Never one to rest on its laurels, Ford is updating its Super Duty line. The 2015 Ford Super Duty pickup line includes a heavily reworked 2015 F-450, an updated F-Series Super Duty King Ranch model, and most importantly, extensive revisions to Ford's 6.7-liter Powerstroke turbodiesel V-8, designed to make it both more powerful and more reliable.

The big news for most 2015 Ford Super Duty buyers is the second generation of the Blue Oval's Powerstroke V-8. For 2015, Ford set out to make its big turbodiesel V-8 both more powerful and more reliable than before. Ford's Super Duty engineers were able to accomplish both tasks with one relatively simple change: slapping on a bigger turbocharger. The new turbocharger is 8.5 millimeters larger in diameter than before, which allows Ford to tune the Powerstroke to make more usable power, using less boost than before. That, in turn, meant Ford was able to eliminate the wastegate and its associated controls from the Powerstroke, making it simpler and more reliable. Ford has yet to announce power output for the second-generation Powerstroke V-8, noting only that it'll make more than the current Powerstroke's 400 hp and 800 lb-ft of torque.

In addition to the new power output and improved reliability, Ford boasts that high-altitude performance is also improved, as is engine exhaust braking, thanks to the larger turbocharger. Other changes Ford made to the second-generation Powerstroke include a new high-pressure fuel pump and fuel injectors, reduced friction on the engine's internals, and a new torque converter for the six-speed automatic that allows it to handle the extra power.

The rest of the 2015 Ford Super Duty lineup gets some changes too. The range-topping 2015 Super Duty King Ranch, for example, moves more upmarket with a more luxurious interior. The cabin now features higher-quality and visually lighter Mesa leather on the seats, center console lid, arm rests, and steering wheel. The "Running W" logo -- the same logo that the real life King Ranch uses to brand its cattle -- is more prominent than before, with it stitched into the seats and center console lid to make it appear as if the Super Duty itself were branded.

The F-Series Super Duty King Ranch's exterior gets a few updates as well, with its bumpers, lower body and wheel lip moldings now painted in metallic-brown "Caribou" paint, and the Running W on the wheel caps.

The 2015 Ford F-450 was also extensively updated, increasing its towing and hauling capability. The 2015 F-450's highlights include a strengthened frame, heavy duty rear leaf springs, and stronger shocks and stabilizer bars. "Commercial-grade" 19.5-inch wheels and tires also make an appearance on the 2015 F-450. Ford has also fit the 2015 F-450 with the F-450 chassis cab's stronger brakes, and re-calibrated its anti-lock braking system. The F-450's 6.7-liter Powerstroke (its only available engine) also gets unique engine calibration.

The 2015 Ford F-Series Super Duty is being introduced today (rather appropriately, we might add) at the Texas State Fair, and likely go on sale early next year.
