Helical gears are very efficient when used in a "straight" configuration, as spur gear substitutes. But when used as a crossed set, their efficiency drops dramatically, as low as 50%

Additionally, the primary reason for using helical gears in a car is their noise level. Helical gears have quite similar efficiencies to spur gears, but run much quieter, due to the more gradual engagement of the teeth.
