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?
Show answer
Answer: C. Statement I is correct: full battery electric vehicles run only on a battery and electric motor. Statement II is correct: hydrogen fuel cell vehicles make electricity from hydrogen on board. Statement III is correct: fuel cell-electric hybrids combine a fuel cell with a battery. All three replace the conventional petrol or diesel engine, so all are alternative powertrain vehicles.
Watch for: The trap is thinking only battery EVs count; any non-conventional drive system is an alternative powertrain.
Why the other options are wrong
- A. Wrong: all three are alternative powertrains, not just one.
- B. Wrong: all three are alternative powertrains, not just two.
- D. Wrong: all three are alternative powertrains.
