Pickuptrucks.com has an extensive look at the new diesel mill for the 2011 Ford Super Duty. The new engine was developed entirely in-house after Ford's falling-out with Navistar.

The motor is a significant departure from previous Powerstrokes, in no small part because of stringent emissions requirements coming in 2011.

For starters, the air path through the motor has been reversed, dumping exhaust from both heads into a single turbo mounted in the valley.

The motor also uses two separate cooling systems, each with its own radiator and water pump. The primary system runs at 192F and cools the motor. A secondary system running at 122F cools the EGR, fuel, transmission, and a water/air charge cooler used in place of a traditional air/air intercooler.
