All 55s featured the unique Variomatic belt-driven continuously variable transmission, with no manual transmission available. This feature of all DAF cars was very unusual for its class at the time.
The 55 was available as a 2-door saloon, a 3-door estate and a 2-door coupe.
In total 164,231 DAF 55s have been built.
The 55 was developed to be a more powerful version of the 1966 DAF 44. The redesign was extensive, and featured the following major changes:
- For added safety a dual circuit brake system was fitted. All models also featured front disk brakes as opposed to the 44's drum brakes.
- The front panel was changed to provide room and airflow to the radiator.
The rest of the car featured detail trim changes to set it apart from the lesser 44. All this heightened performance to a 136 km/h top speed, and made for a more practical car.
The saloon was launched at the end of 1967, with the coupe version launched three months later, in March 1968. The coupe was overall more elegant than the saloon, featuring a gently sloping roof line, pillarless doors and a more upscale interior featuring reclining seats, carpet instead of the saloon's rubber mats and fake wood on the dashboard. Although the roof line turned it from a 4-seater into a 2+2, the coupe was a very successful model; 1 in 8 sold DAF 55s was a coupe.
In September 1968 the estate version became available. In August 1969 there was a minor facelift of the whole model range and a delivery version became available, essentially a 55 estate without a rear seat. After the success of the DAF 55 in the London-Sydney Marathon, the dealer option 'Marathon' package was introduced. The package meant that the dealer fitted an uprated suspension, and parts to upgrade the B110 engine to 65 bhp (48 kW).
In 1971 the factory version of this package was introduced, simply called the 55 Marathon. This did not feature an upgraded suspension, and had a 63 bhp (47 kW) 1108 cc engine, the BR110. This raised the top speed to 145 km/h. The 55 Marathon featured wider steel wheels, exterior striping and a brake booster was added for safety and comfort. The Marathon was available as a saloon or a coupe.
In 1971 the coupe received normal doors with pillars, since the earlier pillarless design proved to be leaky and noisy at speed.
The DAF factory was very involved in motorsport, to show the world that the Variomatic transmission was reliable as well as sporty. The 55 relieved the 44 in the works rally program, and had various successes. A 55 won the 1968 Alpine Rally, and in late 1968 Rob Slotemaker finished 17th out of 100 contestants in the grueling 16500 km London-Sydney Marathon. This remarkable success inspired the later 'Marathon' range offered by DAF. Because of the Variomatic and its function as a limited slip differential it was also popular with many privateers in the rally world. Jan de Rooy, of Paris Dakar fame, built his own 4-wheel drive version, with a mid mounted Ford BDA engine coupled to a special Variomatic, and campaigned it with great success on the international rallycross theatre throughout the early 1970s.
