I'm amazed that a mazda3 with an automatic can do so well. I've noticed that their car designs are generally pretty aerodynamic... i suppose it's not a big surprise.
I used to be a honda/nissan guy, but man.. Mazdas are that perfect combination of power, handling, good looks and efficiency. I'm surprised there aren't more threads on hypermiling them. Especially the newer ones with stupidly efficient direct injection motors.
