Which of the following is NOT a valid advantage of an electric car?

  • A.Low carbon emission
  • B.High energy efficiency
  • C.Low maintenance
  • D.Refuelling time (Charging time) is less than that of gas-based car

Answer: D

An electric car has low carbon emission at the point of use, a high energy efficiency (a motor and battery turn most of the stored energy into motion) and low maintenance because it has fewer moving parts, no engine oil and no exhaust system. These are all real advantages.


But charging a battery takes much longer than filling a tank with petrol or gas, which takes only a few minutes, so a shorter refuelling time is not an advantage of an electric car. The answer is option D.
