* 2.5L I4: A four-cylinder engine. This was a relatively common and generally fuel-efficient option.
* 3.0L V6: A six-cylinder engine that provided more power than the four-cylinder. This was a popular choice for those needing more towing or hauling capability.
There might have been some regional variations or less common engines offered, but the 2.5L I4 and 3.0L V6 were the dominant engines in the 2002 Ford Ranger lineup.
