⚙️ Engine Specifications

Engine Options 1992:

Typically included 1.0L (FIRE), 1.1L, 1.3L, and 1.4L petrol engines. Some markets may have had diesel variants (e.g., 1.3L Diesel). Specific engine details (e.g., FIat's FIRE engine) are crucial for precise repair.

Power Output Range:

Varies by engine displacement, generally ranging from approximately 45 hp to 70 hp for petrol engines.

Torque Output Range:

Correlates with power output, typically in the range of 70 Nm to 100 Nm.

Fuel Delivery Type:

Carburetor (e.g., Weber, Solex) for most 1992 models, with potential for early fuel injection systems on some higher-spec variants.

Fuel Type:

Unleaded Petrol (Gasoline)

🔧 Transmission

Transmission Type Standard:

5-speed manual transmission

Transmission Type Optional:

3-speed automatic transmission (less common, but available on some variants)

Clutch Type:

Hydraulically operated single dry plate clutch

📐 Dimensions

Body Styles:

3-door hatchback, 5-door hatchback

Curb Weight Range:

Approximately 800 - 950 kg, depending on engine and body style.

🛡️ Safety Features

Crash Test Ratings:

Euro NCAP or equivalent testing for this era was less standardized. The Uno was known for its compact design and modest safety features for its time.

Active Safety:

Standard brakes, basic anti-roll bars, direct steering (no power assist on base models).

Passive Safety:

Seat belts, reinforced passenger cell (typical for the era). Airbags and ABS were generally not standard on 1992 models.

💡 Technology Features

Infotainment Features 1992:

Basic AM/FM radio with cassette player was common. Some higher trims might have featured more speakers.

Driver Assistance Features:

Limited to standard braking and steering systems. ABS and airbags were generally optional or not available.

Connectivity Features:

No modern connectivity features (e.g., Bluetooth, USB) were available.

🔧 Maintenance

Oil Change Interval:

Typically 5,000 - 7,500 miles (8,000 - 12,000 km) or 6-12 months, depending on driving conditions.

Timing Belt Replacement:

Crucial for FIRE engines; typically every 30,000 - 50,000 miles (50,000 - 80,000 km) or 4-5 years. Failure can cause catastrophic engine damage.

Engine Oil Specification:

SAE 10W-40 or 15W-40 API SG or higher (check specific engine variant and manual for precise details).

Coolant Specification:

Ethylene glycol-based coolant, typically a 50/50 mix with distilled water. Mopar OAT coolant or equivalent often recommended.

Brake Fluid Specification:

DOT 3 or DOT 4 brake fluid.

Transmission Fluid Manual:

API GL-4 SAE 75W-90 or 80W-90 gear oil (check manual for specific type and capacity).

Common Issues Engine:

Carburetor wear/adjustment issues, ignition system component failures (coil, distributor), timing belt failure (if not replaced on schedule), oil leaks.

Common Issues Electrical:

Corrosion in wiring harnesses, failure of switches, alternator issues, aging fuses and relays.

Common Issues Body:

Rust and corrosion, particularly on sills, wheel arches, and floor pans, due to the age of the vehicle and materials used.

Common Issues Suspension:

Worn bushings, worn ball joints, leaking shock absorbers, play in steering rack.

📚 Vehicle History

Fiat Heritage:

Fiat has a long history of producing small, economical, and innovative city cars. The Uno continued this tradition, succeeding models like the Fiat 127.

Uno Evolution To 1992:

Launched in 1983, the Uno was a significant departure for Fiat, featuring a modern, boxy design with aerodynamic considerations. By 1992, it had received several facelifts and updates, including revised engines, interior refinements, and improved safety features over its initial run.

Manufacturing Locations:

Primarily Italy, but also produced under license in various countries, including Poland (as the Fiat 126p), Brazil, and South Africa.

🏆 Awards & Recognition

Automotive Journalism Awards:

The Fiat Uno was critically acclaimed upon its launch and was named 'European Car of the Year' in 1984. It was praised for its innovative design, practicality, and fuel efficiency.
