Up to 425 km of range after a diesel-to-electric upgrade – without the cost of a new vehicle. The current funding round from the federal government makes the electrification of your Mercedes VIP bus more economical than ever, but the application deadline is August 31, 2025.

The topic briefly and concisely

The application deadline for the 80% funding for e-buses and conversions by the BMDV ends on August 31, 2025.

Retrofitting an existing Mercedes VIP bus (DTE) is often more economical than purchasing a new one, as it preserves the value of the conversion and reduces the Total Cost of Ownership (TCO).

Thanks to ranges of up to 400 km and DC fast charging of up to 165 kW, electric VIP buses are fully practical for demanding passenger transport.

Rising diesel prices, complex bureaucracy, and strict climate regulations such as the Clean Vehicles Directive (CVD) are putting pressure on fleet operators. Purchasing a Mercedes VIP bus or modernizing an existing fleet requires a strategic decision. Electrification is the answer, but the investment must pay off. Instead of acquiring expensive new vehicles, diesel-to-electric conversion (DTE) offers a pragmatic solution. It not only secures your investment in high-quality vehicle bodies but also significantly reduces the total cost of ownership (TCO). With the current funding guidelines from the BMDV covering up to 80% of the conversion costs, now is the ideal time to make the switch.

Deadlines and facts: The dual urgency of bus electrification

The time for the electrification of your bus fleet is pressing for two reasons: legal requirements and a limited-time funding opportunity. The deadline for submitting project outlines for the current funding round of the Federal Ministry for Digital and Transport (BMDV) ends on August 31, 2025. At the same time, the Clean Vehicles Directive (CVD) continuously tightens the procurement rules for public authorities.

These facts highlight the current situation for fleet operators:

  • 80% funding rate: The BMDV subsidizes the additional costs for the acquisition of electric buses as well as the conversion of diesel vehicles by up to 80%.

  • 40% for infrastructure: The necessary charging infrastructure is also subsidized by up to 40% of the investment costs.

  • CVD quotas: By the end of 2025, 45% of the buses in public procurement must be

Your 4-step plan for a funded e-bus fleet

The path to the electrified VIP bus is uncomplicated with the right strategy. We have divided the process for you into four clear steps to ensure compliance with the deadline of August 31, 2025.

  1. Needs analysis and fleet check: Analyze your current routes, daily mileage, and vehicle requirements. This creates the data foundation for selecting the appropriate e-solution with a range of up to 400 km for our tourer.

  2. Define solution concept: Decide between a new vehicle and a Diesel-to-Electric conversion (DTE). Especially with a high-quality Mercedes VIP bus, the DTE conversion protects your investment in the upgrade. Learn more about our conversion solutions.

  3. Apply for funding: Submit your application on time to the project sponsor Jülich (PtJ) with our support. We help you correctly present CO₂ reduction and funding needs to maximize the chances for the 80% funding.

  4. Implementation and integration: After funding approval, the conversion or delivery of your new e-bus takes place. In parallel, we plan and install the appropriate charging infrastructure with up to 165 kW DC charging power.

This structured approach ensures that you take full advantage of the current funding period and future-proof your fleet.

Economic efficiency in detail: TCO, subsidies, and technology

Targeted use of funding pots

The "Guideline for the Promotion of Alternative Drives for Buses in Public Transport" is the central instrument to reduce investment costs. Since 2021, around 3,500 e-buses have already been approved, saving 2.8 million tonnes of CO₂ over their lifetime. The funding covers 80% of the additional investment costs compared to a diesel bus and explicitly also applies to DTE conversions. This makes the conversion of an existing Mercedes-Benz bus particularly attractive.

Total Cost of Ownership: The true cost advantage

The acquisition costs are only part of the equation. The Total Cost of Ownership (TCO) shows the true savings potential. Studies show that the TCO of an e-bus can be up to 10% lower than that of a diesel bus. The reasons for this are varied:

  • Lower energy costs: Electricity is cheaper to operate and more price-stable than diesel.

  • Reduced maintenance: Savings of up to 40% on maintenance are possible as oil changes or exhaust system repairs are not required.

  • Value retention: A DTE conversion preserves the value of your expensive VIP conversion, which would be lost with a new purchase.

A detailed Total Cost of Ownership comparison is the key to an informed decision.

Charging infrastructure and range for everyday use

The practicality of an e-bus depends on range and charging performance. Our solutions are designed for professional use. The Heero Tourer on a Sprinter basis offers a real range of up to 400 km with its 96 kWh net battery. Thanks to a DC fast charging capacity of up to 135 kW, the battery can be recharged to 80% in about 40 minutes. Even our larger buses achieve ranges of up to 300 km and charging capacities of 165 kW, which significantly simplifies deployment planning.

Sustainability as a strategy: Circular economy in the fleet

If you purchase and convert a luxury bus, you are not only investing in emissions-free transport but also in the circular economy. Instead of scrapping a fully functional vehicle with high-quality interiors, its lifecycle is extended. This approach significantly reduces resource consumption and the CO₂ emissions associated with producing a new vehicle.

Converting an existing Mercedes VIP bus is a clear commitment to sustainable business practices. You conserve valuable resources and position your company as a responsible player. Reducing waste and efficiently reusing existing materials are central advantages of the circular economy, which also positively impacts your company's image. With a converted vehicle, you send a strong signal for ecological and economic reason. Secure your free e-bus funding now and become part of the movement.

FAQ

Why is retrofitting an existing bus often more sensible than buying a new one?

For a Mercedes VIP bus, the individual and expensive interior design represents a significant value. A diesel-to-electric retrofit preserves this value, while it would be lost with a new purchase. Additionally, retrofitting is more resource-efficient and is eligible for up to 80% funding, which significantly reduces the total investment.



What does Total Cost of Ownership (TCO) mean for an E-bus?

TCO refers to the total operating costs over the entire lifespan of a vehicle. For E-buses, the acquisition costs are higher, but the ongoing costs for energy (electricity instead of diesel) and maintenance (up to 40% cheaper) are significantly lower. This leads to better long-term profitability.



Who is eligible to apply for BMDV funding?

Transportation companies and other users from the bus industry, including operators of long-distance, charter, or company transport, are eligible to apply for the BMDV's E-bus funding. The application deadline for the current funding round ends on August 31, 2025.



How long does it take to fast-charge an electric VIP bus?

The charging time depends on the battery size and the charging power. A Heero Tourer (96 kWh net capacity) charges at a DC fast-charging station with 135 kW in about 40 minutes from 10% to 80%. Our medium low-floor buses with 115 kWh net capacity charge with up to 165 kW.



What is the difference between gross and net battery capacity?

The gross capacity is the total physically installed storage amount of the battery. The net capacity is the actually usable portion. A buffer between gross and net protects the battery, slows down aging, and ensures a long lifespan and consistent range.



Do I have to plan the charging infrastructure myself?

No, Heero offers a comprehensive solution. We not only advise you on vehicle selection and funding but also plan and implement the charging infrastructure suitable for your fleet, which is also eligible for up to 40% funding.
