Welcome to today’s episode, where we dive into the intriguing world of four-wheel steering, or 4WS. This concept, while not new, has had a complicated history in the automotive industry. Early versions appeared in American 4x4 trucks over a century ago, but it gained prominence in the 1980s with models like the Honda Prelude Si. As the article notes, “The idea of steering a two-axle vehicle's front and rear wheels isn't new,” yet it faced challenges with execution and marketing.

The mechanics of 4WS are fascinating. At low speeds, the rear wheels turn in the opposite direction of the front wheels, enhancing maneuverability. This means tighter turns in cramped spaces. At higher speeds, the rear wheels mimic the front's direction slightly, improving stability during lane changes and high-speed cornering.

Honda's early system was entirely mechanical, making waves for its impressive steering feel. Critics like L.J.K. Setright praised it as "the finest steering in the history." Conversely, Nissan introduced its HICAS system, which was sensor-driven and only engaged at higher speeds.

While 4WS had potential, various factors—including rising costs and complex engineering—kept it from becoming mainstream. However, the essence of four-wheel steering remains relevant today, offering improved handling and maneuverability. So, whether in a sporty coupe or a modern pickup, 4WS continues to iterate, proving that good ideas are worth revisiting.
