A GENUINE OVERDRIVE REDUCES FUEL CONSUMPTION
EIN ECHTER OVERDRIVE SENKT DEN KRAFTSTOFFVERBRAUCH
An overdrive is a faster transmission ratio which, compared to a direct gear with a ratio of 1:1, reduces the engine speed. If one were able to purchase an overdrive as an accessory, the following advantage might be expected; the fuel consumption at faster speeds would be noticeably lower, for even lively drivers value a comfortable noise level at high speeds. The fastest rear axle should not be selected, so that there always remain reserves of tractive force for use in conditions of extreme gradient or when pulling a trailer. The applicability of an overdrive to the two highest gears has the effect of a sensitive splinter-group gearbox at high speeds and increases performance on hilly roads as well as reducing fuel consumption at the same time.
