The Peugeot 403 is a car produced by French automobile manufacturer Peugeot from 1955 to 1966.
The 403 made its debut in saloon body style on 20 April 1955 at the Trocadéro Palace in Paris. The engine size gave the car a "tax horsepower" of 8 CV (8 hp), which placed it a class below the soon-to-be-replaced 11 CV Citroën Traction, but at least one class above the small cars produced by the principal competitor manufacturers.
When it was first shown, and until after 1958, the leading edge of car's nose carried an angular, forward-leaning chrome lion bonnet ornament – the lion image being Peugeot's trade mark. That was removed for 1959, due to safety concerns, and the logo was incorporated into a shield-shaped grill emblem.
Subsequently the semaphore-style trafficators on the C-pillars were replaced with flashing indicators within the light cluster. The front lights were modified to conform to new standards and in 1957 parallel windscreen wipers were substituted for the original "cross hands" ones featured at launch.
Although the car was subject to various improvements during the production run, these were mostly very minor in nature. Improvements for 1959 included moving the nozzles for the windscreen washer from the strip of metal between the base of the windscreen and the bonnet/hood a short distance to the rear edge of the bonnet/hood itself, thus presumably improving the angles at which the washer water hit the screen. This was also the year that the semi-circular ring inside the lower half of the diameter of the steering wheel used to operate the horn was replaced by a full circular horn-ring, so that drivers accustomed to holding the upper half of the steering wheel did not need to loosen their grip in order to sound the the horn.
Styled by Pininfarina, the 403 featured ponton, three-box styling incorporating, except on the most basic models, an opening roof panel.
The 403 came with an enlarged version of the Peugeot 203's 1290 cc petrol engine. Displacing 1,468 cc, the straight-four unit employed pushrod-actuated valves and hemispherical combustion chambers and a crossflow cylinder head to produce 65 hp (48 kW) at about 5,000 rpm and 75 lb·ft (102 N·m) of torque at 2,500 rpm. An unusual feature at the time was the thermostatically controlled engine fan which cut out when the engine temperature fell to 75°C and reengaged when the engine temperature increased to 84°C. Claimed advantages included an improvement in fuel consumption of between 5% and 10% according to average speed and the avoidance, under many conditions, of fan noise. Another little noticed but ingenious feature involved a small hot water based heating device for the carburetor linked to the heater for the passenger cabin in such a manner that it operated only when the driver turned on the heater and not when the ambient temperature was high enough for the heater to be left off.
A diesel powered Peugeot 403 estate was introduced in the Autumn of 1958, the first of a long line, followed by a diesel saloon a year later.
Upon the 203's discontinuation in 1960, a 47 hp version of its 1,290 cc powerplant became available as an option on a reduced specification version of the 403, branded initially as the "403 Sept" ("7") and soon afterwards as the "403 Berline Luxe". Car tax in France was based on engine size, and the smaller engined 403 fell within the 7CV taxation class rather than the 8CV of the bigger version.
The 403 came with a manual 4-speed all-synchromesh transmission driving the rear wheels. The gear change lever stuck out from the right side of the steering column.
For the Paris Motor Show in October 1957 the manufacture offered, at extra cost, an electro-magnetic Jaeger automatic clutch, activated when changing gear.
An unusual feature on the inside of the 403 involved the front seats which reclined to the point where the seat backs were flush with the cushions of the rear seat, thus creating a "couchette", sometimes described in English language sources, optimistically, as a double bed.
The wheelbase was lengthened by 24 cm (10 inches) for the five door Peugeot 403 "Familiale" and "Commerciale" estate versions. The Familiale provided a third row of seats and was described as a 7/8 seater while the Commerciale offered a more conventional seat configuration for an estate car.
The lengthened 403 estate had a solid rear axle fitted to an aluminum differential case. It came with a manual column change gearbox and, in its "Familiale" guise, fully reclinable front seats. Sunroof and steel belted radial tires were standard. Reliability was considered excellent for the time.
A two-door cabriolet version of the car was also offered, with a luxurious interior featuring high quality leather upholstery. In 1958 the 403 cabriolet cost 80% more than the entry level "berline grand luxe" 403 sedan, and presumably for this reason the convertible 403 was produced and sold only in very modest numbers. In the spring of 1961 production of the 403 cabriolet came to an end, in anticipation of the launch later that year of the manufacturer's 404 Cabriolet.
In addition to Argentinian and Australian production, the local Volkswagen assembler in New Zealand built 1,033 Peugeot 403s in just under four years, beginning in March 1960.
Superseded by the Peugeot 404 in 1960, the 403 remained in production as a budget alternative until 1966.
