Key Highlights of the Abarth 131 Rally

1. Development and Purpose

2. Engine and Performance

• Engine: The Abarth 131 Rally was equipped with a 2.0-liter inline-four engine, heavily modified from the original Fiat 131’s engine.
• Power Output: This engine produced around 215 horsepower in rally trim, which was impressive for the era, especially for a car based on a family sedan.

• Performance: Despite its modest size, the 131 Abarth Rally could accelerate rapidly and was incredibly agile, which was a huge advantage on challenging rally stages.

3. Chassis and Handling

• The car featured a lightweight body with extensive use of fiberglass and aluminum to reduce weight, bringing it down to around 930 kg (2,050 lbs).
