E-Bus conversion funding: What 70% grant on additional costs covered for your fleet
Rising operating costs and stricter emission regulations are putting your fleet under pressure. The federal funding for converting diesel to electric buses covered up to 70% of the additional costs; the funding call ended on July 21, 2026. Learn how you can sustainably reduce total cost of ownership by converting your proven vehicles.
The topic briefly and concisely
The federal government funded the conversion from diesel to electric buses with up to 70% of the additional costs; the application deadline ended on July 21, 2026.
Retrofitting existing vehicles protects investments in special bodies and is more sustainable than purchasing a new one thanks to the circular economy.
Electric vans reduce total operating costs (TCO) by up to 25% per kilometer through lower energy and maintenance costs.
For fleet operators in municipalities and companies, the decarbonization of the vehicle fleet is one of the greatest challenges of the coming years. High investment costs for new electric vehicles and the loss of value of existing special bodies present significant hurdles. With the funding call from the Federal Ministry of Transport (BMV) for the "promotion of alternative drives for buses," electrification became tangible; the call ended on July 21, 2026. Especially the funding of e-bus conversion for 2025 opened up a pragmatic and economically superior path. HEERO positions itself here as your partner, offering a practical solution with the patented conversion for the Mercedes-Benz Sprinter that protects investments and reduces operating costs by up to 25%.
Federal government reactivated funding for e-buses and conversions in 2025
The Federal Ministry of Transport has accelerated the transition to climate-friendly drives through several funding calls; the most recent ran from May 26 to July 21, 2026. During this period, transport companies and other operators of bus fleets could submit project outlines for acquisition or retrofitting. Up to 70% of the additional investment costs were funded for low levels of electrification, otherwise 55%, compared to a diesel vehicle. The program covers battery buses, fuel cell buses, and explicitly the retrofitting of conventional vehicles to electric drive. Since 2021, around 3,500 buses have already been funded with a volume of 1.2 billion euros. The call was the starting point for many operators into a locally emission-free and economical fleet. The approval of the applications took place after the adoption of the respective federal budget. This made the new funding directive a central pillar for the transport transition; a subsequent call has not been announced.
Value retention: Why retrofitting surpasses new purchases
The decision to electrify does not have to mean the total loss of your previous investments. Many fleets, especially in municipalities or craft businesses, use expensive custom bodies on proven base vehicles such as the Mercedes-Benz Sprinter. A new purchase would make these valuable bodies obsolete. The HEERO conversion follows the principle of the circular economy by modernising the heart of your vehicle – the powertrain – and preserving the chassis and body. This approach not only protects your budget by up to 40% compared to a new purchase, but also significantly reduces resource consumption. Remanufacturing is an essential component in reducing dependence on primary raw materials and strengthening resilience. Funding for the e-bus conversion for 2025 had additionally supported this path; the most recent call ended on 21 July 2026. This is how you secure the value of your fleet and make it fit for the next 10 years. Find out more about the advantages in our detailed solution comparison.
Reduce total operating costs through electrification
The higher acquisition costs for electromobility are more than compensated for by significantly lower operating costs. A study by Transport & Environment proves that electric vans are already 25% cheaper per kilometer today than comparable diesel models. This advantage results from several factors:
Energy costs: Electricity costs per kilometer are up to 70% lower than those for diesel.
Maintenance: Electric drives have fewer wear parts, which reduces maintenance costs by over 60%.
Taxes & tolls: Electric vehicles are exempt from vehicle tax and benefit from toll reductions of up to 50%.
CO2 tax: The rising CO2 tax on fossil fuels is completely eliminated.
The state funding for electric bus conversion for 2025 massively reduced the initial investment barrier; the funding call ended on July 21, 2026. With the HEERO conversion, you achieve the TCO advantage without having to bear the costs of a completely new vehicle. An overview of the funding rates can be found under Förderung von E-Bussen.
Application Process 2025: This was the path to funding
The application process for the funding was competitive and clearly structured. Submissions were made via the federal government's "easy-Online" portal. To maximize your chances, you should carefully prepare the following steps:
Define project: Determine the number of vehicles to be converted and the demand for charging infrastructure.
Obtain a quote: Contact us for a detailed quote for the HEERO conversion of your Sprinter fleet.
Create a project sketch: Describe your project and outline the expected CO₂ savings as well as the deployment concept. We will support you with this.
Submit application: The complete project sketch had to be submitted online by the deadline; the call for funding ended on July 21, 2026.
Companies that previously had few or no electric vehicles in use were given priority in the allocation process. Use our Checkliste für den Förderantrag to be optimally prepared.
HEERO D2E Conversion: Performance for Practice
Our patented conversion transforms your Mercedes-Benz Sprinters into state-of-the-art electric vans. Unlike many standard solutions, our system is designed for maximum performance and durability. With a range of up to 425 km, we set the benchmark in the industry. The conversion takes only 10 working days and preserves the full utility of your vehicle, including all special bodies. Our solution was explicitly included in the federal funding call. This allows you to combine the proven quality of your fleet with pioneering drive technology. The necessary planning of the charging infrastructure is also part of our comprehensive consulting service. This ensures that electric bus conversion remains an economically viable and profitable measure even after the 2025 funding period.
Conclusion: Now set the course for an economical and sustainable fleet.
The electric bus conversion subsidy 2025 was an extraordinary opportunity for logistics companies, municipalities, and craft businesses. It enabled the transition to electromobility without having to write off valuable existing vehicles. The combination of a subsidy of recently up to 70% of the additional costs, reduced operating costs, and the preservation of your fleet's value continues to make the HEERO conversion a viable decision. You not only meet future environmental regulations but also increase your competitiveness. As an innovative partner, we accompany you from the analysis through subsidies consulting to the final implementation. Cost pressure is rising regardless of the funding situation. The funding call 2026 for buses ended on July 21, 2026; nevertheless, actively shape the future of your fleet. Request your personal consultation or book an everyday test free of charge.
