According to KGP, the new engine should be capable of a 9% increase in power and a 15% increase in torque relative to the 5.4-liter gas V8. According to this leaked report, the gas V8 should be capable of 320 HP and 390 lb-ft of torque. Jalopnik Snap Judgment: Doing the math, this would put the diesel V8 at approximately 350 HP and 450 lb-ft of torque, while still achieving 20% fuel economy. Let's hope sources and calculators don't lie.
20 percent fuel economy saving is not enough, if the price premium for diesel over gasoline holds over the long term. I was hoping for a four or six on the order of 200-250hp 300-350ft-lb and a 33 percent economy increase.
