⚙️ Engine Specifications

Engine Variants:

The 1977-1981 Fiat 127 typically featured inline-four cylinder engines. Common displacements include 903cc, 1049cc, and 1301cc (for Abarth or performance variants). Specific engine codes (e.g., Fiat 100 series for smaller engines) would be detailed in the manual.

Typical Horsepower:

Ranging from approximately 45 hp (for 903cc) to around 70 hp (for 1301cc in Abarth versions). Actual figures vary by engine and market.

Torque Figures:

Torque figures would vary significantly with engine size, typically ranging from 70 Nm to over 90 Nm for the larger displacement engines.

Fuel Delivery:

Primarily carbureted. Common carburetor types would be Weber or Solex. The manual would detail specific models and their adjustments.

Engine Code Examples:

Examples might include 100.000 (903cc), 124.000 (1290cc), 149.000 (1301cc for Abarth). The manual will list specific codes for the years covered.

🔧 Transmission

Standard Transmission:

4-speed manual transaxle.

Optional Transmission:

Some markets and later models may have offered a 5-speed manual transaxle or a 3-speed automatic transaxle as an option, though less common.

Transmission Features:

Transaxle (integrated engine and transmission unit) with front-wheel drive. Manuals will cover clutch operation, adjustment, and transaxle fluid changes.

📐 Dimensions

Wheelbase:

Approximately 2,150 mm (84.6 inches).
