There is no more popular pickup truck in the world than the Ford F-series. The reasons are easy to see: no other pickup enjoys the reliability, the reputation, the capability, and—most of all—the legacy of the Ford F-Series. And now a new version was recently announced at the State Fair of Texas: the 2015 Ford F-Series Super Duty line.

Among the features that will set the 2015 F-Series Super Duty apart at a Louisville Ford dealer is its improved 6.7-liter Power Stroke V8 turbo diesel engine. This incredible powerplant, which debuted in 2010, has been one of the most successful diesel motors in the heavy-duty truck market. Part of the reason is that Ford remains the only manufacturer designing and building its own diesel engine for its trucks. This one has been amped up with a new GT37 turbocharger, which helps the engine produce more power more efficiently.

But there’s more than just power at stake with the new F-Series pickup truck. With the new 2015 lineup, improvements also include design. That’s why there will be an exclusive 2015 Ford F-Series Super Duty King Ranch edition, which includes a cut and stitched King Ranch logo from the ranch itself sewn into the leather, along with Mesa leather trim and accents on the interior, and a new, dark Caribou paint accent around the wheels and trim. This will keep the 2015 King Ranch edition one of the most distinctive pickups on the road.

Finally, the 2015 F-Series Super Duty lineup will address a major concern for drivers: fuel efficiency. This pickup will enjoy improved fuel economy for several reasons, among them the GT37 turbocharging technology mentioned above. Also, the fuel system has been enhanced with a high-pressure pump and exhaust temperature monitors, which inform computers that fine-tune the engine on the fly for power when you want it, and fuel efficiency when you’re not using it.
