DAF 55 Marathon
The DAF 55 Marathon represents one of the most unusual and innovative cars of the 1960s. While the basic DAF 55 sedan was an ordinary economy car, the Marathon coupe variant combined sporty styling with DAF's revolutionary Variomatic continuously variable transmission to create something genuinely unique. DAF's innovation was born of necessity – the Dutch truck manufacturer entered car production in 1958 with simple, economical vehicles. The Variomatic CVT system, using rubber belts and variable-diameter pulleys, provided infinite gear ratios between a minimum and maximum, eliminating traditional gears entirely. This made the car incredibly easy to drive with just two pedals (no clutch) and seamless acceleration without gear changes. The Marathon variant, introduced in 1967, featured distinctive fastback coupe styling that differentiated it from the sedan. The sleek roofline and integrated rear window gave it a modern, sporting appearance. The lightweight fiberglass body panels helped keep weight to just 740 kg. Under the rear bodywork sat an air-cooled flat-twin engine, enlarged to 1,108cc in the 55 series and producing 50 horsepower. The horizontally-opposed twin-cylinder layout was smooth for a two-cylinder and air-cooling eliminated the weight and complexity of a cooling system. The distinctive flat-twin sound was unique. The Variomatic transmission was the Marathon's defining feature. In normal driving, it provided seamless acceleration with the engine maintaining optimal rpm for the driving conditions. The system worked remarkably well, providing smooth, effortless progress without the jerky gear changes of contemporary automatics. The handling was surprisingly capable, with the rear-engine layout providing excellent traction and the light weight making the car nimble and responsive. The steering was quick and communicative. The Marathon's suspension used independent coil springs all around, providing a compliant ride despite the short wheelbase. What truly shocked the automotive world was the Marathon's rallying success. Despite modest power, the combination of light weight, excellent traction, and the Variomatic's ability to maintain optimal engine rpm made it competitive in its class. DAF Marathons won numerous rallies and hill climbs in the late 1960s and early 1970s, punching well above their weight. Inside, the Marathon featured simple but functional accommodations with supportive front seats, basic instrumentation, and adequate space for two adults. The rear seat was cramped. Build quality was decent though not exceptional. Today, the DAF 55 Marathon is appreciated by enthusiasts who value its unconventional engineering and David-versus-Goliath rallying heritage. The Variomatic transmission remains fascinating to experience, providing a driving experience unlike any other classic car. Values remain reasonable, making it an affordable entry into quirky classic car ownership.
The fiberglass body resists rust but check for stress cracks and poor repairs. The flat-twin engine is simple but requires regular maintenance – verify cooling fins are clean and engine doesn't overheat. The Variomatic transmission is reliable but rubber belts wear and eventually break. Replacement belts are available through DAF specialists. Check for oil leaks from the engine and transmission. Electrical systems are basic but wiring can deteriorate. Interior trim is often worn. Parts availability requires specialist suppliers in the Netherlands. Look for documented service history and avoid modified examples. Original Marathon specification is increasingly rare.
The DAF 55 Marathon was produced from 1967-1972 as the sporty coupe variant of the 55 line. Exact production figures are unknown but estimates suggest fewer than 5,000 Marathons were built. All were manufactured at DAF's Born facility in the Netherlands. The Marathon name referenced its intended use in long-distance rallying.
