The kinetic energy recovery system (KERS) is designed to provide a 25 percent cut in fuel usage and carbon emissions.

Adgero describes its UltraBoost ST system as the world's first operational energy-saving, hybrid electric system for road transport. It works in a way similar to the kinetic recovery systems used in automotive racing, including GT and Formula One, with an axle-mounted unit underneath the cargo trailer converting slowing and braking energy into electricity that is stored in a bank of graphene-based ultracapacitors. When required, this energy is used to power the electrically-driven axle for a boost of acceleration, helping take some load off the engine of the truck pulling it.

An intelligent management system controls how the energy is recovered, stored, and re-used, with the system making use of a lightweight YASA motor to capture the kinetic energy usually lost as heat when braking. The system has been installed by SDC Trailers on a 13.6-meter (44.6-ft) curtainsider trailer that carries the livery of UK-based transportation company Eddie Stobart, which will be conducting road testing of the Adgero system.
