If a vehicle you are entering into the P11D Organiser is a hybrid car, it needs to be treated as either Hybrid Petrol or Hybrid Diesel cars for this purpose - these SHOULD NOT be marked as electric. If it is a hybrid car, it will also be necessary to have a CO2 figure. The destinction between the Petrol and the Diesel element of the hybrid is used for applying advisory fuel rates, where appropriate when calculating mileage payment benefits.
