The T60/4 was produced from October 1960 and are mechanically and outwardly similar to the late T60. It was the same length and width as the standard T60, but differed in having extra room in the back for two seats, the additional space being created by a revised rear body moulding, thus creating proper seats in the back for two children. The rear bench seat was fastened to the car and the centre backrest had a bulge in it because of the revised rear wheel arch. The Car was available in both soft-top and hardtop forms. These cars used the revised front and rear suspension layouts used on the very late T60s.
