1987 had arrived and development of the Thunderbird SuperCoupe, a successor to our TurboCoupes, was not complete. Ford decided to insert the 1987-1988 redesigned Thunderbird TurboCoupe into their lineup as a spacer, to allow for finished production of the SuperCoupe for model year 1989. This new Thunderbird combined a new front valence and rear-end with a few more tricks under hood to produce the ultimate stock TurboCoupe. The addition of intercooling significantly increased power output. The addition of rear disc brakes increased braking ability. Hood vents and a sloped front end gave this Thunderbird a bird-like appearance, in addition to plenty of power to play.
