MAN's Final D30 Diesel Engine Marks the End of a Century-Long Legacy

MAN Truck & Bus introduces its last 13-liter D30 diesel engine in Nuremberg, closing over a century of diesel production. Discover its performance, eco-efficiency, and future impact.

MAN Truck & Bus has opened a new chapter in its history by launching the production of the 13-liter D30 diesel engine in Nuremberg. This engine will be the last diesel unit produced at the renowned plant, which has been manufacturing engines that set industry standards for more than a century.

Developed in collaboration with brands from the TRATON Group, the D30 is designed for heavy-duty MAN TGX and TGS trucks. With a power range from 380 to 560 horsepower and torque of up to 2800 Nm, the D30 sets new benchmarks for fuel efficiency and environmental performance. Its high-pressure Common Rail XPI injection system, with pressure up to 1800 bar, combined with a twin-turbocharger, delivers impressive performance while reducing fuel consumption by 4% compared to previous models. This improvement also leads to lower CO₂ emissions, which is particularly crucial in today’s regulatory landscape.

One key innovation is the absence of an exhaust gas recirculation (EGR) system, which helps reduce nitrogen oxide emissions without compromising efficiency. Paired with the advanced MAN TipMatic 14 automated gearbox — featuring 14 forward and 2 reverse gears — trucks equipped with the new engine offer smooth driving dynamics and outstanding fuel economy.

The project’s total investment amounts to approximately €220 million, with an additional €30 million allocated to crankshaft production in Salzgitter. However, the launch of the D30 is more than just another milestone in MAN’s evolution. It marks a symbolic transition toward cleaner technologies. MAN is already expanding its range of electric trucks and plans to introduce hydrogen-powered models in 2025, aligning with its goal to reduce CO₂ emissions and support the transportation sector’s decarbonization.

While bidding farewell to the diesel era in Nuremberg may evoke a sense of nostalgia, the new D30 proves that traditional internal combustion engines can still be more eco-friendly and efficient. This ensures that they will continue to play a significant role on Europe’s roads for years to come.
