Glöm inte bort Williams-bilen som hade en utvecklad variant av DAFs gummisnoddslåda. Tekniken kapade omkring en sekund på varvtiderna o förbjöds omgående. Den aktiva fjärdringen på samma bil fastnade även den i regelverket o förbjöds:

"The second one was the continuously variable belt transmission (CVT) pioneered and patented by Hub and Wim van Doorne's company Van Doorne's Transmissie (VDT). This innovation was borne by the other characteristic of the late fifties and early sixties: the breakthrough of mass production combined with levels of welfare that hadn't yet scaled the heights they would reach in the seventies. Thus, the Dutchmen's main ambition was creating a cheap and simple motor car that would democratize car ownership. For this, the Eindhoven residents' Van Doorne's Automobiel Fabriek (DAF), a manufacturer of military trucks since 1949, was to build a new generation of small-sized family cars powered by their brilliant "Variomatic" invention. The cars made a spectacular debut at the Amsterdam auto show of 1958. In time, it was also decided to add a competitions department to prove the technology's mettle in a strenuous environment, but ultimately the factory's rally and endurance activities were far more successful than its halfhearted forays into circuit racing. Still, Variomatic single-seaters won races and the system made an unexpected comeback in 1993, when David Coulthard tested a Williams FW15C paired with a "Transmatic" CVT jointly developed by VDT (separated from truck manufacturer DAF, and currently a Bosch subsidiary) and Patrick Head. This was done to such great effect that the FIA promptly banned the technology from 1994 on, just as it had earlier banned four-wheel drive, six-wheeled cars and turbines. "
