Unfortunately, most cars today are built with far more powerful engines
than cars from that era. It seems that much of the efficiency
improvements of modern engines has been squandered by a drive for ever
more power rather than better and better fuel economy. At least a few
modern engines can be adapted to our Vanagons and of those few the
smaller ones can give us better fuel economy than our stock engines can,
at least for those with stock gasoline engine Vanagons.
