Municipal driving bans for diesel vehicles and rising operating costs threaten the efficiency of your fleet. Retrofitting your proven diesel vans to electric drive not only protects your investments but also sustainably reduces overall operating costs. Discover the technologically leading solution for municipalities, logistics, and crafts.

The topic briefly and concisely

Retrofitting diesel transporters is an economically attractive alternative to purchasing new ones, in order to prepare fleets for upcoming zero-emission zones.

Due to lower operating and maintenance costs as well as the government subsidies available until 2024, the conversion often pays for itself after just a few years.

The continued use of existing vehicles in the sense of circular economy significantly reduces the CO2 footprint more than the purchase of a new e-transporter.

The introduction of Zero Emission Zones presents fleet operators with a strategic decision: new purchase or conversion? While 35 cities in Europe are already planning to ban combustion engines by 2030, Germany often still lacks a clear legal basis for such zones. Nevertheless, the trend is irreversible. For fleet managers, this means acting now to secure access permits and the operational readiness of their vehicles. HEERO offers a pragmatic and economically superior solution with its patented conversion. We convert your reliable Mercedes-Benz Sprinter to a powerful electric drive, making your fleet fit for a locally emission-free future.

Regulatory Pressure: Why Zero-Emission Zones Are Becoming Relevant for Fleet Operators

Across Europe, hundreds of new low-emission zones are being established to improve air quality in urban centers. Cities like Paris, London, and Amsterdam are planning to introduce complete zero-emission zones by 2030. This development is forcing companies and municipalities to decarbonize their vehicle fleets. Although German legislation is still hesitant, the EU is establishing the basis for stricter local measures with directives such as 2008/50/EC. For fleet operators, this means growing uncertainty regarding access rights for their diesel vehicles. Converting your existing diesel vans for use in zero-emission zones is the proactive response to this challenge. A rapid conversion protects your fleet from impending driving bans. This regulatory dynamic makes holding onto purely diesel fleets an economic risk.

The economically smart alternative: retrofitting instead of buying new

Buying new e-transporters involves high investments and long delivery times. Retrofitting a diesel transporter to electric drive often costs only about half as much as a comparable new vehicle. This is the superior strategy, especially for vehicles with expensive special bodies, as are common in municipalities or crafts. Your proven vehicle base and valuable bodies are fully preserved. The core advantage lies in the continued use of the invested capital. HEERO has perfected this process with the conversion for the Mercedes-Benz Sprinter. We replace the combustion engine with a highly efficient electric drivetrain. Find out how costs compare in detail. This turns the electrification of your fleet not into a burden, but into a strategic advantage.

Technical Excellence: Performance and Range for Everyday Work

Practical suitability determines success in daily use. Our converted HEERO vans offer a range suitable for everyday use of up to 425 km. This performance ensures that your vehicles manage their routes in urban and regional logistics without restrictions. The battery capacity is optimized for the typical application profiles of craft enterprises and municipal service providers. Maintenance costs for an electric drive are also up to 50 % lower than for a diesel. Here are the key performance data of our conversion solution:

  • Range: Up to 425 km (WLTP)

  • Charging time: Fast charging (DC) to 80% in under 90 minutes

  • Engine power: Optimized for high payloads and agile driving behavior

  • Battery life: Designed for over 3,000 charging cycles

  • Payload: Remains almost completely intact thanks to optimized components

These technical facts prove that you do not have to make any compromises when it comes to performance. The analysis of the total cost of ownership shows the full potential. The conversion is therefore not only an ecological decision, but also a technologically advanced one.

Total Cost of Ownership (TCO): How to reduce your fleet costs

Total Cost of Ownership (TCO) is the decisive key figure for any fleet manager. A study by Transport & Environment shows that electric vans are on average 25% cheaper to operate than comparable diesel models. This advantage results from several factors. Energy costs per kilometer are significantly lower; government funding programs covered up to 80% of the conversion costs until 2024. In addition, electric vehicles in Germany were exempt from truck toll charges until the end of 2025, representing significant savings. Amortization of conversion costs is often achieved within 4 to 6 years. With HEERO, you maximize these benefits and reach your sustainability goals faster. Deciding on a conversion is a direct investment in the economic efficiency of your fleet.

Sustainability through circular economy: A double win

Converting your existing fleet is a prime example of a functioning circular economy. Instead of scrapping a fully functional vehicle and producing a new one, we extend its life cycle by many years. This avoids the significant CO2 emissions and resource consumption associated with manufacturing a new van. You not only reduce operating emissions to zero, but also conserve valuable raw materials. This approach significantly reduces your fleet's carbon footprint compared to buying new. Continuing to use the chassis and the body is the most ecologically and economically sensible form of modernization. Using your existing fleet is therefore the best choice for a sustainable future. In this way, your fleet becomes a pioneer for resource-saving logistics.

Customized solutions for municipalities and logistics companies

Every industry has specific requirements for its commercial vehicles. HEERO offers customized conversion solutions for a wide range of use cases. For logistics companies operating in urban areas, the conversion secures access to inner cities and reduces operating costs. For municipalities and their municipal yards, the conversion of special vehicles such as flatbed trucks or sweepers is ideal. The process is clearly defined:

  1. Free initial consultation and analysis of your fleet

  2. Verification of the suitability of your existing vehicles

  3. Planning of the conversion in just 10 working days

  4. Execution of the conversion by our experts

  5. Handover and briefing on the new technology

We understand the needs of fleets with special superstructures and guarantee seamless integration. This is how you can make your municipal fleet future-proof. Conversion is the pragmatic solution to become locally emission-free without long waiting times.
