If 68% of fuel is used accelerating mass. vs 14% for aero drag (city driving)
then (weight adding) aero takes a 5X second place to weight saving panview, so be careful not to get too carried away by easy aero mods unless you spend a LOT of time driving on freeways.
About 2% of the world average is freeway driving.
IMHO that's why car makers don't bother much with boat tails etc.
JohnForde is in fact on the the freeway more than in town.
But I'd still love to see before/after freeway AND city economy numbers..!?
