The ones we had were certainly inspired by DAF technology. Small rear wheel drive cars with belts (one each side) driving the rear axle instead of a drive shaft, and a novel (for the time) CVT. The ones we had had brand new bodies though that were bigger than and looked almost nothing like their spiritual DAF predecessor.
Fun little cars. I know CVT's get a bad rep these days, but they were amazing on those things. Very small displacement motors bin light cars with a CVT made them drive like fun little go-carts.
These cars are the main reason why I am waiting for someone to finally make another decent CVT.
I know it can be done well, because I've driven it, and why would you have these large heavy 8-12 speed automatic transmissions if you can make a good "infinite speed" CVT. Many modern implementations haven't exactly been inspiring though.
I looked it up. We had both of the 340 body styles. The original from 1980 on and the later one. The original DAF rebadge was apparently called the Volvo 66, and was a DAF 66 with a Volvo badge on it. I never saw too many of those though
