Here's a breakdown:
* 1958-1969: "Speed-Stat" was offered. This system used an electric motor to maintain a set speed but required the driver to hold down a button to maintain that speed. This was a far cry from the automatic systems we are used to.
* 1971: The first true cruise control system, as we know it, was introduced on Chevrolet cars. This system allowed for the automatic maintenance of a set speed without the need for driver intervention.
Note: The first car with cruise control was the 1958 Chrysler Imperial.
Hopefully, this clarifies the timeline for cruise control in Chevy cars!
