The Tesla Model S was the first Tesla model to use the company’s Autopilot driver-assistance hardware.
Tesla introduced Autopilot hardware on Model S vehicles in 2014. The initial system used forward-facing cameras, radar, and ultrasonic sensors to support features such as adaptive cruise control and lane-centering assistance when available and properly supervised.
Autopilot is a driver-assistance system, not a fully autonomous driving system. Tesla’s own instructions require drivers to remain attentive, keep their hands available, and be prepared to take control. The name has therefore generated continuing discussion about the difference between assisted driving and autonomous operation.
Later Tesla models, including Model X and Model 3, received related hardware and software systems. The original Roadster predates Autopilot and did not launch with these driver-assistance capabilities.
