1972 - 1988
- The Peugeot 104 is a supermini motor car designed by Paolo Martin and produced by the French car manufacturer Peugeot between 1972 and 1988.
- Saloon launch 1972
On its launch in 1972, the Peugeot 104 was offered as a four-door saloon, with a sloping rear end that suggested a hatchback. Power was provided from a 1.0L Douvrin engines / PSA X engine, (all aluminium alloy, chain driven overhead cam, with gearbox in the sump, sharing engine oil, mounted almost on its side), which was jointly developed with Renault. This transmission-in-sump arrangement was similar to that pioneered by the British Motor Corporation in the Mini. It gave good levels of economy and refinement as well as having an impressive chassis which made ride and handling excellent. - Coupé launch 1974
A three-door coupé was launched on a shortened chassis, with the same 1.0L engine as the saloon. Headlights were larger and rectangular in shape, rather than square. - 1976 facelift
A facelift in July 1976 saw the four-door saloon replaced with a five-door hatchback. Rear light clusters were modified slightly with indicators that wrapped around to the sides of the car, and a 1.1L engine was also made available. The coupé was made available in two versions, ZS and ZL. A modified camshaft on the 954 cc engines also retarded the valve timing in order to favour fuel economy at the price of a slight power reduction. The revised models only appeared in right-hand drive form at the end of the year. - 1978 facelift
The coupé gained a third variant, the ZA, and all coupé variants were given large rear light clusters with integral reversing lights. Higher specification 5-door models gained the larger headlights and grille introduced for the coupé. - 1980 facelift
The 1980 facelift was minor, with model designations changing in line with other vehicles in the Peugeot line-up. However, a 1.2L engine was now offered. - 1982 facelift
This facelift incorporated smaller headlights, a new grille and rear light clusters that included reversing lights. The amount of chrome trim was reduced and generally replaced by black plastic. The ZS coupé variant was given an 80 bhp 1.4L engine to improve its performance. - 1983 on
In 1983, the number of models offered was reduced to make way for the new 205. Production ceased in 1988. - Prototypes
Several prototypes based on the 104 are known to exist. Different power sources were tried out, including electric and diesel. The M18 prototype (circa 1976) was a blue 5-door estate, with rear light clusters similar to those that were used on the 504 estate. The M23 was a dark red 3-door van concept based on the saloon rather than the existing 3-door coupé. A yellow three-box saloon is also known, as is a white pick-up truck. - Citroën LN / LNA
By 1975, Peugeot had taken over Citroën (forming the PSA Group), and the 104 coupé bodyshell then formed the basis of the 602 cc two-cylinder engined Citroën LN. In 1982 this car was fitted with the more modern 652 cc engine of the Visa in 1983 to become the LNA, before production finally ceased in 1985. - Citroën Visa
The mechanical configuration of the 104 (with longer travel suspension), was also used in the Citroën Visa, leading to the abandonment of the Citroën Prototype Y plan for the Visa, although that plan went on to be used on Romanian-built cars. The Visa, unlike the LN / LNA, had its own distinctive body style and packaging. - Talbot Samba
A derivative of the 104 coupé with a slightly longer rear section, the Talbot Samba was launched in 1981, following Peugeot's acquisition of Chrysler Europe (and its Talbot marque) in 1978. A cabriolet version of the Samba was developed.
