Continuing in production until 1969, this version came in saloon and, from 1965, estate forms. The estate, its body shell partly built by Carbodies, was in the Mk 1 version the same length as the saloon. Various minor improvements were made during the period of which the most noteworthy, probably, was a significant upgrade in October 1966 to the "previously rather ineffective" ventilation, with eyeball vents added in the centre of the facia and the heater controls repositioned beneath them.[9]
In 1968 the 2.5 PI (petrol injection) Mk 1 was launched, fitted with a Lucas Automotive mechanical fuel injection system. Performance was very good, but the PI models (along with the TR6 models) gained a reputation for unreliability and poor fuel economy.
In Australia these models suffered badly because of the summer heat. The electric fuel pump commonly overheated causing fuel to vaporise and render the engine inoperable until the pump cooled down. The overheating of the pump was caused by a combination of very high pressure fuel loads (over 110 psi (7.6 bar)) and a pump that was adapted from what was originally a windscreen wiper motor. As such, it did not cope well with sustained pressures in moderate to high ambient temperatures. Because of the launch late in the Mk I's life, there are relatively few PIs in the original shape.
