The Triumph TR4 is a fancy car made in Britain by the Triumph Motor Company between 1961 and 1965. During its development, the car called "Zest" was built using the chassis and drivetrain from the earlier TR sports cars. However, it had a new body design created by Michelotti. During the production years, a total of 40,253 cars were made. The TR4 was very popular and maintained the tough and powerful image of the previous TR models.
