Cars 3 is a computer animated prototype.
== Mass production ==Large-scale, production-line manufacturing of affordable cars was started by Ransom Olds in 1901 at his Oldsmobile factory in Lansing, Michigan and based upon stationary assembly line techniques pioneered by Marc Isambard Brunel at the Portsmouth Block Mills, England, in 1802
The development of external combustion engines is detailed as part of the history of the car but often treated separately from the development of true cars
