The Daimler DK400, originally Daimler Regina DF400, was a large luxury car made by The Daimler Company Limited between 1954 and 1959 replacing their Straight-Eight cars. Distinguished, after the Regina, by its hooded headlights it was Daimler's last car to use their fluid flywheel transmission.

The Regina, DF400 and DK400 chassis was generally equipped with steel limousine bodywork by Carbodies (identified as DK400B) with a drop division, three occasional seats and more luxurious trim in the rear compartment than in the DK400A owner-driver car.

The Regina limousine was shown at the Earls Court Show in October 1954 and then described as being built on a special edition of the Regency chassis. [6] Some chassis were bodied as hearses and at least one was equipped with a coupé body for Lady Docker.

An unusual feature of the limousine was that the occasional middle seats were three abreast. [7]

Final big straight-six engine, move to a new price class

The DK400 was the last of the larger of the old long-stroke straight six engines that had been traditional on Daimler's smaller cars since 1910 though production of the smaller 3.8-litre engine, modified to take Borg-Warner's automatic transmission, continued until 1962.

When introduced in 1954 the engine's output was 127 horsepower (95 kW) at 3,600 rpm. [2] In the autumn of 1955 the outputs of both the 3½-litre and 4½-litre engines were substantially increased, the 4½-litre to 167 horsepower (125 kW) at 3,000 rpm. [8] The standard wheelbase versions were re-designated DF402. The long wheelbase limousine remained designated DK400 but its name, Regina, was dropped as was the price of the complete standard-bodied limousine, by more than one-third. Modifications to the limousine's engine led to a similar output of 167 hp but at 3,800 rpm. [9]

Final fluid flywheel transmission

The DK400 was the last new Daimler model to use the company's preselector gearbox with fluid flywheel transmission introduced in 1930. A major change in gearing, however, saw the direct-drive top gear replaced by a direct-drive third and an overdrive top. [2] This, intended to improve the car's ability to cruise at high speed with its large engine, could lead to failure because the transmission could not always cope with the torque available from an engine capable of producing 167 horsepower (125 kW) at 3,000 rpm. [5]

It was replaced in the Majestic by a more modern Borg-Warner fully automatic transmission which required modification of the engine and crankcase castings. [3]

Royalty

The DK400 was as much as 500 kilograms (1,100 lb) lighter than previous postwar Daimlers.[ citation needed ] Two with Hooper bodies, the limousine in royal livery, were supplied as Royal Stock in 1955 and 1956, the limousine was repainted black and sold in 1958 but the landaulette was used by the Queen Mother.

A 4-door all-weather tourer by Hooper, body 10236 on chassis 92724, was specially designed and constructed for Mohammed Zahir Shah, King of Afghanistan. [11]

By the mid 1990s with the country in political turmoil, the same vehicle, part of the national museum collection, was used as target practice by soldiers and was in a dilapidated state with other vehicles before being taken away and scrapped.

It was the first Daimler car to be based on a Jaguar platform, the first with a unit body, and the last to feature a Daimler engine after the company was bought from the Birmingham Small Arms Company by Jaguar Cars in 1960. The engine is the hemispherical head V8 designed by Edward Turner and first used in the Daimler SP250 sports car.

Daimler V-8 engines were designed for the Daimler Company by Edward Turner and produced from 1959 to 1969. Initially used in the SP250 sports car and the Majestic Major saloon, the engine was mostly used in the Daimler 2.5 V8 saloon made with Jaguar Mark 2 unit bodies from 1962 to 1969. Approximately 20,000 of the 2.5-litre version of the engine were made for use in the SP250 and the 250 saloon, while approximately 2,000 of the 4.5-litre version were made for use in the Majestic Major saloon and its limousine variant which remained in production until 1968.

Edward Turner had been appointed Chief Executive of BSA Automotive in 1957 and promised new products, this car was to carry his new V8 engine still under development. The six-cylinder, four-door saloon, with new three-speed Borg Warner automatic transmission, power steering and vacuum-servo assisted four-wheel disc brakes was mechanically up-to-date for its time, but it had a heavy coachbuilt body of outdated construction on a separate chassis which kept the car's mass well above more modern designs and made it difficult to manoeuvre, despite the modern steering. The styling was already becoming outdated when the car appeared and became increasingly dated as lighter cars with monocoque construction appeared during the Majestic's production run.

The King’s not quite finished new Daimler 22 was reported to be the chief attraction of the show.
