Rover P4 Features, Photos and Videos

October 30, 2018 Posted By Daniel Johnson

The Rover P4 series is a group of mid-size luxury saloon cars produced by the Rover Company from 1949 until 1964. They were designed by Gordon Bashford.

Their P4 designation is factory terminology for this group of cars and was not in day-to-day use by ordinary owners who would have used the appropriate consumer designations for their models such as Rover 90 or Rover 100.

Production began in 1949 with the 6-cylinder 2.1-litre Rover 75. Four years later a 2-litre 4-cylinder Rover 60 was brought to the market to fit below the 75 and a 2.6-litre 6-cylinder Rover 90 to top the three-car range. Several variations followed.

These cars are very much part of British culture and became known as the 'Auntie' Rovers. They were driven by royalty including Grace Kelly.

The P4 series was supplemented in September 1958 by a new conservatively shaped Rover 3-litre P5 but the P4 series stayed in production until 1964 and their replacement by the Rover 2000.

The earlier cars used a Rover engine from the 1948 Rover 75. A four-speed manual transmission was used with a column-mounted gear change at first and floor-mounted unit from September 1953. At first the gearbox only had synchromesh on third and top but it was added to second gear as well in 1953. A freewheel clutch, a traditional Rover feature, was fitted to cars without overdrive until mid-1959, when it was removed from the specifications, shortly before the London Motor Show in October that year.

The cars had a separate chassis with independent suspension by coil springs at the front and a live axle with half-elliptical leaf springs at the rear. The brakes on early cars were operated by a hybrid hydro-mechanical system but became fully hydraulic in 1950. Girling disc brakes replaced drums at the front from October 1959.

The complete body shells were made by the Pressed Steel company and featured aluminium/magnesium alloy (Birmabright) doors, boot lid and bonnets until the final 95/110 models, which were all steel to reduce costs. The P4 series was one of the last UK cars to incorporate rear-hinged "suicide" doors.

Announced by Managing Director Spencer Wilks on 23 September 1949 the new Rover 75, now the only Rover in production, was first displayed at the opening day of the Earls Court Motor Show on 28 September 1949. It featured unusual modern styling in stark contrast with the outdated Rover 75 (P3) it replaced. Gone were the traditional radiator, separate headlamps and external running boards. In their place were a chromium grille, recessed headlamps and a streamlined body the whole width of the chassis. A steering column-mounted gear lever was fitted.

The car's styling was derived from the then controversial 1947 Studebakers. The Rover executives purchased two such vehicles and fitted the body from one of them to a prototype P4 chassis to create a development mule. James Taylor's book 'Rover P4 – The Complete Story' says that this vehicle was affectionately known as the 'Roverbaker' hybrid.

Malcolm Bobbit states "The P4 set the seal on the future with a vengeance. Rover defied its critics with the P4's new look and to get some idea of the shock of the new, consider some of its rivals . . . astonishment at the P4's courageous styling." The P3 had almost no boot at all yet that had been considered rather more than adequate. The new car's bonnet-like extension to its rear was ridiculed; the driver sat well forward looking out over a relatively short bonnet and the rear wheels were set well back behind the back seat. All the new car's proportions were different from all the other new cars.

Another, at the time minor, distinctive feature but this one did not catch on was the centrally mounted light in the grille where most other manufacturers of good quality cars provided a pair, one fog and one driving light often separately mounted behind the bumper. Known as the "Cyclops eye" it was discontinued in the new grille announced 23 October 1952.

Power came from a more powerful version of the previous model's 2.1 L (2103 cc/128 in³) Rover IOE straight-6 engine now with chromium-plated cylinder bores, an aluminium cylinder head with built-in induction manifold and a pair of horizontal instead of downdraught carburetters. A four-speed manual transmission was used with a column-mounted gear lever which was replaced by a floor-mounted mechanism in September 1953.

A car tested by The Motor magazine in 1949 had a top speed of 83.5 mph (134.4 km/h) and could accelerate from 0–60 mph (97 km/h) in 21.6 seconds. A fuel consumption of 27.8 miles per imperial gallon (10.2 L/100 km; 23.1 mpg‑US) was recorded. The test car cost £1106 including taxes. The turning circle was 37 feet (11 m).

". . . and I honestly believe (barring the Rolls-Royce) that there is no finer car built in the world today." Bob Dearborn, Tester Road and Track. Road test no. F-4-52, August 1952.

After four years of the one model policy Rover returned to a range of the one car but three different sized engines. In September 1953 it announced it would supply a four-cylinder Rover 60 and a 2.6-litre Rover 90 adding them to the 75's 2.1-litre six. Rover's stated intention was "to cater for a wider field of motorists who require a quality car with varying degrees of economical running costs and performance".

On the same day there were modifications announced which were accordingly shared by all three:

Rover also announced an all-round reduction in Rover and Land-Rover prices. This was a response to a slump in both home and export sales of all British cars.The 2.103 litres (128.3 cu in) IOE engine continued.
