As we wait for the upcoming hybrid variant, the iconic Mustang continues to offer a turbocharged 2.3-litre four-cylinder engine producing 310 horsepower in EcoBoost trim and the legendary 5.0-litre V8 rated at 460 horsepower in GT trim (480 in the Bullitt Edition). The 2020 model year brings many technical upgrades to the 526-horsepower Shelby GT350R. More importantly, it marks the return of the super-fast Shelby GT500 with a supercharged V8 unleashing 760 horsepower… but no manual gearbox.
