  4. Overdrive (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Overdrive_(mechanics)

    The power needed to propel a car at any given set of conditions and speed is straightforward to calculate, based primarily on the total weight and the vehicle's speed. These produce two primary forces slowing the car: rolling resistance and air drag. The former varies roughly with the speed of the vehicle, while the latter varies with the ...

    The wide gear span [a] allows the engine speed level to be lowered (downspeeding), which is a decisive factor in improving energy efficiency and thus reducing fuel consumption by 6.5 %. [10] In addition, the lower engine speed level improves the noise-vibration-harshness comfort and the exterior noise is reduced by up to 4 dB(A). [ 1 ]

  7. Steering ratio - Wikipedia

    en.wikipedia.org/wiki/Steering_ratio

    A steering ratio of x:y means that a turn of the steering wheel x degree(s) causes the wheel(s) to turn y degree(s). In most passenger cars , the ratio is between 12:1 and 20:1. For example, if one and a half turns of the steering wheel, 540 degrees, causes the inner & outer wheel to turn 35 and 30 degrees respectively, due to Ackermann ...

  9. Gear inches - Wikipedia

    en.wikipedia.org/wiki/Gear_inches

    Typical gear ratios on bicycles range from very low or light gearing around 20 gear inches (1.6 metres per revolution), via medium gearing around 70 gear inches (5.6 m), to very high or heavy gearing around 125 gear inches (10 m). As in a car, low gearing is for going up hills and high gearing is for going fast.
