* 2.3L Duratec I4: This was a common engine choice.
* 3.0L Vulcan V6: A larger displacement engine option.
To know *exactly* which engine is in a specific 2006 Ford Escape, you'd need to check the vehicle's identification number (VIN) or look at the engine bay itself. The engine displacement (2.3L or 3.0L) will be clearly visible on the engine block.
