What does 'MPG' stand for?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

Miles per gallon

  1. A Miles per gear
  2. B Maximum power generated
  3. C Motor power gauge
  4. D Miles per gallon

Why this is the answer

MPG = Miles Per Gallon, the measure of fuel economy — how many miles a vehicle travels on one gallon of fuel. It is the standard US fuel-economy figure shown on a vehicle's window sticker and in the owner's manual (city, highway and combined). A higher MPG means the vehicle goes further on the same fuel. The distractors are invented expansions — 'miles per gear' and 'motor power gauge' are not real automotive terms, and 'maximum power generated' would be rated in horsepower, not MPG.
