How to Calculate MPG
Improving Your MPG

O Cálculo

Consumo = km percorridos ÷ litros abastecidos. Encha o tanque, zere o odômetro. No próximo abastecimento: km ÷ litros = km/L. 400 km com 35 litros = 11,4 km/L. O consumo declarado pela montadora (INMETRO/PBEV) é 10-20% melhor que o real.

Dicas no Brasil

Etanol vs gasolina: regra dos 70%. Pneus calibrados: economia de 2-3%. 120 vs 100 km/h: +15-20% de consumo. Ar-condicionado: +5-10%. Combinados: 20-30% de economia sem trocar de carro. O app Fuellio ajuda a acompanhar consumo real ao longo do tempo.
