At Agritechnica, Deutz presented a range of concepts that combine practicality and innovation—from the new “TCD” and “TTCD” engine units for agricultural applications to the “TCD 2.2 HEV” hybrid system—without neglecting full electric solutions, featuring a new packaging designed for integration on self-propelled machines.
Deutz’s presence at Agritechnica 2025 was marked by a clear strategic choice: to focus on the evolution of the internal combustion engine, emphasizing technological pragmatism and the ability to meet the real needs of the off-road market.
This is a firm stance in an industrial landscape where the energy transition is progressing at different speeds and where diesel reliability and efficiency remain crucial for productivity and operating costs. Within this context, Deutz unveiled two new engine concepts representing a substantial evolution of its product range: the “TTCD 7.7 Agri Concept” and the “TCD 6.0,” engines that set a new benchmark for efficiency and modularity in agricultural and industrial applications.
The “TTCD 7.7 Agri Concept” is a six-cylinder engine with a 110-mm bore and 135-mm stroke, for a total displacement of 7.7 liters. It is based on a latest-generation platform featuring a structural crankcase. The engine delivers up to 280 kW (380 hp) at 2,200 rpm, with a maximum torque of 1,550 Nm available between 1,200 and 1,600 rpm. It can be configured with either a single or twin turbocharger, while electronically controlled common-rail injection optimizes combustion processes, improving specific efficiency and responsiveness under variable loads.
Alongside the 7.7-liter unit, Deutz also showcased the “TCD 6.0” concept, an inline six-cylinder 6-liter engine with two valves per cylinder operated by a single overhead camshaft. Engine is available in two configurations.
The first, equipped with a wastegate turbocharger, delivers 195 kW (265 hp) at 2,200 rpm with a peak torque of 1,050 Nm at 1,300 rpm. The second, higher-performance version delivers 221 kW (300 hp) at 2,300 rpm with 1,100 Nm of maximum torque at 1,400 rpm, achieved through a variable-geometry turbocharger. Certified to Stage V, the “TCD 6.0” does not use exhaust gas recirculation, simplifying thermal management and reducing maintenance costs. A further variant capable of reaching 260 kW is currently under development.
Completing the overview of new offerings displayed in Hannover was the recently launched “TCD 10.7,” a six-cylinder engine with a displacement of 10.7 liters, featuring cylinder liners with a 125-mm bore and 145-mm stroke. It is designed to cover a power range from 240 to 340 kW (326 to 462 hp) available at 1,600 rpm, with maximum torque figures of up to 2,200 Nm at 1,300 rpm.
Alternative solutions focused on sustainability and electrification were also presented. Among these, the hybrid version of the “TCD 2.2 HEV” stood out, interpreting the plug-in hybrid concept for off-road applications. Based on a three-cylinder 2.2-liter engine with a 92-mm bore and 110-mm stroke, the system combines a combustion engine delivering 55.5 kW (75 hp) at 2,600 rpm and 280 Nm of torque at 1,600 rpm with an electric module ranging from 40 to 80 kW, depending on configuration, for a total peak output of up to 130 kW (180 hp).
The system can operate in full-electric mode as well as in series or parallel hybrid modes, ensuring maximum application flexibility. Its modular powertrain architecture also allows integration on other engines in the range, such as the Deutz “2.9” and “4.0,” enabling a scalable approach tailored to operational needs.
At the top end of its electrification strategy, Deutz presented the “NewTech Component Frame,” a full-electric system architecture designed to handle a DC voltage range between 400 and 750 V and support charging capacities of up to 44 kW AC and 150 kW DC (200 A at 750 V). Engineered to manage electric motors delivering up to 300 kW continuously and 500 kW peak, the system integrates auxiliary components such as 7-kW cabin heaters, air-conditioning compressors, DC power outlets up to 4 kW, and electric or electro-hydraulic power steering systems.
Modular and scalable battery solutions complete Deutz’s technological portfolio. Available with capacities ranging from 31 to 400 kWh and voltage ranges between 48 and 850 V, they use either lithium iron phosphate (LFP) or nickel manganese cobalt (NMC) cells depending on application requirements, ensuring maximum compatibility and energy density.
