Volvo Trucks has introduced two new 13-litre combustion engines developed on a common in-house platform, aimed at improving fuel efficiency while supporting a broad range of alternative fuels across its heavy-duty truck portfolio.
Volvo Trucks has introduced two new 13-litre combustion engines developed on a common in-house platform, aimed at improving fuel efficiency while supporting a broad range of alternative fuels across its heavy-duty truck portfolio.
The new D13 diesel engine and G13 gas engine, announced on 12 May, will be available across the Volvo FM, FMX, FH, and FH Aero model ranges, with sales scheduled to begin in the third quarter of 2026. Both powertrains are compatible with renewable fuels such as biodiesel/B100, hydrotreated vegetable oil (HVO), biogas/bio-LNG, and are also engineered to support future hydrogen applications.
Production of the new engines will initially take place at Volvo Trucks’ manufacturing facility in Skövde, while vehicle assembly will occur in Tuve and Ghent. The rollout will begin in Europe, Morocco, Turkey, and India before expanding to North America, Asia, and South America.
Jan Hjelmgren stated that the new engines are the company’s most fuel-efficient combustion powertrains to date and are designed to support the future transition of internal combustion technology. He noted that compatibility with both conventional and renewable fuels, along with future hydrogen capability, gives customers a pathway toward net-zero emissions.
Fuel Efficiency and Performance Improvements
When combined with Volvo Trucks’ latest fuel-saving technologies, including Cruise Control I-See and I-Roll with engine stop/start functionality, the new D13 engine can reduce fuel consumption by up to 4% compared with the previous generation engine. The estimate is based on simulations using a Volvo FH 42-tonne, 500-horsepower vehicle operating under representative European driving conditions.
The Volvo Aero range, introduced in early 2024, had already delivered fuel savings of up to 5% over its predecessor, and the new engine platform is expected to extend these efficiency gains across a wider range of transport applications and operating segments.
The new platform also features enhanced engine braking capability for improved drivability, redesigned cylinders and turbochargers, and an updated version of Volvo’s I-Shift transmission system.
The D13 diesel engine delivers between 380 and 560 horsepower (hp) with torque outputs ranging from 1,800 to 2,900 Newton-metres (Nm). Meanwhile, the G13 gas engine produces between 420 and 500hp and torque levels of 2,400 to 2,800Nm.
Several variants of the diesel engine are also compatible with Volvo Trucks’ I-Roll system, which enables automatic engine stop/start functionality during downhill rolling to further reduce fuel consumption and emissions.
Both engines comply with Euro 6 Noise Regulation Phase 3 (NNR3) requirements and have been designed to meet anticipated future emissions legislation.
Volvo Trucks is targeting net-zero emissions by 2040 through a three-path technology strategy that includes battery-electric vehicles, fuel-cell electric trucks, and combustion engines operating on renewable fuels such as green hydrogen, biogas/bio-LNG, biodiesel, and HVO.
