Turbo Compounding

The SuperTruck program enabled Volvo engineers to refine the mechanics and aerodynamics of the new geartrain and turbine, ensuring peak efficiency in the “sweet spot” for Volvo’s integrated powertrain solution.

A new turbo compounding system was designed to recover this normally wasted energy on the 2017 Volvo D13 with Turbo Compound, helping boost fuel efficiency by up to 6.5 percent.

The patented wave piston, working in combination with Volvo’s other engine enhancements, delivers improved fuel efficiency of up to 2.2 percent for the D11 and 2.5 percent for the D13.
