Buy a 20-seat minibus: Classifying the funding after the 2026 call for proposals
Over 3,500 e-buses have already benefited from government subsidies. The deadline for this funding has expired – we will clarify on a case-by-case basis which programs are currently open.
The topic briefly and concisely
The federal bus subsidy covered up to 70% of the additional costs for electric vehicles and conversions; the call for funding ended on July 21, 2026.
Converting an existing diesel minibus (DTE) is often more economical than buying a new one, as expensive components are retained and the total cost of ownership decreases.
The Clean Vehicles Directive requires public authorities to meet fixed quotas for zero-emission buses (45% by 2025), making electrification mandatory.
The decision to purchase a 20-seat minibus is a significant investment for municipalities and businesses. Rising diesel prices, strict climate targets from the Clean Vehicles Directive, and growing pressure to reduce the total cost of ownership (TCO) make choosing the right vehicle complex. Instead of making an expensive new purchase, converting existing vehicles offers a pragmatic and highly economical solution. This article shows you how to reduce costs, meet statutory requirements, and correctly assess the funding situation by electrifying your existing fleet: The KsNI guideline ran until 2024, and the call for bus funding applications ended on July 21, 2026.
The pressure to act: Why time is running out for fleet operators by 2025
The operation of passenger and commercial vehicle fleets faces three central challenges: rising operating costs, stricter environmental regulations, and a changed situation regarding government subsidies. The KsNI directive of the Federal Ministry for Digital and Transport (BMDV) ran until 2024; the federal bus funding call ended on July 21, 2026. At the same time, the Clean Vehicles Directive (CVD), implemented through the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), obliges public contracting authorities to meet fixed quotas for emission-free vehicles. For buses, this quota in the first reference period until the end of 2025 was 45%, of which half had to be completely emission-free. This combination of expired funding and rising regulatory pressure requires a strategic decision. Those who hesitate risk failing to meet legal requirements; which programs are currently open, we clarify on a case-by-case basis. The question is therefore no longer whether, but how electrification can be achieved most economically.
Your 4-point action plan for economic electrification
A strategic transition secures maximum benefits for you. With this checklist, you can safely navigate through the process:
Conduct a needs analysis: Define the exact requirements for range, seats, and payload. A converted Mercedes-Benz Sprinter can often be more flexible and cost-effective than purchasing a rigid new 20-seater.
Evaluate the existing fleet: Assess the potential of your existing diesel vehicles. A conversion protects your investment in expensive bodies and is particularly sustainable thanks to the circular economy.
Check funding opportunities: The BMDV directive subsidized the conversion and the charging infrastructure; its application deadline has expired. We will clarify on a case-by-case basis which programs are currently open.
Calculate Total Cost of Ownership (TCO): Compare the TCO of a new vehicle with that of a conversion solution. Consider the lower energy, maintenance, and tax costs of an electric vehicle, which often offset the higher acquisition costs after just three years.
This plan forms the basis for a well-founded decision that combines economy and ecology.
Classifying funding pots: What covered up to 70% subsidy
The funding landscape in Germany provided a strong argument for electrification for years. Through the KsNI directive of the BMDV, companies and municipalities could receive reimbursement for up to 80% of the additional investment costs for an electric vehicle or a retrofit. In parallel, the necessary charging infrastructure was eligible for funding. The decisive factor is the program status: The KsNI directive has been discontinued since August 2024. New funding calls are not planned; projects that have already been approved will be fully funded. A HEERO Sprinter with up to 425 km range fell entirely under this funding. For the E-bus purchase, the most recent bus call ran from May 26 to July 21, 2026. We clarify which programs are currently open on a case-by-case basis.
Cost comparison: Why retrofitting often outperforms buying new
The Total Cost of Ownership (TCO) is the decisive key figure for fleet managers. It includes all costs over the entire lifespan of a vehicle, not just the purchase price. Studies show that electric vehicles have clear advantages here. While the acquisition can be more expensive, the ongoing costs for energy, maintenance, and taxes are significantly lower. A DTE conversion reinforces this effect. It preserves the value of your existing vehicle and its often expensive special bodies. The TCO analysis shows that a converted vehicle is often cheaper than a new diesel minibus after just a few years. The CO₂ savings also lead to advantages with the GHG quota. With our Bus Configurator, you can compare different options and find the most economical solution for your needs.
Technology in detail: Range and performance for practical use
Modern electric drives are designed for the demanding daily routine in passenger transport. HEERO relies on field-tested technology to ensure maximum reliability. Here are the facts:
Range: A Sprinter converted with the HEERO system achieves a realistic range of up to 425 km. Our minibus Tourer for 9 passengers manages up to 400 km.
Battery: We install a powerful battery with 110 kWh gross or 96 kWh net capacity, optimized for durability and performance.
Charging capacity: With a DC fast charging capacity of up to 135 kW, the battery is recharged to 80% in around 30 minutes, which minimizes downtime.
Diesel-to-Electric (DTE): In this process, we replace the diesel engine and the drivetrain with a highly efficient electric drive. The vehicle body remains untouched, which represents a huge cost advantage, especially for special vehicles.
These technological key figures prove that deciding against a new 20-seater and in favor of a flexible conversion solution does not mean compromising on performance.
Sustainability through circular economy: Rebuild instead of throw away
The decision to opt for a DTE conversion is an active contribution to the circular economy. Instead of scrapping a fully functional vehicle and producing a new one, the lifecycle of the existing vehicle is extended. This significantly reduces the need for raw materials such as steel, aluminum, and plastic. The CO₂ emissions that would occur during the manufacture of a completely new vehicle are entirely avoided. This approach not only protects the environment but also your budget. Reusing the chassis and the body is the purest form of resource efficiency and makes the electrification of your fleet a showcase project for active sustainability. Such a passenger transport vehicle stands for a future-oriented mobility strategy.
