The Triumph TR4 is a classic sports car that was manufactured by the Triumph Motor Company between 1961 and 1965. Serving as the successor to the TR3A, the TR4 shares a similar chassis and drivetrain with its predecessor but features a modernized body design crafted by Michelotti. Notably, the TR4 was the first production car to offer an optional hardtop that included a fixed glass rear with an integrated rollbar, along with a detachable center panel. This innovative roof system predates the Porsche 911/ 912 Targa by five years. For versatility, the hardtop can be swapped out for a vinyl insert with a supporting frame, allowing for easy stowage of the latter, while the rigid panel is not designed to fit inside the vehicle, the vinyl insert and frame could be. The factory offered the rigid top and backlight assembly as the "Hard Top kit", and the vinyl insert and frame separately as the "Surrey top".
This specific example, built in March 1962 and in 'Fast Road' rally specification, boasts matching numbers and was meticulously restored for historic motorsport use in 2019/ 20 by Triumph specialist Classic Bodies Forell in Paderborn, Germany.
