The need for an even cleaner burning diesel engine led to the creation of the 6.4 liter Power Stroke. The 6.4L is the quieter & cleaner than its predecessors. This is also the first engine in the light duty diesel market to utilize twin turbochargers, which provide quick spooling on acceleration and more than enough air flow to maintain performance in the upper rpm range. Though the emissions equipment hinders this Power Stroke's fuel economy, the engine has proven itself in strength and reliability.
