In a conventional gearbox, with the same engine torque, which forward gear usually multiplies it least at the wheels?

Correct answer

The highest or tallest gear.

The highest or tallest gear usually multiplies torque less than lower gears. At equal engine rpm it permits higher theoretical wheel speed, but does not guarantee the highest actual speed: that depends on available power and resistance. Do not confuse a higher gear with a numerically larger reduction ratio; first gear usually has greater reduction and torque multiplication.
