Tesla vehicles built between September 2014 and October 2016 were equipped with one camera used for Autopilot. But new Tesla cars now have eight cameras that provide 360-degree visibility and 250 meters (820 feet) of range.
New Tesla cars still come with one radar sensor, but it has enhanced processing that allows it to see through heavy rain, fog, dust, and even a car in front of it.
Tesla is also still using 12 ultrasonic sensors — however, they have been updated to detect hard and soft objects at nearly twice the distance of the previous sensors.
