 When it works, the 3.5L twin turbo V-6 known as the "Ecoboost" is amazing. 21+ mpg, 365 HP & 425 trq. A great combination of daily driver with nearly 10K tow capacity. First 55K miles were great, but the 2011 EB relies on multiple ECU "systems" to attain this peak performance, and if anything is not working perfectly, mileage, power, and driveability fall-off quickly. Ford still has not acknowledged any issues that do exist with the 2011 version of this motor. Humidity. Coils. Valvetrain rattles at startup. Hood shaking misfire at idle. Black on chrome tailpipe. I would not buy a 2011 EB again. Maybe 2014, now that the 2011 bugs Ford never admitted have been worked out. 2011 EB - Stay away!!
