Peugeot 604 classic cars for sale

History of the Peugeot 604

When Peugeot introduced the 604 at the 1975 Geneva Motor Show, it marked the manufacturer's ambitious return to the executive car segment, which Peugeot had not entered since the 1930s Peugeot 601. Developed at Peugeot's Bavans technical centre, the 604 was built on the Peugeot 504's architecture, targeting customers seeking a car with traditional yet sophisticated lines. Its understated styling by Pininfarina ensured a dignified appearance; its use for official state functions, including the Élysée Palace, and by figures like Erich Honecker, underlines its status. Production continued in France until 1985 with an additional assembly by Kia in South Korea between 1979 and 1981. Over 153,000 units were built before the 604 was succeeded by the Peugeot 505 and 605.

Model History of the Peugeot 604

The 604 was the successor to the Peugeot 601 and signalled Peugeot’s move upmarket in the mid-1970s. Early models featured the new PRV V6 petrol engine, and Peugeot continuously developed the car during its production run. Notably, the 604 served as a blueprint for later luxury sedans in Peugeot’s line-up, and its eventual successors, the 505 and later the 605, further established Peugeot’s position in the executive segment. Additionally, rare long-wheelbase versions were crafted by French coachbuilder Heuliez for official government use.

Highlights and Unique Features of the Peugeot 604

The most prominent feature of the 604 is the PRV V6 engine, the result of a collaboration between Peugeot, Renault, and Volvo. Initially conceived as a V8 but reduced due to the 1970s oil crisis, the resulting 90-degree V6 configuration delivered smooth performance and up to 136 PS, later reaching 114 kW in the highest trims. The car’s elegant exterior lines, by Pininfarina, and high-grade interior comfort placed it in the same league as premium saloons from Germany and Italy. The 604 was also available with advanced features such as Bosch K-Jetronic fuel injection and automatic transmissions.

Special Editions and Collectible Models

Among the rarest Peugeot 604 variants are the long-wheelbase Landaulet versions by Heuliez, both measuring 5.34 metres and used as state limousines by French presidents. These editions are especially notable for their exclusivity and their symbolic status in French political history.

Weak Spots and Common Issues

The most significant technical challenge faced by the Peugeot 604 was its susceptibility to rust, particularly in early production years. Regular inspection of sills, wheel arches, floor panels, and door bottoms is recommended. Mechanically, maintaining the PRV V6 engine requires attention to the timing gear and fuel injection systems, especially in the K-Jetronic-equipped models. Parts availability for bodywork and interior components can pose occasional difficulty due to the car's rarity today.

Engine, Transmission, and Handling

The Peugeot 604’s PRV V6 engine offers refined, smooth operation, while later diesel options provided improved efficiency, making it a popular choice for fleet and government use. The well-balanced chassis, tried-and-tested from the 504, delivers a comfortable and predictable drive typical of French luxury cars in the late 20th century. The manual five-speed transmission added in later models contributed to a more engaging driving experience. Braking and steering systems are both engineered for ease – prioritising comfort for longer journeys. Key variants worth special mention include:

• 604 TI (144 PS, fuel-injected)
• Diesel versions (notable for reliability and efficiency)
• Heuliez Landaulet (long-wheelbase, state use)

Interior, Comfort, Exterior and Design

The Peugeot 604’s understated yet elegant exterior was styled by Pininfarina, with smooth, clear lines that remain instantly recognisable. Inside, luxury is defined by high-quality material choices and generous space for all passengers. Special features included plush upholstery, wood trim, and an array of period-appropriate optional equipment, such as air conditioning and electric windows. The saloon was sometimes specified in unique colours and configurations for government or ceremonial customers, with the Landaulet versions offering a truly special presence.

Other Noteworthy Features

The 604 not only played a diplomatic role but also paved the way for international collaborations: its PRV engine partnership is a notable example in automotive history. Assembly in South Korea by Kia marked Peugeot's early steps into global expansion, a rarity among European marques of the time.

Summary

With its combination of distinguished Pininfarina styling, advanced Franco-Swedish engineering, and cultural significance as an official state car, the Peugeot 604 offers a distinctive option for classic car buyers seeking French executive luxury from the 1970s and 1980s. Potential owners should be aware of maintenance requirements, especially regarding rust, but will be rewarded with a car that represents a unique chapter in European automotive history.
