* More power: Generally, a larger displacement engine will produce more horsepower and torque. This isn't always guaranteed as other factors like design, technology, and tuning play a role.
* More torque: Torque, or rotational force, is usually more significantly affected by displacement. A 4.7L engine will typically offer more torque at lower RPMs than a 4.0L. This translates to better pulling power for towing or hauling.
* Greater fuel consumption: Larger engines tend to consume more fuel, especially under heavy loads. The 4.7L will likely have a lower fuel efficiency rating than the 4.0L.
* Different physical size and weight: A 4.7L engine will be physically larger and heavier than a 4.0L engine.
However, it's crucial to understand that these are general trends. The actual performance difference between a specific 4.7L engine and a specific 4.0L engine depends on many factors including:
* Engine design: The architecture (V6, V8, inline), the number of valves per cylinder, the type of fuel injection, and other design features all significantly influence power and efficiency. A well-designed 4.0L could outperform a poorly designed 4.7L.
* Technology: Modern engine technologies like turbocharging or supercharging can drastically increase power output in a smaller displacement engine. A turbocharged 4.0L might exceed the power of a naturally aspirated 4.7L.
* Tuning: Engine tuning significantly impacts performance. A highly tuned 4.0L might outperform a stock 4.7L.
In short, while a 4.7L engine *generally* offers more power and torque than a 4.0L engine, you can't make a definitive statement without knowing the specifics of the engines being compared. The manufacturer, year of manufacture, and specific model all heavily influence the final performance characteristics.
