In addition to the standard models, EFORCE offers the option of individually developed special-purpose versions. Numerous projects, such as an electrically powered refuse truck with a Geesinknorba body, are currently in development or nearing completion. Despite all the variety, one thing remains constant: the quality of our innovative Swiss engineering.

  • Unbeatable eco-efficiency

    At best, a conventional diesel drive system has a tank-to-wheel energy efficiency of 43%. This means that over 57% of the primary energy cannot be used as drive energy. In contrast, the EF26 KSF has a battery-to-wheel efficiency of 91%. This is partly due to the fact that brake energy is directly recuperated, which is a major benefit particularly in stop-and-go traffic. The EF26 therefore needs just 1/3 of the energy of a diesel vehicle. As an emission-free vehicle, the EF26 KSF does not emit any harmful substances such as particulates or CO2.

    The EF26 KSF contributes to a significant reduction
    in harmful emissions.

  • High cost-effectiveness

    Low consumption, low maintenance costs, lower duty and tax: the EF26 KSF clearly has the edge over conventional diesel vehicles in urban situations. With diesel vehicles, frequent stopping, starting and load changes lead to major brake wear, resulting in higher maintenance and service costs. Here, the EF26 KSF’s sophisticated technology puts it ahead of the game. Because emission-free vehicles are exempt from various duties and taxes, the EF26 KSF is able to save you further costs: 100% of the performance-related heavy vehicle fee (HVF) in Switzerland, for example.

    Profitable investment
    An EF26 KSF clocking up anything above 50,000 km per year is more economical than a diesel truck.
    Covering this kind of distance, the additional cost of an EFORCE can be offset within four years thanks to exemption from the HVF and various taxes.

  • All-round practicality

    The EF26 KSF’s above average range, adaptability, high load capacity and optimal weight utilisation make it ideal for day-to-day operations. The chassis is suitable for all popular body variations. The modular battery system allows a range of 100-350 km. The weight of the EF26 KSF chassis depends on the battery pack selected and lies between 10 and 11 tonnes – leaving 16 to 17 for body and payload, and 17 tonnes for trailer with payload. With its low noise emissions, the EF26 KSF is perfect for urban operations, including sensitive early-morning or late-night deliveries, for example.

  • Impressive output

    The EF26 KSF’s highly efficient, robust electric motor and latest-generation modular lithium-ion batteries result in outstanding performance. In addition to an unrivalled range of up to 350 km, what is most noticeable about the EF26 KSF is its acceleration. The electric drive system’s high torque is available from the word go. This means that, in urban stop-and-go traffic, the EF26 KSF is able to out-accelerate comparable diesel vehicles. And with a top speed of 85 km/h, it can also keep pace on highways and motorways.

    Thanks to high torque, the EF26 KSF’s acceleration figures are significantly
    better than those of conventional diesel trucks

    EF18 Vorteile Performance

  • Reliable energy

    At the heart of the EFORCE trucks are the specially developed, modular lithium-ion batteries. It is possible to have these cooled with a liquid medium and connected to the air conditioning system of the vehicle. Depending on their size, the batteries allow a range of more than 500 km and can be fully charged overnight (20-100%, charging via AC). Fast charging using DC (in accordance with the CCS standard) reduces this charging time. With fast company charging stations and a network of public CCS stations, your vehicles will be ready to set off again in next to no time. 

    Charging time
    Thanks to ABB fast charging technology (up to 350 kW DC)
    the EF26 KSF is available again after just one hour.

Components &

The EF26 KSF is equipped with cutting-edge alternative drive technology: from the drivetrain, with its motors, transmission and motor controls, to the batteries, with their chargers and on-board converters, not forgetting the power distributor. We combine these components to optimum effect, creating compelling, economical, high-performance e-mobility solutions for heavy goods transport. Modular design and redundancy in the drive system ensure high safety and reliability. The drive components, adopted from the world of shipping, have been thoroughly tried and tested.
