4. Ford Taurus SHO (Yamaha V6)
The 1989-1995 Ford Taurus SHO was a wolf in sheep’s clothing. This otherwise ordinary sedan hid a high-revving, Yamaha-designed V6 engine under its hood, giving it far more power than its appearance suggested. Muscle car enthusiasts were routinely stunned as the SHO surged ahead at stoplights, easily outpacing expectations. As Hagerty notes, the SHO helped redefine what a sleeper could be.
