The new Ford F-150 diesel will be the most fuel-efficient full-size pickup ever made when it goes on sale in May. The official EPA highway rating rating for 2WD trucks with the 3.0-liter turbodiesel V6 is 30 mpg on the highway and 22 mpg in the city, Ford announced on Thursday.

That makes it precisely as efficient as the smaller, diesel-powered Chevy Colorado midsize pickup. It also beats the most recent Ram 1500 diesel’s highway rating of 27 mpg, although an all-new one is on the way next year, as is a Chevrolet Silverado with a straight-six-cylinder turbodiesel engine.

Ford’s new motor comes with a 10-speed automatic transmission and puts out 250 hp and 440 lb-ft of torque, which the automaker says is good for up to an 11,400-pound tow rating and a maximum payload capacity of 2,020 pounds, depending on the configuration of the vehicle.

Ford predicts diesel-powered models to account for around 5 percent of F-150 sales, which translates to approximately 45,000 pickups, and has priced the option $2,400 higher than F-150’s 375 hp 3.5-liter EcoBoost V6.
