Volvo Trucks launches stop/start engine technology
5 November 2025
Volvo Trucks announced a new generation of its I-Roll technology, adding an engine stop/start functionality—claimed to be the world’s first in the heavy-duty truck industry—to reduce fuel consumption and CO2 emissions.
The technology, developed in-house at Volvo, is based on the company’s existing I-See and I-Roll technologies. The new stop/start engine feature is enabled by constantly monitoring road data and road curvature information. The engine will be turned off temporarily when an oncoming downward slope is identified along the route.
The new engine stop/start functionality is activated at speeds above 60 km/h. Depending on enabling conditions such as topography and ambient temperature, the new I-Roll with Engine stop/start will be able to cut up to one percent of fuel and CO2 emissions, according to Volvo.
The new feature will be offered on the Volvo FH and FH Aero with 13-liter diesel engine and customers can order it from November 2025.
