Wheel end weight and friction reduction
Two main areas for fuel and CO2
emission reductions:
•
Reduce friction
to minimize energy losses. Can be done by e.g. improved bearings, seals and lubricants as well as optimizing the tire pressure while driving
•
Reduce weight
to minimize the mass that needs to be transported
