New 2010 Ford 4.4-liter diesel engine scooped!
Designed to offer comparable acceleration to the current 5.4-liter gasoline Triton, the new engine should be rated at about 330 hp and 420 lb-ft of torque. Fuel economy is expected to be around 20% better than the gas-fed Triton. To meet tough emission standards, a NOx after-treatment called "aqueous urea" will be injected into the hot exhaust stream. While the additive cleans up the tailpipe exhaust, it will also be another fluid the consumer will have to maintain (Ford is promising the "urea tank" will only need replenishing during oil changes).

A closer inspection of the placard also indicates 4.4-liter diesel will find a home in the next Lincoln Navigator and Ford Expedition — of course we're still wondering about those rumors we'd heard about the 5.4-liter Trition V8.
