Mark II The Mark II version of the P5 was introduced in 1962. It featured more power, , from the same 3-litre engine and an improved suspension, while dropping the glass wind deflectors from the top of the window openings which also, on the front doors, now featured "quarterlight" windows. The most notable addition to the range was the option of the Coupé body style launched in autumn 1962. Unlike most coupés, which tend to be two-door versions of four-door saloons, this retained the four doors and was of the same width and length as the saloon, but featured a roofline lowered by along with thinner b-pillars, giving it the look of a hardtop. Hydrosteer power-assisted steering was standard on the coupé and optional on the saloon. Production of the Mark II ended in 1965, by which time 5,482 coupés and 15,676 saloons had been produced.

While this added some weight, it still maintained the engine's light and compact features. The Borg Warner Type-35 automatic transmission, hydrosteer variable ratio power steering and front Lucas fog lights were now standard. Output of
