FWIW, the DAF Daffodil used 2 belts, one for each rear axle. They used a
variable pulley system to control the drive ratio. It was called the
"Variomatic". Very smooth and very slow. The DAF had only 600 and 750cc
sedans. They were powered by a air cooled 2 cylinder 4 stroke engine.
The transmission was described as a continuously variable transmission.
Reverse was handled by a dog clutch in the primary gear case. Volvo
wound up taking over production and the DAF became the Volvo 66.
There is a Volvo web page that explains the mechanism in more detail.

I actually worked on three or four of these cars back in the '60s. They
were interesting technically but they didn't have any personality.
