⚙️ Engine Specifications

Engine Family:

Fiat FIRE (Fully Integrated Robotized Engine) and other Fiat OHC variants of the period.

Engine Displacement Options:

Common displacements for 1984 models included 903cc, 1116cc, and 1299cc (often referred to as 1.3).

Typical Horsepower Range:

34-70 hp (depending on engine size and tuning, e.g., 903cc ~34-45 hp, 1116cc ~45-55 hp, 1.3 ~60-70 hp for hotter variants).

Primarily carburetor-fed (e.g., Weber, Solex) for base models. Some higher performance or later models may have featured early electronic fuel injection (EFI).

Ignition Type:

Conventional contact breaker points ignition or early electronic ignition systems.

Layout:

Transverse, front-wheel drive

🔧 Transmission

Transmission Type Standard:

4-speed manual transmission. A 5-speed manual was also available on many models.

Transmission Type Optional:

3-speed automatic transmission was an option on some variants.

Clutch Type:

Dry single-plate clutch, hydraulically or cable operated.

📐 Dimensions

Body Styles:

Primarily a 3-door hatchback. A 5-door version was introduced later in the model's life cycle but less common for the 1984 model year.

Curb Weight Range:

Approximately 750-900 kg, depending on engine and equipment.

🛡️ Safety Features

Crash Test Era Context:

Safety standards of the mid-1980s were less stringent than today. The Uno generally performed adequately for its class and time but lacked advanced safety features.

Braking System:

Front disc brakes, rear drum brakes. ABS was not standard or widely available on this model.

Restraints:

Seat belts (lap and diagonal in the front, lap belts in the rear). Airbags were not available on the 1984 model.

💡 Technology Features

Audio System:

Basic AM/FM radio, potentially with cassette player, as an optional extra. Standard models often had no audio system fitted.

Assistance Features:

None beyond standard braking and steering systems. No driver assistance electronics.

🔧 Maintenance

Oil Change Interval:

Typically 7,500 - 10,000 km (4,500 - 6,000 miles) or 6-12 months, depending on usage and oil type used.

Timing Belt Replacement:

Crucial for FIRE engines. Intervals typically range from 50,000 to 70,000 km (30,000 - 45,000 miles) or 4-5 years. Non-replacement can lead to catastrophic engine failure.

Spark Plug Replacement:

Approximately 20,000 - 30,000 km (12,000 - 18,000 miles) or 2 years. Specific plug type and gap are critical.
