Fleet as a Marketing Tool: With Funding Knowledge to a Sustainable Fleet through Conversion
Up to 425 km range after an upgrade – without the costs of a new vehicle. In light of rising diesel prices and stricter CO₂ regulations, the electrification of your existing fleet is not only an emission-related decision, but a strategic business one. Using your own fleet as a marketing tool for sustainability through conversion remains possible – however, the funding of up to 80% of the additional costs ran until 2024.
The topic briefly and concisely
Until 2024, the state KsNI funding covered up to 80% of the additional costs of a conversion; since August 2024, no new funding calls are planned.
The retrofitting of existing commercial vehicles (DTE) is more economical than a new purchase due to the continued use of specialized superstructures and lower investment costs.
A retrofitted fleet serves as a powerful marketing tool that makes commitment to sustainability and circular economy visible while reducing operating costs (TCO).
Companies and municipalities are facing a dual challenge: operating costs for diesel fleets are rising inexorably, while legal requirements such as the Clean Vehicles Directive are increasing the pressure to decarbonize. However, many shy away from completely replacing proven utility vehicles, especially when expensive special bodies are involved. The solution lies in the circular economy: a conversion converts your existing vehicles into powerful electric vans. This article shows you in four clear steps how the state funding was recently structured – the federal government's KsNI funding covered up to 80% of the additional costs until 2024, no new funding calls are planned – and how you can still make your fleet future-proof.
Pressure and Opportunity: Regulatory Requirements as a Driving Force
The Clean Vehicles Directive (CVD), implemented through the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), has obligated public contracting authorities since August 2, 2021, to comply with minimum quotas for low-emission vehicles. For the first reference period ending in 2025, for example, 45% of new buses had to be "clean," with half of those even being completely emission-free. These specifications create a clear pressure to act, which has an effect beyond the public sector. Companies that transition early position themselves as pioneers and gain decisive competitive advantages. The transition is not a burden, but a strategic investment that has been supported by funding programs for years. The KsNI funding ran until 2024; no new calls for funding are planned.
Your 4-point action plan for fleet electrification
The path to an electrified fleet is straightforward with the right strategy. Follow these four steps to clearly clarify the funding situation and economic efficiency:
Carry out a funding analysis: Classify the BMDV funding program KsNI, which covered up to 80% of the additional investment costs for vehicle conversion and 40% for the charging infrastructure until 2024. A professional analysis of the total fleet costs is the first step here.
Evaluate vehicle potential: Identify the vehicles in your fleet that are best suited for conversion. Mercedes-Benz Sprinters with expensive bodies in particular offer enormous potential for cost savings.
Calculate Total Cost of Ownership (TCO): Compare the total cost of ownership. A TCO analysis shows that e-vans are the more economical choice thanks to lower energy, maintenance and tax burdens. Studies prove TCO parity with diesel vehicles even today.
Create an implementation roadmap: Plan the concrete steps from commissioning to conversion and integration of the charging infrastructure. A holistic mobility solution ensures a smooth transition.
This structured approach ensures that you know the funding situation and make the technologically and economically best decision for your future.
Costs in Focus: Why Retrofitting Outweighs New Purchases Economically
The decision between conversion and new purchase is a question of economic efficiency and sustainability. The Total Cost of Ownership (TCO), i.e., the total operating costs over a vehicle's lifespan, provides a clear answer here. While purchasing a new electric transporter means high capital commitment, conversion as a sustainable investment protects your liquidity and your existing assets. Particularly for vehicles with special bodies, whose value often exceeds that of the base vehicle, continued use is economically superior. A study by the ICCT proves that electric trucks in Germany have already achieved TCO parity with diesel counterparts, largely driven by subsidies and toll exemptions. Here is a direct comparison of the key factors:
Investment Costs: Conversion is significantly cheaper than a new vehicle; the KsNI subsidy covered up to 80% of the additional costs until 2024.
Preserving Value: Expensive and proven bodies are fully preserved and ready for use.
Operating Costs: Electric drivetrains score with 28-33% lower costs per kilometer due to cheaper electricity and reduced maintenance efforts.
Vehicle Availability: Converting a Sprinter takes only a few weeks, while delivery times for new electric commercial vehicles often amount to many months.
These factors make conversion the faster and more capital-efficient method to modernize the fleet while simultaneously reducing operating costs.
Technology that convinces: Range and charging performance for everyday work.
The practical suitability of electric commercial vehicles is defined by range and charging capacity. Modern DTE solutions offer values here that more than meet the requirements of logistics, trade, and municipal services. The HEERO DTE Sprinter, for example, achieves a range of up to 425 kilometers. For goods transport, the HEERO eTransporter even offers up to 500 kilometers on a single charge. All models use a 110 kWh (gross) battery with 96 kWh of usable capacity, designed for high continuous output. An exception is the medium low-floor bus with a larger 137 kWh battery. The charging performance is equally impressive:
Standard DC fast charging: Up to 135 kW, which means the battery is charged to 80% in around 30 minutes.
Specialized bus solutions: The medium low-floor bus charges at up to 165 kW and is therefore ready for use again even faster.
Flexible charging infrastructure: Setting up own charging points was eligible for funding; in the federal bus program, charging and workshop infrastructure was recently funded at 40%, with the call ending on July 21, 2026.
These technological metrics prove that the electrification of diesel vans requires no compromises in performance, but rather represents genuine technological progress.
Circular economy as a marketing tool: sustainability that pays off
By opting for the conversion, you are sending a strong signal for the circular economy. You avoid the enormous expenditure of resources and energy associated with the production of a completely new vehicle. This not only reduces the carbon footprint of your fleet but also becomes a credible marketing argument. Customers and citizens reward companies that visibly take responsibility and conserve resources. You use your fleet as a marketing tool for sustainability through conversion, thereby communicating innovative strength and emission-related awareness. This strengthens your brand and can provide the decisive advantage in public tenders that take sustainability criteria into account. Deciding on the use of the existing fleet is therefore a clear commitment to circular mobility. In this way, a regulatory necessity becomes a real competitive advantage.
Your next step: Analyze funding potential in three questions.
The KsNI funding ran until 2024; no new calls for funding are planned, and projects that have already been approved will be fully funded. Do not wait until rising toll and CO₂ costs put further pressure on your margins. Take action now to leverage the economic advantages and make your fleet future-proof. Switching to electromobility by converting your proven vehicles is the most direct path to lower operating costs and a positive environmental balance. Start your funding analysis: Answer three questions and receive your subsidy roadmap with the status of the funding programs.
