Introduction: In 1966, Volvo left the old design lines from the Amazon and moved to a different level that was kept until the '90s: the box design. At the same time, it introduced the new designation names with three numbers: first was the series of the vehicle, the second number was the number of cylinders and the last was the number of doors. In 1967, Volvo launched the two-door version for the 1st series, with four cylinders engines. So, the name was 142.
