We have over 9000 miles on our 400h and get 25 - 27 mpg per tank. I drive 32 miles RT to work, half of it on the LA freeways. I've been able to get over 32 mpg right after filling up and getting directly on the freeway, usually driving about 62 - 63 miles per hour, but the surface streets really lower it. We're satisfied with the mpg - EPA estimates are always unrealistic!
