The new e-optimized trailer builds on the established Kögel Light Plus lightweight chassis, but incorporates a critical technical modification: the wheelbase between the kingpin and the first trailer axle has been shortened by 12 inches (30 cm). This adjustment shifts the weight distribution to reduce the load on the tractor's drive axle.

According to Kögel, this modification reduces drive-axle pressure by up to two tons compared to conventional curtainside trailers. Depending on the specific electric tractor being used, carriers can achieve up to four tons of additional payload over a standard trailer setup. Furthermore, if the trailer is equipped with a dynamic wheelbase control system, the payload capacity can be increased by approximately one additional ton.
