Ford Motor Company announced this morning that when the 2015 Ford F Series Super Duty pickups begin hitting dealerships around the country, they will feature a massive new high tech turbocharger that will make the Super Duty more powerful, more capable and more efficient than ever before.

The current Ford F Series Super Duty pickup powered by the 6.7L PowerStroke diesel V8 is among the most powerful engines available with 400 horsepower and 800lb-ft of torque but this monster mill falls a bit short of the 6.7L Cummins Turbo Diesel I6 that packs 385 horsepower and 850lb-ft of torque under the hood of the Ram 3500. In an effort to close that gap, Ford has revamped their PowerStroke V8 for the 2015 model year and while the Motor Company hasn’t quoted any exact power figures for the 2015 Super Duty – Ford has promised that the new PowerStroke will offer more power than the current heavy duty diesel engine.

“Truck leadership means never resting, and the Super Duty team has been tireless in finding ways to improve the industry’s most popular heavy-duty pickups,” said Joe Hinrichs, executive vice president and president of The Americas, Ford Motor Company. “Super Duty diesel customers will benefit from improved performance and features backed by outstanding Built Ford Tough durability.”

To help beef up the 2015 Ford F Series Super Duty, Ford engineers made a variety of changes to the tried and true 6.7L PowerStroke diesel V8 that would not only make it more powerful but this new engine is also more efficient and more durable than the outgoing version. The most significant upgrade is the new GT37 turbocharger that sits atop the engine in a unique layout that helps to maximize the efficiency of the whole system. The GT37 turbo unit features a larger, single sided 88 millimeter compressor setup that replaces the smaller dual compressor setup that is used on the current Super Duty diesel engines. The “hot” side of the turbo that uses the escaping exhaust gases to spin the compressor wheel has also been increased in size, jumping from 64 millimeters in the current PowerStroke V8 to 72.5 millimeters in the 2015 models. This larger turbine creates more surface area for the exhaust gases to spin the turbo and more spin equals more boost…and more boost equals more power. At the same time, Ford expects that this new 2015 Super Duty engine will offer best in class fuel economy among diesel engines while also being one of the most powerful.

“The original designers of the current Power Stroke V8 diesel forecasted needs for higher output. This facilitated the larger turbocharger, increasing airflow and creating more power,” said David Ives, Power Stroke technical specialist. “We’ve dramatically improved performance while reducing overall engine complexity by focusing on the turbo system.”
