How many kilometers has Volkswagen's fuel consumption dropped?

Volkswagen's average fuel consumption is generally 9.2~ 12.0L/ 100km.

Several factors affecting fuel consumption;

Road conditions: Generally, flat roads are more fuel-efficient than bumpy roads, straight roads are more fuel-efficient than detours, and flat roads are more fuel-efficient than traffic jams.

Weather: It is hot in summer, so air conditioning and refrigeration will consume some oil consumption. When the temperature is low in winter, the combustion temperature of gasoline can not reach the optimal temperature, and the combustion is incomplete, which will consume some fuel consumption.

Tire pressure: If the tire pressure is too low, the fuel consumption will increase.

Engine: engine surface stains and oil stains will affect engine heat dissipation, resulting in increased fuel consumption.

Carbon deposition in gearbox: Carbon deposition in gearbox will reduce engine power and increase fuel consumption to a certain extent, because obtaining the same power as before carbon deposition requires increasing throttle opening and corresponding fuel supply.
