Volvo Trucks D13 and G13 — new combustion engines. More economical and powerful than their predecessors. The G13 will also be available for hydrogen.
Volvo Trucks is introducing new 13-liter engines suitable for diesel, HVO, biodiesel (Volvo D13), and LNG or bio-LNG (Volvo G13). These are Volvo’s most economical truck engines ever: they combine more power with lower fuel consumption, lower emissions, lower noise levels, and improved driving comfort. Tests *) showed a potential saving of 4% compared to the latest D13 diesel engines.
The G13 engine is particularly interesting because it will soon also be available as a hydrogen combustion engine. The G13 uses High Pressure Direct Injection (HPDI); a technology in which a small amount of ignition fuel is injected under high pressure to enable compression ignition before (bio-)LNG or hydrogen is added. As a result, performance is comparable to that of a diesel engine. They deliver higher energy efficiency, lower fuel consumption, and more engine power than conventional gas and hydrogen combustion engines.
As a user, you can switch freely between biodiesel and fossil diesel (D13) or between LNG and bio-LNG (G13). However, you cannot convert a G13 to hydrogen. You must order it separately as a hydrogen engine.
The new engines have power outputs between 380 and 560 hp (diesel) or 420-500 hp (gas). They meet, and even exceed, the requirements of new legislation regarding emissions and noise levels.
The popular Volvo FH Aero series consumes up to 5% less fuel than the standard FH. On top of that, the new in-house developed engines provide additional fuel savings of up to 4% *) across a wide range of applications and segments. The engine platform features a refined engine brake function for increased driving comfort, new cylinder and turbo designs, and an updated version of the popular Volvo I‑Shift gearbox. Furthermore, both the diesel and gas variants deliver significantly higher torque.
In addition, many variants of the diesel engine are compatible with Volvo Trucks I‑Roll with stop-start engine technology.

– the new Volvo engines comply with the new NNR3 (New Noise Regulation Phase 3) legal requirements and are prepared for future legislation
– available on the FM, FMX, FH and FH Aero
– sales start in the third quarter of 2026
– introduction begins in Europe, Morocco, Turkey and India, followed by North and Latin America, Asia and Africa
– production of the engines takes place in Skövde (Sweden); the trucks are assembled in Tuve (Gothenburg, Sweden) and Ghent (Belgium)
– the FH16 is supplied with a 17-liter diesel engine (D17) with 600, 700 or 780 hp
*) Example based on simulations of a Volvo FH 4×2T 500 hp with a GVW of 35 tonnes, equipped with the new D13 engine and using Cruise Control, I‑See and I‑Roll with stop-start engine technology, compared to the previous standard D13 eSCR engine, under representative European driving conditions. Actual fuel consumption may vary depending on, among other things, driving speed, use of cruise control, vehicle specification, load, topography, driver experience, vehicle maintenance condition and weather conditions.
