Here's why:
* V6 engines can have different displacements. A 4.8-liter engine could be a V6, but it could also be a V8 or even a different configuration like a straight-six.
* Other engine configurations can also have 4.8-liter displacements. For example, a 4.8-liter V8 or a 4.8-liter straight-six engine would also be possible.
To determine if a 4.8-liter engine is a V6, you need additional information, such as:
* The make and model of the vehicle: Different car manufacturers use different engine configurations.
* The engine code or identifier: This is a specific code assigned to each engine type, which can tell you the configuration.
* The number of cylinders: A V6 engine will always have six cylinders.
Without more information, it's impossible to say for sure whether a 4.8-liter engine is a V6.
