390-horsepower 3.9L Supercharged V8
With 390 horsepower on tap, the Ford Thunderbird 3.9-liter supercharged V-8 engine transforms the vehicle's character from a grand touring car into a performance-minded sports roadster. The supercharger setup offers peak horsepower at 6,000 rpm and 390 foot pounds of peak torque at 3,500 rpm, giving the Thunderbird concept car impressive power and acceleration capabilities.
Ford's powertrain engineers began the supercharged concept's transformation with a stock 3.9-liter DOHC modular V-8 engine from the standard Thunderbird. Then, all-new aluminum headers were fitted along with a Roots type supercharger to provide the necessary thrust.
