we took a 240 mile trip (each way), at mostly 75-80 mph. We got about 32 mpg. To me 70-80 mph on the highway is 'real world' driving. So I'm satisfied with mid 30's figures. But for my situation, this is not a 47 mpg 'real world' car. We don't drive it like a hybrid. We drive it like a car (and enjoy it as not only a hybrid, but a car). Yes I understand a small portion of enthusiasts who post here can easily meet the EPA estimates, but I feel it's very situation specific. I'm also pretty confident I'd get better mpgs in a Prius, but I also understand that hitting 75+ mph in a Prius would be interesting to say the least. Our normal daily use is a 17 mile trip to work, mostly on the interstate. We seem to have levelled off at 38.3 mpg (we're at about 2500 lifetime miles). I agree that it takes a good 5 min to warm up and achieve reasonable mpgs.
