it may be possible, but i doubt it's probable. there's almost no
similarity between the daf and honda systems. and i believe that the
moving cone gearing concept had been used on conveyor belts decades
before daf adapted it to automotive use, so i doubt honda or anyone else
would pay to license.
afaicfo, the main delay in adoption was reliability. daf belts used to
break regularly, and most people considered this to be a barrier to
ownership since the dealer used to charge so much for replacement. [i
think it was in fact a common industrial belt, so easy and cheap to get
if you knew where to look].
talking with people here in the u.s., they're very prejudiced against
cvt's, citing "but what if it breaks" as their reason. fact is, cvt's
are no less reliable and no harder to fix than traditional automatics,
and can in fact be more reliable since the controls are simpler. i
talked with a honda cvt owner a while back that had 300k on his, and
apart from the factory clutch recall, had had no issues with it. i
don't think he ever realized what kind of transmission it was and so
just drove it without worrying.
