The need for an even cleaner burning diesel engine led to the creation of the 6.4 liter Power Stroke. The 6.4 is the quietest and cleanest diesel engine to ever power a Ford truck. This is also the first engine in the light duty diesel market to utilize twin turbochargers. The twin turbochargers provide quick spooling on acceleration and more than enough air flow in the higher RPM range. As the engine is reletively new to the market, little is still known. However, over 10 million miles of bench testing suggests this engine will keep Power Stroke legacy alive.

 

Interesting Facts:

- The 6.4 Liter Power Stroke is similar to the International Maxxforce 7. The The Maxxforce 7 is essentially the same engine as the 6.4 Power Stroke, but the "Power Stroke" name is only designated when the engine is used in Ford trucks. Power output and maximum RPM are the only significant differences between the engines.

- The 6.4 liter Power Stroke is the first of its breed to feature twin turbochargers, giving the 6.4 quick throttle response & plenty of airflow in the higher RPMs.

- The 6.4 liter Power Stroke is the cleanest and most powerful Power Stroke produced, featuring advanced emissions controls and peaking at 350 hp & 650 lb-ft of torque.

- International suggests that the 6.4 liter will prove to be the most durable Power Stroke ever produced.

- Due to the emissions controls, specifically the active regeneration mode (when the engine RPM is increased & fuel is injected into the exhaust system to burn off excess soot in the particulate filter), the 6.4 liter suffers from poor fuel mileage.
