Confidence Findings on the Potential of 6x2 Axles

Executive Summary

Trucking Efficiency has found that North American tractor-trailer fleets can accrue multiple benefits from adopting 6x2 axle systems, and moving away from the much more widely used tandem 6x4s.

6x2 axles offer a number of benefits: they lower fuel consumption, vehicle weight, and maintenance expenses and, in some cases, improve stability. Adverse consequences include less traction due to only one drive axle and increased tire wear. The short-term concerns—higher upfront purchase cost and lower resale value—are expected to be mitigated over the next few years as buyers become more confident and scale is increased by higher demand. This will be especially true since 6x2 production is expected to double each year for the next three years.
