About the Vehicle
The 1987 Ford EXP was a small, fuel-efficient car that served as the successor to the Ford Pinto, sharing a platform but offering a more refined driving experience. Built on the Ford Escort platform, the EXP was a unique model that blended the practicality of a compact economy car with a touch of sportiness and distinct styling. It was available in both sedan and hatchback configurations, with the 1.9L 4-cylinder engine being a primary powertrain option. This engine, known for its reliability and economy, was designed to maximize fuel efficiency, a key selling point during the late 1980s when fuel prices were a major concern for consumers. The 1.9L engine produced modest horsepower, prioritizing torque and smoothness over high-speed performance, making it ideal for city commuting and family errands.
Owners of the 1987 Ford EXP often appreciate the vehicle’s simplicity and durability.
