Engine cylinder capacity or CC is typically how we value the size of an engine. The bigger the CC, typically the more power the vehicle has.
More powerful vehicle's are usually more to insure. The reason why they are more is because drivers may choose to operate the vehicle at high speeds. Which reduces the customers ability to control a vehicle.
The Engine CC usually gets automatically loaded when you add the vehicle registration. Some occasions you may need to manually look up the vehicle and this is an area you will need to double check with the client. As different vehicle models, will have different CCs.
Electric cars have no engine CC.
