A "Car type" is the choice of a car that's available to book within your city or area.
Each Car type has its unique features, occupancy, and price to fit your needs.
There are permanent Car types, based on city, which are available at all times. There are also campaign specific Car types which are available only during promotional campaigns.
Selecting between the Car types is easy, by simply tapping on the Car type you wish to book, and you can find all Car type pricing and information here: Menu > Settings > Rates.
