The first-ever Ford F-150 equipped with a Power Stroke diesel engine will offer an EPA-estimated fuel economy of  30 mpg highway, 22 mpg city and 25 mpg combined.

Ford claims that these figures are the highest EPA-estimated ratings available in a full-size pickup truck right now.

In addition to the F-150’s leading fuel economy ratings, the diesel-powered truck also offers best-in-class diesel power as the 3.0-liter Power Stroke unit produces 250hp and 440lb-ft of torque.

“Even a few years ago, customers wouldn’t have imagined an EPA-estimated rating of 30 mpg highway would be possible in a full-size pickup, but our team of crazy-smart engineers rose to the challenge,” said Hau Thai-Tang, Ford executive vice president, product development and purchasing.

The new 3.0-liter Power Stroke diesel engine was designed by the same team behind the Super Duty’s 6.7-liter Power Stroke V8. It features a variable geometry turbocharger and common-rail injection and offers peak torque from just 1,750rpm. A 10-speed automatic transmission is standard fit.

Towing is rated at 11,400 pounds while payload is 2,020 pounds in the XL and XLT fleet models and 1,940 pounds in the retail ones.

Ford says that the first F-150 Power Stroke models will begin shipping to dealers in May.
