Electrifying Mercedes commercial vehicles: Secure 80% funding before the deadline on August 31, 2025.
Up to 425 km range after a diesel-to-electric upgrade – without the cost of a new vehicle. The time for electrifying your Mercedes commercial vehicles is running out, as the current funding round ends on August 31, 2025.
The topic briefly and concisely
The application deadline for the 80% funding for the electrification of commercial vehicles ends on August 31, 2025.
The retrofitting (DTE) of existing Mercedes commercial vehicles is often more economical than buying new due to lower TCO and the preservation of the value of special bodies.
HEERO conversions offer practical ranges of up to 425 km while maintaining the full functionality of the base vehicles.
Rising diesel prices, high bureaucratic effort, and strict climate regulations such as the Clean Vehicles Directive (CVD) are putting pressure on fleet operators. Many are wondering how they can future-proof their specialized and expensive Mercedes commercial vehicles without having to invest in completely new vehicles. The solution lies in retrofitting. With a Diesel-to-Electric (DTE) retrofit, you can continue to use your tried-and-true vehicles, meet all regulatory requirements, and benefit from a government funding of 80 percent on the conversion costs. Act now, as the application deadline for this attractive funding ends on August 31, 2025.
First 2025: Why now is the crucial moment for your fleet
The pressure to decarbonize vehicle fleets is steadily increasing. The EU Clean Vehicles Directive, implemented in Germany through the Clean Vehicles Procurement Act, already specifies clear quotas for low-emission vehicles in public contracts. By the end of 2025, for example, 38.5 percent of the purchased light commercial vehicles must be considered 'clean.' Starting in 2026, these requirements will become even stricter. At the same time, the current funding period of the Federal Ministry for Digital and Transport (BMDV) is coming to an end. Applications for funding of 80 percent of the additional costs for electrification must be submitted by August 31, 2025. This deadline makes quick but considered action essential for every fleet manager. Hesitation can mean losing subsidies amounting to several tens of thousands of euros per vehicle. The combination of regulatory pressure and expiring subsidies creates a narrow window of time that must be strategically utilized.
Your four-point plan for utilizing the 80% funding
The path to subsidized electrification of your Mercedes commercial vehicles is pragmatic and clearly structured. Use this checklist to navigate safely through the process:
Fleet analysis: Identify the Mercedes-Benz Sprinter in your fleet whose bodies are expensive and whose purpose is critical. This is exactly where a conversion unfolds its full potential, as the vehicle value is preserved.
Check profitability: Calculate the Total Cost of Ownership (TCO). The TCO, or total operating costs, include energy, maintenance, taxes, and insurance, in addition to the purchase. A conversion often significantly reduces the TCO compared to diesel after just four to six years.
Apply for funding: Submit the application under the KsNI guidelines by 31 August 2025. The funding covers 80 percent of the additional investment costs for the Diesel-to-Electric (DTE) conversion and 40 percent for the necessary charging infrastructure.
Select implementation partner: Work with a certified specialist like Heero. We guarantee a professional conversion of your Sprinter to electric and support you throughout the entire process.
This structured approach not only ensures you the maximum funding but also makes the transition plannable and economically advantageous.
Secure the TCO advantage: This is how retrofitting surpasses buying new
The decision between converting an existing Mercedes commercial vehicle and purchasing a new E-transporter is primarily an economic one. While the acquisition costs for new electric vehicles are high, the conversion focuses on reducing total cost of ownership (TCO). A Heero DTE-Sprinter with up to 425 kilometers of range is a clear example. The additional investment costs for the conversion are subsidized by 80 percent through the KsNI directive. As a result, the costs are amortized much faster due to lower energy and maintenance expenses. An electric motor has fewer wearing parts than a diesel engine, which reduces service costs by up to 50 percent. Additionally, electricity costs per kilometer are more stable and generally lower than those for diesel. For municipalities and craft businesses with expensive specialized equipment, this is the logical choice to protect investments and sustainably optimize your total operating costs. The conversion is thus not only a contribution to sustainability, but also a strategic investment in the future viability of your fleet.
Performance and range: HEERO technology for your Mercedes fleet
The practicality determines the success of electrification. Heero relies on tried-and-tested Mercedes-Benz quality for all conversions, combined with powerful e-technology. Here are the facts:
High ranges: Our converted Sprinter (DTE) reaches up to 425 kilometers. The Heero eTransporter even achieves up to 500 kilometers, while our bus solutions cover up to 300 kilometers.
Efficient batteries: We standardly install a battery with 110 kWh gross and 96 kWh net capacity. The mid-low-floor bus is equipped with a larger battery with 137 kWh gross for demanding routes.
Fast charging: With up to 135 kW DC charging power (standard), the vehicles are quickly ready for use again. Our mid-low-floor bus even charges with up to 165 kW, allowing an 80 percent charge in about 30 minutes.
Full functionality: All vehicle functions and compatibility with existing structures remain fully intact after conversion.
These performance data demonstrate that certified conversion solutions require no compromises in usability. They offer a reliable basis for logistics companies, municipalities, and craft businesses.
Circular Economy in Practice: The DTE Transformation Process
The conversion of a Mercedes commercial vehicle is a prime example of practical circular economy. Instead of scrapping a functioning vehicle with a valuable build, its lifecycle is extended by many years. This process not only saves your budget but also conserves valuable resources and saves a significant amount of CO₂ that would be emitted during the production of a new vehicle. The conversion process is highly efficient and typically takes only ten to twelve working days. You receive your familiar vehicle back – only quieter, cleaner, and significantly cheaper to maintain. This approach is particularly the most economically and ecologically sensible solution for fleets with custom Sprinter builds. Thus, a solid diesel transporter transforms into a modern electric commercial vehicle, well-equipped for the coming years. This closes the loop from economic necessity to ecological responsibility.
