It looks like the new powertrain in the F150 was worth the wait, as some publications have begun to release information regarding its fuel economy. It looks like its going to deliver the best in class fuel economy, with 30mpg on the highway! The full breakdown is 22 in the city and 25 combined. Ford neglected to mention which specification achieved these results, but its a safe bet to assume they used the smallest, lightest version of the F150- likely a single cab, two wheel drive model. Another important note is that the diesel features an impressive 11,000lb towing capacity and a 1,900lb payload when spec'd correctly.
