Turn the steering wheel far enough, and the 1988 Honda Prelude 4WS would reverse its rear steering direction—all through a mechanical shaft and gearbox.
This third-generation Prelude used steering angle to control the rear wheels. Small inputs steered them with the fronts; larger inputs eventually steered them the opposite way. There was no road-speed sensor deciding between highway stability and parking-lot agility. Honda built that compromise directly into the mechanism.
The tighter turning circle was useful. Car and Driver’s comparison of two-wheel-steering and four-wheel-steering Prelude Si models also found an advantage in dry lane changes. Wet-weather results were less flattering, and skidpad testing showed why rear-wheel steering should not be mistaken for extra tire grip.
The Prelude’s pop-up headlights and double-wishbone suspension set the scene for a distinctly 1980s Japanese engineering gamble. A second steering system added cost and service complexity, and Honda’s owner’s manual warned about unexpected rear-end swing near obstacles. Comparing mechanical 4WS with later electronic rear steering shows how engineers addressed its limitations.
It’s the sort of engineering you could demonstrate to a friend before either of you ever left the parking lot.
