1979-1983 Peugeot 604 2.3 TD (80 Hp)

The Peugeot 604 2.3 TD, produced between 1979 and 1983, represents a significant offering in Peugeot’s flagship saloon range. Positioned as a more economical alternative to the petrol-powered versions, the 2.3 TD utilized a turbocharged diesel engine to deliver reasonable performance with improved fuel efficiency, a growing priority for European motorists in the late 1970s and early 1980s. This variant occupied a middle ground within the 604 lineup, offering a balance between the base models and the more powerful, higher-trim level options. It was primarily aimed at drivers covering long distances, such as sales representatives or those frequently travelling across Europe, where fuel costs were a major consideration.

Technical Specifications

Powertrain & Engine Architecture

The heart of the 604 2.3 TD is the XD2S 147 engine, a 2.3-liter inline-four diesel. This engine was a development of Peugeot’s earlier diesel designs, incorporating a turbocharger to boost power output. The XD2S featured indirect injection, utilizing a pre-chamber combustion system. This system involved a small auxiliary combustion chamber connected to the main cylinder, where fuel was initially injected and ignited. The resulting flame then propagated to the main cylinder, promoting more complete combustion and reducing engine noise – a common characteristic of diesels at the time. The turbocharger, a Garrett unit, provided approximately 7.5 psi of boost, increasing power and torque significantly compared to naturally aspirated diesel engines of the era. The engine employed a Bosch mechanical fuel injection pump, carefully calibrated to deliver the correct amount of fuel under varying load conditions. While not particularly high-revving, the XD2S produced a respectable 80 horsepower at 3,600 rpm and approximately 144 lb-ft of torque. The engine was typically paired with a three-speed automatic transmission, although a five-speed manual gearbox was also available, albeit less common in this configuration.

Driving Characteristics

The 604 2.3 TD Automatic offered a distinctly different driving experience compared to its petrol-powered siblings or the manual diesel versions. The three-speed automatic transmission, while providing convenience, wasn’t particularly sophisticated by modern standards. Gear changes were relatively slow and noticeable, and the transmission lacked the responsiveness of more modern automatics. Acceleration was adequate for cruising, but overtaking required careful planning. The turbocharger did provide a noticeable surge of power once it spooled up, but this was often accompanied by some turbo lag. The engine’s torque characteristics meant that it was more suited to relaxed, long-distance driving than spirited performance. The 604’s comfortable suspension and relatively quiet cabin (for a diesel) made it a pleasant vehicle for covering large distances. However, the added weight of the diesel engine and automatic transmission did impact handling somewhat, making it feel less agile than the lighter petrol models. Fuel economy was a key selling point, typically achieving around 28-32 mpg on the highway, a significant improvement over the petrol engines.

Equipment & Trim Levels

The 604 2.3 TD typically came equipped with a reasonable level of standard features, reflecting its position as a premium saloon. Standard equipment generally included power-assisted steering, central locking, electric windows in the front doors, and a velour upholstery. The dashboard layout was typically wood-veneered, giving the interior a sophisticated appearance. Optional extras included air conditioning, a sunroof, leather upholstery, and upgraded audio systems. The 2.3 TD trim level often sat between the base models and the more luxurious V6 variants. While it didn’t offer the same level of opulence as the V6, it provided a comfortable and well-equipped interior suitable for discerning buyers. The exterior trim was generally understated, with chrome accents and relatively conservative styling.

Chassis & Braking

The Peugeot 604 utilized a robust chassis featuring independent suspension all around. The front suspension employed MacPherson struts with anti-roll bar, while the rear suspension utilized a trailing arm setup with coil springs and an anti-roll bar. This suspension configuration provided a comfortable ride and good handling characteristics. Braking on the 604 2.3 TD typically consisted of disc brakes on the front wheels and drum brakes on the rear wheels. Power assistance was standard, providing adequate stopping power for most driving conditions. The steering was a recirculating ball system, offering a relatively heavy but precise feel. The chassis was designed to accommodate the heavier diesel engine and automatic transmission, with reinforced components where necessary.

Market Reception & Comparison

The Peugeot 604 2.3 TD was generally well-received by critics as a practical and economical luxury saloon. It was praised for its comfortable ride, spacious interior, and fuel efficiency. However, some critics noted the lack of performance compared to the petrol models and the somewhat dated automatic transmission. Compared to the 604 2.8 V6, the 2.3 TD offered significantly better fuel economy but lacked the V6’s refinement and power. Against the 2.0-liter petrol versions, the 2.3 TD provided more torque and better fuel economy, but at the expense of acceleration. The 2.3 TD was often seen as a sensible choice for drivers prioritizing economy and comfort over outright performance. Reliability was generally good, although the indirect injection system could require occasional maintenance.

Legacy

The Peugeot 604 2.3 TD, while not the most iconic version of the 604, remains a respected and relatively sought-after classic car. The XD2S engine proved to be durable and reliable, and many examples are still on the road today. The 604, in general, is remembered as a stylish and well-engineered saloon that represented Peugeot’s ambition to compete with the best European manufacturers. The 2.3 TD variant, in particular, is appreciated by enthusiasts for its fuel efficiency and comfortable long-distance cruising capabilities. In the used car market, well-maintained examples of the 604 2.3 TD can command reasonable prices, particularly those with low mileage and a complete service history. The car represents a unique blend of 1970s and 1980s technology, offering a glimpse into a time when diesel engines were becoming increasingly popular as a fuel-efficient alternative to petrol.
