axle ratio
- The number of output shaft (on front-wheel-drive vehicles) or drive shaft (on rear-wheel-drive vehicles) revolutions required to rotate the axle one full turn
- For a rear-wheel-drive vehicle with an axle ratio of 3.55:1, the drive shaft would have to rotate 3.55 times to rotate the rear axle once. This is also known as the Final Drive Ratio
- Lower numeric axle ratios tend to be more fuel-efficient. Higher axle ratios deliver added torque for increased power for acceleration and trailer towing
- Front-wheel-drive vehicles employ an Axle Transfer Ratio, essentially a Final Drive Ratio.
