The Daimler Conquest is an automobile which was produced by The Daimler Company Limited in the United Kingdom from 1953 to 1958. Based on the Lanchester Fourteen, the Conquest replaced the Daimler Consort. Sales were affected by increasing prices and by the fuel shortage caused by the Suez Crisis, and production ended by 1958.

Engine[edit]

The standard 1953 Conquest used a straight-six engine developed from the inline-four engine used in Lanchester's Fourteen and Leda models. The engine was made from cast iron and had a single Zenith carburettor and a compression ratio of 6.6:1. With a bore of 76.2 mm (3.00 in) and a stroke of 88.9 mm (3.50 in), the engine displaced 2,433 cc (2.433 L; 148.5 cu in) and delivered 75 bhp (56 kW).

The 1954 Conquest Century model had an alloy head with larger valves, higher compression, high lift cams, and twin SU carburettors.[2] These modifications raised the power to 100 bhp (75 kW) at 4400 rpm.[3][4]

Body, chassis, and running gear[edit]

Origins[edit]

The body was a slightly modified version of that used on the earlier Lanchester Fourteen.[5] Apart from the grille, The Conquest was identical in appearance to the Lanchester Leda. While the Fourteen had been coachbuilt of steel on a timber frame, the Leda had an all-steel body, on which the Conquest's was based. Lanchester was a subsidiary of Daimler.[2][6] The whole car appeared to have been developed within four months of Bernard Docker, then managing director of BSA, taking on the additional responsibility of managing director of Daimler in January 1953.

Presented as a new car, the 75 hp (1953–1956) Daimler Conquest saloon chassis and running gear had originated in the 1950 Lanchester Fourteen or Leda.[6][7]

The usual Daimler large cruciform chassis had a double wishbone front suspension, with laminated torsion bars, telescopic dampers, and an anti-roll bar, while the rear suspension used leaf springs with telescopic dampers.

The Conquest featured automatic chassis lubrication to 21 points, using a pump controlled by exhaust heat.

Cam and peg steering was used, and Girling hydro-mechanical brakes. (Hydro - mechanical = hydraulic front, mechanical rear brakes.) The cars had an 2,642 mm (104 in) wheelbase.[2]

In January 1955 it was announced that all new Conquests had four inches more leg-space for rear-seat passengers. In addition doors now opened wider and there were "further interior embellishments".[8]

Body styles[edit]

Conquest was offered in the following models:[note 1]

Performance[edit]

The Conquest's engine produced 75 hp (56 kW) at 4000 rpm, and 124 lb·ft (168 N·m) of torque at 2000 rpm. In Century form the dry liner, pushrod engine with its balanced crank and large water jacket, delivered 100 hp (75 kW) at 4000 rpm, and 130 lb·ft (176 N·m) of torque at 2400 rpm. A Daimler four-speed preselector gearbox with "fluid flywheel" was used.

The Saloon had steel bodies weighing 1,397 kg (3,080 lb) (Conquest: 81 mph (130 km/h), 0-60 mph: 20.4 seconds. Conquest Century: 90 mph (140 km/h)).

The open two-seater Roadster (3) had an aluminium body, except for the bonnet, and aluminium castings were used instead of a traditional timber frame. The Roadster used (pioneered) the Century form of the Conquest engine though when it was first announced in the Roadster it was said to produce just 90 bhp. (100 mph, 0-60 mph: 14.5 seconds, 25.5 cwt (1300 kg))

The 4-seater drophead coupé (2) had a powered roof folding mechanism and shared few body parts with the Roadster. (87 mph (140 km/h)), 0-60 mph: 16.3 seconds)

The New Drophead (3) had steel to the B-pillars, and alloy from there back, apart from steel inner rear guards. (89 mph (143 km/h)), 0-60 mph: 19.7 seconds)

The lighter Roadster (3) was slightly taller geared; while the heavier New Drophead also (3) was slightly lower geared. Other differences to the Conquest saloon (1) include 12-inch-wider (13 mm) brakes, and steering that was 2½ turns lock-to-lock instead of 3¼.[2]

A saloon tested by The Motor magazine in 1953 had a top speed of 81.6 mph (131.3 km/h) and could accelerate from 0-60 mph (97 km/h) in 24.3 seconds. A fuel consumption of 20.3 miles per imperial gallon (13.9 L/100 km; 16.9 mpg‑US) was recorded. The test car cost £1511 including taxes.[1]

Production history[edit]

The Conquest saloon was released to the public in 1953 as a replacement for the Daimler Consort, but was shorter and lighter, with better performance. The Daimler Conquest was meant to be an affordable Daimler, priced at 1066 pounds. (That price may well be linked to the name "Conquest".) It was pedigree with pace, at a reasonable price. They still had luxurious, well-appointed traditional wood-grain and leather interiors. Actual construction was by another BSA subsidiary, 'Carbodies'.

The open 2-seater Conquest Roadster was first shown to the public[10] at the Motor Show in 1953 with the tuned engine later known as the Century engine. The Roadster was not available to the public till 1954.

The Daimler Conquest Century, released in 1954[3] was the best seller of the range with 4818 of them produced. A hundred-horsepower and, presumably downhill, a hundred miles an hour, hence the Century.

The Conquest Roadster was dropped from production in 1955. The dropheads had outsold them by over 3:1. Then a new drophead 4-seater and a drophead coupé version of the 2-seater Roadster were introduced at the 1955 Motor Show. This Mark II Conquest Roadster drophead coupé had a sideways-facing single rear seat, making the car a 2- or 3-seater and with wind-up side windows in place of the clip-on side-curtains of the continuing Mark II open 2-seater Conquest Roadster.

