A slightly more potent version of the 4.8L, offering a modest boost in responsiveness. Still best suited for lighter duties, but with added 4WD and FlexFuel versatility.
Fuel Economy
Fuel economy remains a weak point, with the small power increase not translating to better efficiency. E85 use will further reduce range.
