FAQs

Q1: How much range can a low-friction hub realistically add? 

A: Figures vary widely by supplier and vehicle. One published example claims a hub with about 66 percent lower rotational friction improves BEV energy efficiency by 0.76 percent and adds roughly 2.2 km of range on a full charge. Another supplier reports up to 30 percent less friction with an estimated 0.6 percent range extension.

Q2: Why do some suppliers claim much larger range gains from bearings? 

A: Claims often depend on which component and which baseline is used. One manufacturer states that reducing a key bearing's torque from about 1.5 Nm to below 0.8 Nm could potentially add nearly 30 km of range, and that combined friction-reduction technologies contributed over 5 percent range improvement. Such numbers should be checked against the specific vehicle and test cycle.

Q3: Why can a new tri-row hub design improve both stability and efficiency? 

A: One production example uses three rows of balls and face splines, cutting weight from 5.0 kg to 3.8 kg, raising stiffness by about 60 percent versus a twin-row design, reducing rolling resistance from 0.85 Nm to 0.6 Nm, and increasing wheel-end drive torque capacity by 50 percent.
