The Volvo 66 is an automobile developed from the DAF 66, which was originally styled by Giovanni Michelotti.

The Volvo version of the car was slightly restyled and given larger bumpers compared with those of the original DAF model.

Although this was in keeping with Volvo's emphasis on safety, it also increased its cost of production.

It has different seats featuring headrests, a safety steering wheel, steel side-impact bars in the doors, and a de-clutching servo which enabled the driver to change gear with the choke engaged (In the older DAF models this was not possible, because the increased idle caused the centrifugal clutch to engage).

The majority were sold in continental Europe rather than in Sweden, where the car was never accepted by traditional Volvo buyers.
