The Peugeot 104 Coupe 1.4, producing 72 horsepower, was a stylish and economical coupe produced between 1979 and 1984. It represented a more sporting and refined iteration of the popular Peugeot 104, which itself was a significant model for the French automaker, built upon the A82 platform. The Coupe aimed to offer a more individualistic alternative to the standard 104 saloon (sedan) and estate, appealing to buyers seeking a compact, fuel-efficient, and relatively affordable coupe. This variant occupied a middle ground within the 104 Coupe range, positioned below the later 1.6-liter versions but offering a step up in perceived sophistication compared to the base 104 saloon.
Peugeot 104 Coupe 1.4: An Overview
The 104 Coupe, launched in 1979, was a two-door coupe derivative of the existing 104 hatchback and saloon. It featured a more streamlined silhouette, a more comprehensively equipped interior, and a generally more upscale feel than its more utilitarian siblings. The 1.4-liter engine variant, designated with the engine code XY6B, was a key part of the initial lineup, offering a balance between performance and fuel economy. The Coupe was intended to broaden the 104’s appeal, attracting buyers who desired a small, practical car with a touch of flair. Production continued until 1984, when the 104 range was gradually phased out.
Powertrain & Engine Architecture
The heart of the Peugeot 104 Coupe 1.4 was the XY6B engine, a 1377cc inline-four cylinder petrol (gasoline) engine. This engine was a naturally aspirated unit, meaning it did not employ a turbocharger or supercharger. It featured a single overhead camshaft (SOHC) valvetrain, operating two valves per cylinder. The engine utilized a Solex carburetor for fuel delivery, a common setup for European cars of this era. The XY6B engine produced a maximum power output of 72 horsepower (DIN) at 6000 rpm and a peak torque of 88 lb-ft at 3500 rpm. The engine block was constructed from cast iron, while the cylinder head was made of aluminum alloy. Lubrication was provided by a conventional wet sump system, with an engine oil capacity of 5 liters (5.28 US quarts / 4.4 UK quarts).
The 104 Coupe 1.4 was typically paired with a four-speed manual transmission, although a three-speed automatic transmission was also available as an option. The automatic transmission, while offering convenience, did noticeably impact the car’s acceleration and fuel economy. The transmission was a conventional torque converter type, offering smooth but not particularly rapid gear changes. The final drive ratio varied depending on the transmission chosen, with manual versions generally having a slightly longer ratio for improved fuel efficiency. The engine and transmission combination was front-mounted and drove the front wheels, a configuration typical for Peugeot vehicles of this period.
Driving Characteristics
The Peugeot 104 Coupe 1.4 offered a driving experience best described as nimble and economical. With 72 horsepower propelling a relatively lightweight body (around 1,847 lbs), acceleration was adequate for everyday driving, but not particularly brisk. The 0-60 mph time was estimated to be around 13-14 seconds. The car felt most at home in urban environments and on winding country roads, where its small size and responsive steering made it enjoyable to drive. The four-speed manual transmission allowed drivers to make the most of the engine’s powerband, while the optional automatic transmission provided a more relaxed driving experience, albeit at the expense of performance. Compared to the later 1.6-liter Coupe, the 1.4-liter version felt noticeably less powerful, particularly when fully loaded or climbing hills. However, the 1.4 offered better fuel economy, making it a more attractive option for drivers prioritizing efficiency.
Equipment & Trim Levels
The Peugeot 104 Coupe 1.4 was generally better equipped than the standard 104 saloon. Standard features typically included cloth upholstery, a basic instrument panel with speedometer, fuel gauge, and coolant temperature indicator, and front and rear seat belts. The Coupe also featured a more stylish interior trim, with a more sculpted dashboard and door panels. Optional extras included a sunroof, upgraded stereo system, tinted glass, and more luxurious upholstery options. The trim levels were relatively simple, with the 1.4 typically representing a mid-range offering. Later models saw the introduction of more comprehensive trim packages, offering features such as alloy wheels and upgraded interior trim. The steering wheel was typically a two-spoke design, and the seats offered reasonable comfort for short to medium-distance journeys.
Chassis & Braking
The Peugeot 104 Coupe 1.4 utilized a relatively simple chassis design. It featured independent front suspension with MacPherson struts and coil springs, providing a comfortable ride and good handling characteristics. The rear suspension employed a trailing arm setup with coil springs, which was less sophisticated but effective in providing a stable platform. The steering was a rack and pinion system, offering precise and responsive control. Braking was provided by disc brakes on the front wheels and drum brakes on the rear wheels. The braking system was hydraulically operated, offering adequate stopping power for the car’s weight and performance. Stabilizer bars were fitted to both the front and rear axles, helping to reduce body roll during cornering. The tires were typically 155/70 SR13, providing a good balance between grip and ride comfort.
Market Reception & Comparison
The Peugeot 104 Coupe 1.4 was generally well-received by automotive critics. It was praised for its stylish design, comfortable interior, and fuel efficiency. However, some critics noted that the 1.4-liter engine was somewhat underpowered, particularly when compared to larger coupes on the market. Compared to the 1.6-liter Coupe, the 1.4 offered a more economical option, but at the cost of performance. Fuel economy was a strong point, with the 1.4-liter version achieving around 35-40 mpg in typical driving conditions. Reliability was generally good, although the carburetor could require occasional adjustment. The 104 Coupe 1.4 competed with other small coupes of the era, such as the Renault 5 Gordini and the Fiat 128 Coupe, offering a similar blend of style, economy, and practicality.
