The combustion engine continues to play an important role in Volvo Truck’s driveline strategy and its new engines offer a combination of more power, lower fuel consumption, lower emissions, lower noise and improved drivability.

The latest in-house developed engine platform is Volvo Trucks’ most fuel-efficient engine ever, delivering up to 4% lower fuel consumption versus the engine it is replacing. The new engines will cater for a wide variety of applications and will also meet or exceed the requirements of new legislation such as emission and noise levels.

“These all-new engines are not only our most fuel-efficient powertrains ever, but they will also take our combustion engine into the future,” says Jan Hjelmgren, Head of Product Management at Volvo Trucks.

“The flexibility and readiness for all existing diesel and gas fuels but also future hydrogen applications means that we can offer efficient trucks with the possibility of net zero emissions to all our customers globally.”

The new platform comes with upgraded engine brake functionality for increased drivability, new cylinder and turbo designs as well as an updated version of Volvo’s appreciated I-Shift transmission. Both the diesel and gas versions will also offer significantly higher torque levels.

Further, many variants of the diesel version of the new engine are compatible with Volvo Trucks’ I-Roll with engine stop/start functionality, which means that more customers can benefit from saving fuel and emissions by being able to turn off the engine and roll downhill.

The new engine platform is ready for alternative fuels such as biodiesel/B100, HVO, biogas/bio-LNG and green hydrogen.

The D13 engine will offer between 380-560hp of power and 1,800-2,900Nm of torque while the G13 gas version has 420-500hp and 2,400-2,800Nm.

The new Euro6 engines fulfil the new legal requirements NNR3 (New Noise Regulation Phase 3), and are built for legislation to come in the future

They will be offered in the Volvo FM, FMX, FH and FH Aero models. Sales will begin during the third quarter of 2026. The new engines will be launched step by step globally with the first markets being Europe, Morocco, Turkey and India, later followed by North and Latin America, Asia and Africa.

The new engines will initially be produced in Skövde, Sweden and the trucks are assembled in Tuve, Sweden and Ghent, Belgium.

Volvo Trucks plans to transition towards fossil-free transport to reach its net-zero emissions target by 2040 using a three-path technology strategy.

The approach is built on battery electric, fuel cell electric and combustion engines that run on renewable fuels like green hydrogen, biogas (bio-LNG), biodiesel, and HVO (hydrotreated vegetable oil).
