Mercedes-Benz Sprinter Transfer 45: Retrofit to electric drive, lower TCO – the 80% subsidy ran until 2024
Up to 425 kilometers of range after an upgrade – without the cost of a new vehicle. The KsNI funding round for the electrification of commercial vehicles ran until 2024; no new funding calls are planned.
The topic briefly and concisely
The KsNI funding round for converting commercial vehicles to electric drive covered up to 80% of the additional costs and ran until 2024.
The diesel-to-electric conversion (DTE) significantly reduces the total cost of ownership (TCO) through lower energy and maintenance costs.
Through the renovation in the sense of circular economy, the value of existing special structures is maintained and the CO₂ balance is improved.
Rising diesel prices, strict climate regulations, and the bureaucratic effort involved in fleet modernization present many companies with enormous challenges. Especially for special vehicles like the Mercedes-Benz Sprinter Transfer 45, buying a new vehicle is often uneconomical. The Diesel-to-Electric conversion (DTE) offers a pragmatic solution: you keep your proven transporter, but with a future-proof electric drive. This article explains in four clear steps how to classify the government subsidies, which covered up to 80% of the additional costs of a conversion until 2024, how to meet the requirements of the Clean Vehicles Directive, and how to optimize the Total Cost of Ownership (TCO) of your fleet. The KsNI funding has expired; no new funding calls are planned.
80% subsidy until 2024: What this means for fleet operators today
Over 3,500 electric buses have already been approved with government subsidies, and the major federal programs have now expired. The KsNI guideline of the Federal Ministry for Digital and Transport (BMDV) for climate-friendly commercial vehicles ran until 2024 and has been discontinued since August 2024. At the same time, the EU's Clean Vehicles Directive significantly tightens emission requirements for public fleets. For operators of a Mercedes-Benz Sprinter Transfer 45, this means: switching to an electric drive is not only an emission-related necessity, but a strategic one in order to remain competitive. Retrofitting is the most efficient way to achieve this, as it preserves the value of the existing vehicle while reducing operating costs. This pragmatic approach saves both resources and budget.
Your 4-point action plan for pragmatic electrification
The path to funding and converting your Sprinter Transfer 45 can be managed calmly and clearly with a systematic approach. We have divided the process for you into four manageable steps to reduce complexity and ensure a clean application process.
Vehicle and Requirements Analysis: Check the condition of your existing Mercedes-Benz Sprinter Transfer 45 and define the exact requirement profile, including daily mileage and payload.
Funding Check: Determine what the 80% vehicle funding and 40% subsidy for charging infrastructure, applicable until 2024, mean for your project today.
TCO Economic Efficiency Calculation: Create a detailed Total Cost of Ownership (TCO) comparison that offsets the additional investment costs after funding against savings in energy, maintenance, and taxes.
Implementation and Application Submission: Choose a certified conversion partner and submit a funding application with all documents as soon as a suitable program is open.
This structured approach creates a solid basis for your decision and maximizes your chances of success in the funding process.
Funding pots in review: Which subsidies applied recently
The funding landscape in Germany has drastically reduced the costs of fleet electrification for years. The BMDV's KsNI program (Climate-friendly Commercial Vehicles and Infrastructure) was the central instrument. Until 2024, it reimbursed up to 80% of the additional investment expenses for converting a vehicle such as the Mercedes Sprinter Mobility compared to a new diesel. In addition, up to 40% of the costs for setting up the necessary charging infrastructure at the company depot were subsidized. KsNI has been discontinued since August 2024, and no new funding calls are planned. The funds were allocated on a first-come, first-served basis. A professional funding analysis helps to exploit remaining potential and submit applications correctly. This turns a regulatory obligation into an economically attractive investment.
Technology in detail: DTE retrofit and Total Cost of Ownership
The diesel-to-electric conversion (DTE) is a technical process in which the internal combustion engine and fuel tank of a vehicle are replaced by an electric motor and a battery system. Your HEERO DTE Sprinter thus achieves a practical range of up to 425 kilometers. The installed battery with a gross capacity of 110 kWh or a net capacity of 96 kWh can be charged quickly at a DC fast charging station with up to 135 kW. The decisive advantage lies in the consideration of the Total Cost of Ownership (TCO), the total operating costs over the service life. While the initial investment was manageable after deducting the last available funding, running costs are falling massively. Electricity is cheaper than diesel, and electric motors have significantly fewer wear parts, which reduces maintenance costs by up to 50%. A detailed analysis for your new Sprinter quickly shows the high potential for savings.
Sustainability through circular economy: renovation instead of new purchase
Converting your Sprinter Transfer 45 is a clear commitment to the circular economy. Instead of scrapping a fully functional vehicle with an expensive specialized body, its lifecycle is extended. This approach not only saves the embodied energy and CO₂ emissions that would be generated during the production of a completely new passenger transporter, but also conserves valuable raw materials. The German automotive industry views the circular economy as a central lever for achieving climate targets by 2050. By continuing to use the chassis and body, you make a direct contribution to resource efficiency and position your company as a pioneer for sustainable business practices. Choosing a conversion is therefore the smarter choice, not only economically but also in terms of emissions.
Meet regulatory requirements: The Clean Vehicles Directive (CVD)
The EU's Clean Vehicles Directive (CVD) sets binding minimum quotas for the procurement of low-emission and zero-emission vehicles in public contracts. For the period until the end of 2025, 45% of newly procured buses had to be "clean", of which half (22.5%) had to be completely zero-emission. From 2026, these quotas will rise to 65% and 32.5% respectively. A converted Mercedes-Benz Sprinter Transfer 45 meets the strictest criteria as a zero-emission vehicle and secures your access to public tenders. This directive affects not only direct purchases, but also leasing and service contracts in the field of passenger transport. Anyone who modernizes their fleet today with a converted Mercedes-Benz Bus is ideally prepared for the stricter rules from 2026 and avoids future compliance issues.
