i feel that japan car makers bother about fuel consumption is
because they themselves depend 95% on imports of raw materials and
stuff for their own country. thus they needa save $$ on such minor
things like fuel and stuff..
whereas, european countries and the states have no lack of fuel and
thus its very much cheaper for them and FC for their cars do not
really come into consideration while the car makers design the
engine and stuff..
it us USD$2 for 1 gallon..
its like $3.60 for 3.8L..
