Volvo Trucks enhances its I-Roll technology with stop/start functionality
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 on top of already achieved savings. 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.
Volvo Trucks introduces a new generation of its I-Roll technology, adding an engine stop/start functionality, a world first in the heavy-duty truck industry, according to the Swedish truckmaker. The new stop/start function is expected to cut fuel consumption and CO2 emissions.
More into details, 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. While the engine is turned off, zero fuel will be consumed and consequently, there will be no CO2 tailpipe emissions.
