Probably not so much affect the power needed as power available, all
other things being equal.

I'm thinking that with a 10-12 hp VW van, absolutely /everything/
(even tidal force) becomes a critical factor. :-)

I remember driving my VW beetle into a light headwind on a straight
and level road with the "pedal to the metal" - and not being able to
go faster than 50 MPH...
