Retrofit municipal utility vehicles to zero emissions: Economical and future-proof
Rising cost pressure and stricter environmental regulations are forcing municipal fleets to take action. Converting existing diesel vehicles to a high-performance electric drive is a pragmatic solution. It not only ensures compliance with regulations but also conserves budgets and valuable resources.
The topic briefly and concisely
The conversion of existing municipal commercial vehicles protects investments in expensive specialized equipment and avoids their premature depreciation.
Thanks to the subsidy programs available until 2024 and lower operating and maintenance costs, the total cost of ownership (TCO) of a converted vehicle fell by up to 40% compared to diesel.
The HEERO D2E retrofit ensures compliance with the Clean Vehicles Directive and access to future zero-emission zones in city centers.
Cities and municipalities in Germany are facing a double challenge: The EU's Clean Vehicles Directive prescribes binding quotas for emission-free new acquisitions, while at the same time more and more city centers are establishing zero-emission zones. For municipal fleets, which often rely on expensive specialized vehicles, this means enormous investment pressure. Purchasing a completely new electric vehicle is not only costly, but also leads to the premature depreciation of valuable bodies. With its patented conversion, HEERO offers a technologically leading and economically superior alternative to make municipal commercial vehicles fit for the transition to zero emissions in order to comply with urban regulations.
Act in compliance with the law: The Clean Vehicles Directive as a driver
Key Takeaways
Investment Protection: The conversion preserves expensive special superstructures and prevents premature depreciation of up to 80% of the vehicle's value.
Cost-Effectiveness: Through the conversion, total cost of ownership (TCO) can be reduced by up to 40% compared to diesel.
Future-Proofing: Converted vehicles meet the criteria for zero-emission zones and the EU's Clean Vehicles Directive.
Sustainability: The principle of the circular economy avoids the CO2 emissions generated during the production of a new vehicle.
The EU Clean Vehicles Directive, implemented in Germany through the Clean Vehicles Procurement Act (SaubFahrzeugBeschG), is no paper tiger. Since August 2021, it has obliged public contracting authorities to comply with binding minimum quotas for low-emission and zero-emission vehicles during procurement. For light commercial vehicles, the quota stands at 38.5%, of which a large portion must be completely emission-free starting in 2026.
This regulation directly affects the core of municipal services, from waste disposal to the maintenance of green spaces. Cities like Hamburg and Stuttgart are already planning driving bans that will severely restrict the use of diesel vehicles in urban areas. The transition is therefore no longer an option, but a necessity to secure public services of general interest in the future. The challenge lies in carrying out this transformation without blowing the municipal budgets.
The dilemma with special setups: buying new is often not a solution.
A typical municipal vehicle, such as a sweeper or a flatbed truck with a crane based on a Sprinter, has a service life of 10 to 15 years. The expensive specialized body often accounts for more than 50% of the total value. Purchasing a new electric equivalent would mean scrapping this fully functional and valuable technology prematurely.
This destruction of capital makes no economic or ecological sense. The investment in a new electric van with a specialized body can quickly exceed €150,000, while the existing body could still be used for many years. This is precisely where strategic retrofitting comes in, building a bridge between regulatory pressure and economic common sense.
The HEERO D2E conversion: Protect investments and increase performance
Instead of decommissioning a proven vehicle, HEERO replaces the diesel drivetrain with a state-of-the-art, electric system. This process, known as retrofitting, is the core competence of HEERO and is based on the principle of the circular economy. The entire conversion process is designed for maximum efficiency and quality.
The process is clearly defined and takes only about 10 working days:
Analysis of the base vehicle and the requirement profile.
Removal of the complete diesel drivetrain including the tank and exhaust system.
Installation of the pre-assembled HEERO electric drive system with motor, battery, and power electronics.
Integration into the existing vehicle electronics of the Mercedes-Benz Sprinter.
Comprehensive quality control and test drives before handover.
The result is a vehicle that not only complies with regulations for the next 10 to 15 years but also maintains or even exceeds its original performance. This ensures future-proofing for low-emission zones without having to tie up new capital.
Technical data that convinces: Focus on range and payload
Concerns about electric commercial vehicles often relate to range and practical suitability. The HEERO technology refutes these reservations with impressive performance data, specially tailored to the requirements of municipalities, logistics, and trade. A converted Sprinter offers a practical solution for everyday use without compromise.
The technical specifications speak for themselves:
Range: Up to 425 km according to WLTP City, which by far exceeds the typical daily distances in municipal operations of 80-120 km.
Performance: A peak power of 150 kW ensures dynamic starting and sovereign power reserves.
Payload: The payload remains almost identical to the original diesel vehicle, so that there are no restrictions on loading.
Charging time: At a DC fast charging station, the battery is charged from 20% to 80% in only about 60 minutes.
These values prove that the conversion of municipal commercial vehicles to zero emissions is not just a regulatory obligation, but represents a technological upgrade. A practical example from Bergisch Gladbach shows the successful implementation in the daily routine of waste management.
TCO analysis: How retrofitting can reduce operating costs by up to 40%
The decision in favor of conversion is primarily an economic one. A total cost of ownership (TCO) calculation shows that the HEERO solution is superior to a new diesel or electric vehicle. The savings result from several factors that add up over the years.
Lower operating costs are a key advantage. The energy costs per 100 km for an electric drive are significantly lower than diesel costs. In addition, expensive maintenance items such as oil changes, exhaust system repairs, or the replacement of wear parts on the combustion engine are eliminated. A savings of around 50 percent in maintenance costs is realistic.
In addition, municipalities benefited from subsidy programs that explicitly supported the conversion of commercial vehicles and could cover up to 80% of the additional costs until 2024. In combination with the vehicle tax exemption for electric vehicles, the investment in the conversion amortizes significantly faster than a new purchase. Using existing fleet assets is therefore the smartest choice.
Conclusion: Your advantage with HEERO – Partnership for a clean and economical future
Converting municipal fleets to locally emission-free drives is inevitable. HEERO offers a solution that intelligently combines ecology and economy. You not only ensure compliance with current and future municipal regulations, but also protect investments already made in expensive special bodies and sustainably reduce your operating costs.
By continuing to use existing vehicles in terms of a circular economy, you make an active contribution to resource conservation. HEERO is more than just an outfitter; we are your innovative partner accompanying you from analysis and funding to implementation. Set the course now for a future-proof fleet.
