Although the optional 4.6-liter V8 engine is rated 231 horsepower and 293 foot?pounds of torque, we don't think it's as good a performer in many respects as the small V8 engines from GM and Dodge, most of which are larger in displacement. It's a good, solid engine, with millions of examples on the road, and it sounds good at full throttle, but we find it a little anemic for all-around street use, and we would certainly find it wanting if we had to haul anything heavy or tow a trailer up a mountain road. For any customer contemplating those kinds of duties, the 5.4-liter V8 engine is a much better choice.
