Lower average RPM = lower fuel consumption
Put simply, an engine's fuel consumption depends primarily on two factors:
One relevant factor is the engine's cubic capacity. Or in other words, the size and number of cylinders, which are filled with fuel during the injection phase. The other determining factor is the frequency (=RPM) at which the cylinders are filled with fuel. Driving with a lower average RPM, in other words in higher gears, improves your fuel economy. That's the secret of our fuel-saving technology. SHOW MORE
