When it appeared in 1965, there were two Cessna 206s. One was designed to carry passengers, the other was used as a utility vehicle. The two would finally merge a few years later and give birth to the Cessna Stationair.
The production of the 206 stopped in 1985 as did all single-engine Cessna planes. Production resumed in 1994 and this was the time to market a turbocharged engine version: the Cessna 206 Turbo, and two versions powered by Rolls-Royce Motors.
