was the Thrustmaster Formula T1, released in 1994. It had no force feedback, only some form of spring-based centering resistance proportional to the steering angle. Two of the earliest FFB wheels for the consumer PC market were the Microsoft Sidewinder Force Feedback Wheel, released in 1997, and the Logitech Wingman Formula Force.

Force feedback

Force feedback sim wheels have motors to simulate steering kickback. Racing wheels started off as simple plastic wheels hooked up to a rotary potentiometer, which were sprung by springs or bungees. These spring-based wheels had a reactive torque that increased proportionally only to the steering angle, without regard for the simulated vehicle dynamics.

' (pp. 180–188). Springer, Berlin, Heidelberg. Eventually manufacturers began to use electric motors in the controllers, in place of springs, in order to achieve a level of force feedback (sometimes abbreviated ), first seen in Microsoft's Sidewinder wheel. At first this technology simply provided the centering force and other artificial effects such as shaking the wheel in a crash or other vibrations. However, as driving simulations have evolved, their physics engines have become more elaborate, allowing also for linking the force feedback close to the simulated

of the in-game physics. This allows the user to truly feel what forces go through the steering rack, instead of just artificial effects, and genuinely enhance the realism of the game. A fundamental factor for an adequate subjective steering-feel and perception of drivability from a force feedback wheel, is the transfer function from steering torque to steering angle. In 2015, a preliminary comparison of gear-driven and direct-drive wheels in the 0–30 Hz frequency range, for a study on hard real-time multibody simulation and high-fidelity steering wheel force feedback, concluded that direct-drive wheels are preferable.Pastorino, R., Desloovere, M., Vanneste, F., Degezelle, P., Desmet, W., & Optidrive, N.
