Our goal is high combustion efficiency! Early power you gain, your lower revs are revived and you can reach the speeds you want without putting too much pressure on the accelerator pedal.
Usually to reach the speed you have to press the pedal for more than half but with The Vacuum-Torsion System you need just a quarter pedal.
Since you regain the lost energy, when you take your foot off the accelerator pedal, your vehicle will not pile up as before, and your driving distance without gas will be longer.
