Strengthening Ford’s performance reach for 2020 and just in time for the pony car’s 55th anniversary, the new 2.3L High Performance Package for the entry-level Mustang EcoBoost creates the most powerful four-cylinder sports car offered by an American automaker. This is the result of a unique EcoBoost engine powered by Ford Performance and upgraded handling components from the Mustang GT Performance Package.

Reminiscent of development of the original Mustang in 1964, the car began as a five-person skunkworks project in the Ford Performance garage. Following an experiment with a Focus RS engine swap, the Mustang team leveraged Ford’s quickening product development times to accelerate and complete the design-to-approval process for the 2.3L High Performance Package in under 10 months.

Available on the entry-level Mustang EcoBoost fastback coupe or convertible models this fall, the Mustang EcoBoost package was developed to feel at home both on thrilling mountain and coastal roads and even on the most precise autocross courses thanks to its Mustang GT brakes, performance tires, and chassis and aerodynamics hardware from the Mustang GT Performance Package.
