Is there a way to have fields or groups of fields be visible/invisible based on the choice of a picklist field.

For example if VehicleType is 'Car' then fields pertaining to Car such as NumberOfDoors, Transmission etc are visible

and if VehicleType is 'Bike" then fields pertaining to Bike are visible such as  HandleBarType,  BikeSeatType 

I would like to put all the fields of all the VehicleTypes in one object and have the appropriate fields be visible or not depending on what the user selects from the picklist.  

Is this possible?
