We were the first manufacturer to commit to e-mobility in heavy-duty trucks. Today, we have electric vehicles in customer use in all segments. 

A global platform architecture is used for both drive technologies: the ePowertrain. This allows for important economies of scale to be realized, because regardless of whether battery or hydrogen, the essential components of the architecture for the ePowertrain remain the same. 

Today, Daimler Truck already has 10 battery-electric vehicles in series production worldwide. By end of 2024, another one will be added with the Mercedes-Benz eActros 600.

Daimler has been working on drive technologies based on hydrogen for more than 30 years. To date the company’s fuel cell vehicles (cars and trucks) have traveled many millions of kilometers, demonstrating the marketability of this drive concept. In order to get the hydrogen drive into series production as soon as possible, Daimler Truck is making large investments. 

One of these investments resulted in the establishing cellcentric, a joint venture with Volvo Group, which will put one of Europe’s largest production facilities for fuel-cells in operation. Since 2021, first prototypes of the Mercedes-Benz GenH2 Truck are undergoing rigorous testing and have  demonstrated their capabilities at the Brenner Pass, one of Europe's busiest and most challenging transit routes and in a #HydrogenRecordRun exceeding the target range of 1000+ km on one tank filing of liquid hydrogen. 

The next steps are as follows: First fuel-cell trucks are expected to be tested in customer hands in the coming years. In addition, Daimler Truck is also investigating the hydrogen combustion engine, so far exclusively for pre-development purposes on the basis of basic technical studies and on the basis of a first Unimog prototype vehicle built up as part of the publicly funded German research project “WaVe”. Initial results from this show that the hydrogen combustion engine could definitely be a sensible, complementary solution for decarbonizing Daimler Truck’s powertrain portfolio. In the second half of the 2020s, Daimler Truck wants to add hydrogen-powered trucks to its series production portfolio.  

In contrast to trucks, Daimler Buses is taking the first step towards fuel cell drive in local transport, i.e. city buses. Their routes, operations, and energy supply can be planned in concrete terms and thus quite predictable. The all-electric Mercedes-Benz eCitaro with a fuel cell as a range extender is currently under development. 

Natural gas is a fossil fuel - and therefore it is at most a transitional technology on our way to CO₂-neutral transport.

Truly CO₂-neutral transport only works with battery electric or hydrogen-based drive. That's why Daimler Truck is consistently focusing on battery electric and hydrogen-powered commercial vehicles that can drive locally CO₂-neutral.

All of our important truck engines of the latest generation can be fueled with alternative, so-called bio fuels according to the EU standard prEN 15940. These include the subgroups Hydrotreated Vegetable Oil (HVO), Biomass To Liquid (BTL), Gas To Liquid (GTL), Coal To Liquid (CTL). These consist of a variety of resources that are being converted to fuels through chemical processes.

Since the characteristics of these fuels according to norm prEN 15940 mean that they are absolutely comparable to conventionally produced petroleum-based diesel fuel, no modifications to the engines or their peripherals are necessary.

Daimler Truck is focused on developing solutions that have great potential for worldwide implementation. Due to the high infrastructure costs involved, and also considering of the rapid development of battery and fuel cell technology, the company we do not see potential in catenary trucks at present.

Daimler Truck is not against catenary trucks, but for realistic and timely solutions. We are convinced that with the battery electric truck we have a flexible and already available concept for the respective field of application - without expensive, time-consuming and lengthy planning measures. The eActros is already in series production. Yet, with the eActros, we will do a comparison test with the overhead line project eWayBW in the so-called Murgtal in the region around the city of Rastatt in southern Germany.

In public transport, there is no single customer scenario for electric buses – the use cases vary, for example depending on the range and topography. Thus, we want to give our customers choices and meet their needs best.

Our all-battery electric Mercedes-Benz eCitaro city bus has been in series production since 2018. Since 2023, the vehicle has also been available with a hydrogen-based fuel cell as a range extender.

Our electric bus also offers different ways of charging technology, meeting individual requirements of the transport companies. Innovative thermal management ensures efficient energy consumption and forms the basis for a practical range. More information on our product portfolio can be found here.

Our first battery-electric intercity bus, the Mercedes-Benz eIntouro, is planned to follow from 2026.

The battery-electric Mercedes-Benz eCitaro fuel cell city bus with a hydrogen-based fuel cell as range extender can operate exclusively with hydrogen using a special operating mode. The vehicle can thus be used completely independently of any electric charging infrastructure. When the eCitaro fuel cell is operated exclusively with hydrogen, the fuel cell takes over all battery charging processes. This enables a new operating mode that can be flexibly selected by the customer. Stationary charging of the battery via the mains supply is no longer necessary. The battery and the fuel cell remain the main energy source for the drive. Depending on the battery generation, ranges of up to 480 kilometers^[1] can be achieved. This means that the eCitaro fuel cell can meet the requirements of transport operators who prefer to use green hydrogen instead of mains electricity as an energy source. 

_{[1] The range was determined internally under specific conditions, including equipment with maximum battery capacity and H2 capacity, battery in as-delivered condition, in typical city bus operation and in a moderate weather scenario, and may, for example, deviate from the values determined in accordance with Regulation (EU) 2017/2400. The actual range depends on the individual use of the vehicle, the vehicle configuration and other external factors. The actual range may therefore be below or above the specified value.}

The Mercedes-Benz Citaro hybrid is available in a variety of model variants of the best-selling city bus Citaro. Thus, fuel consumption of the already very efficient conventional Citaro is further reduced, and even more so thanks to electrohydraulic steering, depending on the application and vehicle model. Lower fuel consumption quickly pays off for public transport companies. Society and the environment benefit from lower emissions.
