Consider the following types of vehicles: I. Full battery electric vehicles II. Hydrogen fuel cell vehicles III. Fuel cell electric hybrid vehicles How many of the above are considered as alternative (powertrain) vehicles?
Correct answer: C
Explanation
Alternative powertrain vehicles are those that do not use conventional petrol/diesel engines. Instead, they rely on clean energy sources like electricity or hydrogen.
* I. BEVs – Run fully on batteries and electric motors. * II. FCEVs – Use hydrogen to make electricity via a fuel cell. * III. FCEHVs – Combine hydrogen fuel cell + battery + electric motor.
All three are alternatives to traditional fuel vehicles.
