Midibus manufacturers: Why upgrading your fleet is now the better investment
Around 3,500 electric buses have already received funding – when will you electrify your fleet? Rising diesel prices and strict EU regulations require pragmatic action; the funding deadline for buses ended on July 21, 2026, with up to 70% of the additional costs being subsidized.

The topic briefly and concisely
The deadline for applying for funding to retrofit midibuses to electric drive ended on July 21, 2026; up to 70% of the additional costs were funded.
The diesel-to-electric conversion is often more economical than purchasing a new electric bus due to lower investment and operating costs (TCO).
The Clean Vehicles Directive (CVD) establishes binding quotas for clean vehicles and increases the pressure on fleet operators.
The search for a suitable midibus manufacturer is a major challenge for many public transport operators and municipalities. They are faced with the task of decarbonizing their fleet in accordance with the Clean Vehicles Directive (CVD), but struggle with high investment costs and long delivery times for new vehicles. However, there is an economically and environmentally superior alternative: the diesel-to-electric conversion of your proven existing vehicles. This approach not only protects your budget, but also secures the value of your special bodies and significantly accelerates the transition to a locally emission-free fleet. The bus funding guideline of the Federal Ministry for Digital and Transport (BMDV) has additionally made this step attractive for years.
Legal pressure meets economic hurdles
The Clean Vehicles Directive, implemented in Germany through the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), forces public authorities to act. By the end of 2025, 45 percent of newly procured buses had to be low-emission, with half of them even completely emission-free. From 2026, these quotas will rise to 65 percent. These requirements present many fleet managers with enormous financial hurdles, as the acquisition costs for new electric midibuses significantly exceed those for diesel vehicles. In addition, there are often long delivery times from manufacturers, which further complicates a timely transition. Many operators overlook the fact that retrofitting represents a fast and legally compliant solution. This strategic pressure requires a solution that goes beyond purely purchasing new vehicles.
The smart alternative: retrofit midibuses instead of replacing them
Instead of investing in expensive new vehicles, conversion offers a pragmatic solution. In this process, the combustion engine is removed from your existing midibus and replaced with a modern electric drivetrain. The biggest advantage is that the proven vehicle chassis and expensive custom bodies are preserved. This is not only significantly cheaper than a new purchase, but also promotes the circular economy and reduces the CO₂ footprint by up to 70%. Here are the key advantages at a glance:
Cost savings: The conversion costs are significantly lower than the price of a new electric midibus.
Sustainability: You extend the service life of your vehicles and conserve valuable resources.
Value preservation: Your investments in custom bodies, such as those for passenger transport with special requirements, remain completely preserved.
Fast availability: The conversion of a vehicle takes only a few weeks, not months or years.
Lower operating costs: Benefit from up to 50% lower operating costs and up to 40% lower maintenance costs compared to diesel.
With efficient conversion solutions, you make your fleet future-proof. This approach is not only a technical decision, but above all a strategic one for greater cost-effectiveness.

The funding situation for midibuses has changed. With a clear strategy, you can classify the remaining options. Here is your checklist for a successful transition:
Conduct a fleet analysis: Identify the midibuses in your fleet that are ideally suited for a DTE conversion. Sprinter-based models are often excellent candidates.
Check funding opportunities: Applications under the BMDV bus directive were possible during the call from May 26 to July 21, 2026. Up to 70% of the additional costs of vehicle conversion were subsidized for a low level of electrification, otherwise 55%, and 40% for the necessary charging infrastructure.
Calculate Total Cost of Ownership (TCO): Have a detailed TCO analysis prepared. This compares the total costs of conversion versus buying new over the entire lifespan and proves the economic efficiency of the conversion.
Plan implementation and charging infrastructure: Define the schedule for the conversion and the installation of the charging infrastructure to ensure a smooth transition without operational disruptions.
A structured plan is the key to realistically assessing the e-bus funding for 2025. The analysis of the total costs often shows a surprisingly clear picture.
Funding pots and TCO: The economics in detail
The financial attractiveness of the electric conversion is based on two pillars: government subsidies and long-term operating cost savings. The bus funding program of the BMDV was a decisive lever for drastically reducing investment costs. It recently subsidized the additional costs of an alternative drive compared to a diesel reference vehicle by up to 70%, otherwise 55%. However, the true strength of the conversion is demonstrated in the Total Cost of Ownership (TCO). While a new electric bus incurs high acquisition costs, the conversion is significantly more cost-effective and massively reduces running costs. Electricity is cheaper and more stable than diesel, and the maintenance effort for an electric drive is up to 40% lower, as components such as the exhaust system or oil changes are eliminated. These savings make the conversion the most economical choice over the vehicle's service life. The technology behind it has long been suitable for everyday use and proven in practice.
Technology that convinces: Range and charging power for everyday life
Modern conversion solutions offer performance values that more than meet the requirements of scheduled and shuttle services. Instead of worrying about range, you receive a solution tailored to your operational profile. Our electric bus models are based on proven technology and deliver reliable performance. Here is an overview of the key figures:
HEERO low-entry bus: With a gross battery capacity of 137 kWh, it achieves a range of up to 300 km and charges at up to 165 kW.
HEERO low-floor rear bus: With its 110 kWh battery, it also manages up to 300 km and charges at up to 135 kW.
HEERO Tourer (minibus for 9 people): This model even offers a range of up to 400 km with a battery capacity of 110 kWh.
These ranges easily cover most daily routes in urban and regional transport. Thanks to high DC charging capacities, the vehicles are also quickly ready for use again, which maximizes operational flexibility. As a result, technology is no longer an obstacle, but the trailblazer for your electric future.
Conclusion: What the funding situation means for your fleet planning
Searching for a new midibus manufacturer is not the only way to achieve electrification. The retrofit of your existing fleet is a faster, more sustainable, and, above all, more economical alternative. By doing so, you not only comply with the legal requirements of the Clean Vehicles Directive but also sustainably reduce your operating costs. The 2026 funding call for buses ended on July 21, 2026; most recently, up to 70% of the additional costs were subsidized. Nevertheless, do not wait until rising operating costs and regulatory pressure limit your options.
