4-door 4-seater saloon.

Final version of successful P6 model, with enlarged overhead-cam engine - 98/115bhp (single and twin-carb types) against 89/110bhp of superseded cars, but only tiny visual changes. Strengthened transmission to deal with extra torque, plus the larger (15-gallon) fuel tank once unique to the 3500 model. After this car, the overhead-cam engine was discontinued.
