21.61 mpg a few weeks after I bought it (out of almost 26K now). Driving it like a hooligan never letting it get below 2K rpm.
Combined for Los Angeles traffic (including 1 hour of rush hour traffic jam per day) is 25 mpg. 30+ on long road trips.
Note - I have a V6 with the base package, manual transmission, and stock (tall) gears. It's plenty fast once you get it above 2500 rpm. The manual/base trim combo is the way to get econobox mpg out of these things. Given the mpg I get, I'm not impressed by the upcoming ecoboost.
