its elegant Pininfarina styling, long wheelbase comfort and distinctive European touring character. For Australian enthusiasts, the 604 offers a compelling blend of understated luxury and mechanical individuality, with its supple ride quality, spacious cabin and rear wheel drive layout making it feel quite different from many contemporary sedans. Early models used the PRV V6 engine, a unit jointly developed by Peugeot, Renault and Volvo, while later diesel variants helped cement Peugeot’s reputation for long distance efficiency and durability.

Although never a mass market success, the Peugeot 604 gained cultural significance as a discreet transport choice for diplomats, senior officials and executives who preferred refinement without flashiness. It was also one of the first European luxury cars to offer a turbo diesel engine, an important step in making diesel power acceptable in premium passenger vehicles. Today, keeping a 604 in top condition often comes down to choosing quality service parts, suspension components, braking parts, filters, ignition items, fluids and accessories that suit its unique engineering.
