Not only DAF usd a Variomatic Drive. Audi use(d) a similar system on their Multitronic. And most of the John Deer combine harvesters in the 70's had a variable speed system with V-belt drive. I would strongly recommend that Morgan does NOT use this kind of system. As they reach their limitations at the simple drive belt of the M3W they should not even think about a variable one!