Two of the roadsters, at least, were coach-built as fixed head coupés.[11] [ However at this time many very small businesses indeed offered low-cost glass-fibre-reinforced removable tops for all brands of open sports-cars. ] There is one fibreglass new drophead, and one fibreglass fixed head coupé (with a Hillman Minx Californian three piece rear window!!) One-offs seem to have been mostly done on Roadster allocated chassis, so there may have been even fewer roadsters built than officially indicated.

In October 1956[12] Daimler Conquest Century buyers were offered the choice of an automatic transmission or the traditional preselector system. Time was changing gear. Preselector gearboxes faded away as modern automatic transmissions took their place. Currency restrictions had meant that until Borg-Warner built a British plant automatic transmissions were only available on export cars.

Pricing[edit]

The price of the Conquest was reduced in April 1956 by 12%[13] and again in September 1956 by between 7% and 16%.[14]

The Suez Crisis in the summer of 1956 had brought Europe petrol rationing which began France on 29 November and two weeks later in Britain. In Britain the restriction lasted until mid May 1957 bringing, amongst other economic dislocation, short time working to the British motor industry.[note 2]

The Roadster had started out priced close to the Jaguar XK120 at £1673, but by the time the New Drophead was released the price was £280 more than an XK140. While Jaguars became less expensive, the hand built Daimlers escalated in price. Jaguars sold in large numbers, and Daimlers sold in small numbers with frequent model changes.[citation needed]

Daimler's problems became increasingly obvious.[2] In 1960 Daimler was bought by Jaguar, who wanted the additional factory space . Four years after the Conquest ceased production, Daimler introduced the Daimler 250 to the same market sector. The 250, using Daimler's 2548 cc V8 in the Jaguar Mark 2 body shell, proved to be the best selling Daimler motor car ever, with more than 17,000 sold between 1962 and 1969.[15]

Production figures[edit]

  • 4568 Daimler Conquest Saloons (1)
  • 4818 Conquest Century Saloons (1)
  • 65 Conquest Roadsters, (3)
  • 234 Conquest Century Drophead Coupés, (2)
  • 54 Conquest Century New Drophead Coupés (3) (A.K.A. the Mark II)[2]

In August 1956 a press release[16] endeavoured to relieve the workforce's belief that all production was to stop. In the chairman's speech to the November 1958 shareholders' AGM he advised the only cars made in the year ended 31 July 1958 were the 3½ and 4½ litre models

    A variation of the Conquest model providing more power and speed with increased passenger room and equipment, is being produced by the Daimler Company. Its name, the Conquest Century, is derived from the increase in power of the 2½ litre six-cylinder engine from the 75 bhp at 4,000rpm of the standard Conquest saloon to 100bhp at 4,400 rpm, the increase in power being obtained by fitting dual carburettors, a special aluminium cylinder head, a different camshaft, large valves and a twin exhaust manifold. The basic price of the Conquest Century saloon is £1,172 compared with £1,066 for the standard Conquest saloon. The price of a new model with purchase tax is £1,661 9s. 2d.

    Lanchester Fourteen. Features Of New Model From our motoring correspondent.
    Coventry October 10. One of the new cars to be shown at the Motor Exhibition was displayed privately to the Press here today by the Lanchester Motor Company Limited a member of the Daimler Group.
    The car is the Lanchester Fourteen, a completely new model, the only familiar feature being the famous Daimler fluid transmission with pre-selective gearbox. The car has a two-litre, four-cylinder engine and a handsome four-five-seater saloon body which will be made at first by coachbuilding methods. Next year when the rebuilding of 300,000 square feet (28,000 m2) of factory space destroyed in the Coventry raids is completed, it will have a pressed steel body which will reduce the weight, enable the price of £895, plus purchase tax, to be considerably reduced and permit shipment in a form suitable for assembly overseas.
    The new Lanchester Fourteen has features of technical interest. The torsion "bars" of the independent front suspension consist of laminated leaves, instead of the usual bars while the chassis (except the propeller shaft and water pump) is automatically lubricated every time the engine is started and warmed up.
    (It may have been as much as another twelve months before deliveries began. In December 1952 only "a limited number" had been released on the home market.)

    New Daimler Car. "Conquest" Saloon Model
    A new Daimler car–the Conquest– is announced today. The company states that it has greater pace and far better acceleration than any of its predecessors. It is a full five-seater saloon model, powered by a new six-cylinder 2½ litre short stroke engine which develops 75 bhp at 4,000 revolutions a minute.
    The car has shown itself capable of accelerating from stop to 30 mph (48 km/h) in 5 seconds and of reaching 70 mph (110 km/h) through all gears in 30 seconds. It has a top speed of just under 82 mph (132 km/h). Petrol consumption ranges from 26.6 mpg at a constant 30 mph (48 km/h) to 18.5 mpg at a steady 70 mph (110 km/h); the average consumption is 20.3 mpg. Hill-climbing tests have shown the Conquest capable of a maximum top-gear speed of 67 mph (108 km/h) up a gradient of 1 in 20. It can climb a 1 in 10 hill at 43 mph (69 km/h).
    Interior heating and air-conditioning are included as standard equipment. [turning the heater temperature to cold allows its fan to draw in unheated air from outside the cabin] The basic cost of the Conquest is £1,066; with purchase tax the price is increased to £1,511 5s 10d.
