The Peugeot 604 2.8 GTI, produced between 1983 and 1985, represented the performance pinnacle of the 604 range. Positioned as the flagship model, it offered a significant step up in power and driving experience compared to the lower-spec 1.6 and 2.0 liter versions. The 604 itself was Peugeot’s large, executive car, intended to replace the aging 504, and was produced from 1975 to 1985. The 2.8 GTI variant aimed to compete with established German rivals like the BMW 5 Series and Mercedes-Benz E-Class, offering a blend of French comfort and respectable performance. It was primarily sold in Europe, with limited exports to other markets.

Powertrain & Engine Architecture
The heart of the 604 2.8 GTI is the ZNJ 154A engine, a 2.8-liter (2849 cc) V6. This engine is a naturally aspirated, gasoline-fueled unit featuring a 9:1 compression ratio and two valves per cylinder. It utilized Bosch multi-port fuel injection, a relatively advanced system for the early 1980s, contributing to improved fuel efficiency and smoother power delivery compared to carbureted engines. The engine produced 150 horsepower at 5650 rpm and 235 Nm (173 lb-ft) of torque at 3000 rpm. The engine’s longitudinal mounting and rear-wheel drive configuration were a deliberate choice, aiming for a more balanced and engaging driving experience. The 5-speed manual transmission was the only gearbox option for this model, designed to handle the engine’s output and provide precise control.
Driving Characteristics
The 604 2.8 GTI offered a noticeable improvement in performance over the lower-displacement models. Acceleration from 0 to 60 mph took around 11.2 seconds, and it could reach a top speed of 115 mph. While not a sports car by modern standards, it provided brisk acceleration and comfortable cruising. The rear-wheel drive layout contributed to a balanced feel, although the car’s weight (approximately 3200 lbs) was still apparent in cornering. The 5-speed manual transmission allowed drivers to keep the engine in its optimal power band, maximizing performance. Compared to the 2.0-liter versions, the 2.8 GTI felt significantly more powerful and responsive, making it a more enjoyable car for long journeys and spirited driving. The gear ratios were well-chosen for both acceleration and highway cruising.
Equipment & Trim Levels
The 2.8 GTI was the most well-equipped version of the 604. Standard features included power steering, ventilated front disc brakes, and comfortable cloth upholstery. Leather upholstery, air conditioning, and a sunroof were common optional extras. The interior was generally well-appointed for its time, with a focus on comfort and practicality. The dashboard layout was functional, with clear instrumentation. The GTI trim also featured unique badging and often came with alloy wheels, distinguishing it from the more basic models.
Chassis & Braking
The 604 featured an independent McPherson strut front suspension and a coil spring rear suspension. This setup provided a comfortable ride, absorbing bumps and imperfections in the road effectively. The GTI model benefited from slightly stiffer springs and dampers compared to the standard 604, improving handling and reducing body roll. The braking system consisted of ventilated discs at the front and solid discs at the rear, providing adequate stopping power for the car’s weight and performance. Hydraulic power steering was standard, making the car easier to maneuver at low speeds.
Market Reception & Comparison
The Peugeot 604 2.8 GTI was generally well-received by automotive critics, who praised its comfortable ride, spacious interior, and refined engine. However, it was often criticized for its relatively high price and its somewhat dated design compared to its German rivals. Fuel economy was also a concern, with combined fuel consumption averaging around 20 mpg. Compared to the 2.0-liter versions, the 2.8 GTI offered a significant performance upgrade but came at a higher cost, both in terms of purchase price and fuel consumption. The 2.8 GTI was positioned as a more luxurious and powerful alternative to the more economical 2.0-liter models.
Legacy
The Peugeot 604 2.8 GTI, while not a massive sales success, remains a fondly remembered classic among enthusiasts. The ZNJ 154A V6 engine is known for its durability and smooth operation, although maintenance can be costly due to its age and complexity. Finding parts can also be challenging. Today, well-maintained examples of the 604 2.8 GTI are becoming increasingly collectible, appealing to those who appreciate classic French engineering and a comfortable, refined driving experience. The car represents a high point in Peugeot’s history, showcasing the company’s ability to produce a sophisticated and capable executive car.
