Gear Ratio Calculation

WARNING: This page is about a different car, the 2016 Volkswagen Beetle, 2015 Volkswagen Beetle, 2014 Volkswagen Beetle, and 2013 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

Example:

	6th Gear	Final Drive
Drive gear	ZG₁ = 43	ZA₁ = 25
Driven gear	ZG₂ = 35	ZA₂ = 69

i = ZG₂ : ZG₁ GEAR RATIO CALCULATION => List Item:Z

i_G = gear ratio = ZG₂ : ZG₁ = 35 : 43 = 0.814

i_A = Axle ratio = ZG₂ : ZG₁ = 69 : 25 = 2, 760

i_total = total ratio= i_G x i_A = 0.814 x 2.760 = 2.247

Z₁ = Number of teeth on the drive gear, Z₂ = Number of teeth on the driven gear
