E-bus conversion subsidy 2025: How to secure 80% subsidy for your fleet

The new funding call from the federal government makes converting your commercial vehicles to electric drives more economical than ever. Act by August 31, 2025.

Increasing operating costs and stricter emissions requirements are putting pressure on your commercial vehicle fleet. The new federal funding 2025 offers a unique opportunity to meet these challenges. Find out how you can not only save up to 80% of additional costs by retrofitting your proven vehicles, but also sustainably reduce your total operating costs.

For fleet operators in municipalities and companies, decarbonizing the vehicle fleet is one of the biggest challenges of the next few years. High investment costs for new electric vehicles and the loss of value of existing special structures represent significant hurdles. With the new funding call from the Federal Ministry of Transport (BMV) to “promote alternative bus drives,” electrification is now becoming tangible.

In particular, promoting e-bus conversion for 2025 opens up a pragmatic and economically superior path. HEERO is positioning itself as your partner here, offering a practical solution with the patented D2E conversion for the Mercedes-Benz Sprinter, which protects investments and reduces operating costs by up to 25%.

Key Takeaways

The federal government is funding the conversion from diesel buses to electric buses in 2025 with up to 80% of the additional costs; the application deadline is August 31, 2025.
The conversion of existing vehicles saves investments in special structures and, thanks to the circular economy, is more sustainable than buying a new one.
Electric vans reduce total operating costs (TCO) by up to 25% per kilometer through lower energy and maintenance costs.

Federal government reactivates funding for e-buses and conversions 2025

In July 2025, the Federal Ministry of Transport launched a new funding call to accelerate the transition to climate-friendly drives. Transport companies and other bus fleet operators can submit project outlines for procurement or conversion by August 31, 2025. Up to 80% of the additional investment costs compared to a diesel vehicle are supported. The program includes battery buses, fuel cell buses and, specifically, the Converting conventional vehicles to electric drives.

Since 2021, around 3,500 buses have already been funded with a volume of 1.2 billion euros. This new call is your opportunity to set the course for an emission-free and economic future. The applications will be approved after the federal budget has been approved in autumn 2025, making the new funding guideline a central pillar for the transport turnaround.

Maintaining value: Why retrofitting outweighs new purchases

The decision to electrify doesn't have to mean the total loss of your previous investments. Many fleets, particularly at municipalities or craft businesses, use expensive special bodies on proven basic vehicles such as the Mercedes-Benz Sprinter. A new purchase would make these valuable structures obsolete. The HEERO D2E-conversion follows the circular economy principle by modernizing the heart of your vehicle — the powertrain — and maintaining the chassis and body.

This approach not only saves your budget by up to 40% compared to buying a new one, but also significantly reduces resource consumption. Remanufacturing is an essential component for reducing dependence on primary raw materials and strengthening resilience. The funding for e-bus conversion for 2025 now makes this route even more attractive. This is how you secure the value of your fleet and make it fit for the next 10 years.

Reduce total operating costs through electrification

The higher purchase costs for electric mobility are more than offset by significantly lower operating costs. A study by Transport & Environment shows that electric vans are already 25% cheaper per kilometer than comparable diesel models. This advantage is due to 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:

E-vehicles are exempt from motor vehicle tax and benefit from toll reductions of up to 50%.

CO2 tax:

The rising CO2 tax on fossil fuels is completely eliminated.

Government funding for e-bus conversion for 2025 massively reduces the initial investment hurdle. With the HEERO conversion, you achieve the TCO advantage without having to bear the costs of a complete new vehicle. An overview of funding rates can be found under E-bus funding.

Application 2025: Funding in 4 steps

The funding application process is competitive and clearly structured. Submissions are made via the federal government's “Easy-online” online portal. To maximize your chances, you should carefully prepare the following steps:

1. Define project: Determine the number of vehicles to be converted and the need for charging infrastructure.

2nd Get a quote: Contact us for a detailed offer for the HEERO D2E upgrade of your Sprinter fleet.

3rd Create a project outline: Describe your project and explain the expected CO2 savings as well as the deployment concept. We will support you in doing so.

4th Submit an application: Submit the complete project outline online by the deadline of August 31, 2025.

Companies that have used few or no e-vehicles to date are given preferential treatment when awarding. Use our funding application checklist to be optimally prepared.

HEERO D2E Conversion: Performance for Practice

Our patented Diesel-to-Electric (D2E) Retrofitting transforms your Mercedes-Benz Sprinter into ultra-modern e-passenger vans. Unlike many standard solutions, our system is designed for maximum performance and durability. With a range of up to 300 km, we set the standard in the industry. The conversion only takes 10 working days and receives the full utility value of your vehicle, including all special structures (such as bus cabins).

Our solution is explicitly included in the current 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 range of consulting services. This is how the e-bus conversion will be supported by 2025 to an immediately implementable and profitable measure.

Conclusion: Set the course for an economical and sustainable fleet now

The current e-bus conversion funding 2025 offers an exceptional opportunity for municipalities and bus companies in regular service or other passenger transport tasks. It makes it possible to switch to electric mobility without having to write off valuable existing vehicles.
