The EF18 SZM is specially designed to cater to individual requirements in the combined transport sector. We not only offer a choice of battery sizes for the semi-trailer truck to cater to specific trip profiles, for example, but also two different drivetrain variants. The electric motors deliver an output of 440 kW or 550 kW, according to preference. Both variants guarantee strong performance even on extreme gradients (16%) and are a delight to drive, whatever the route. In short: the EF18 SZM introduces the experience and technical expertise of EFORCE to the world of combined transport.

How you

  • 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 EF18 SZM 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 EF18 SZM therefore needs just 1/3 of the energy of a diesel vehicle. As an emission-free vehicle, the EF18 SZM does not emit any harmful substances such as particulates or CO2.

    The EF18 SZM contributes to a significant reduction
    in harmful emissions.

  • High cost-effectiveness

    Low consumption, low maintenance costs, lower duty and tax: the EF18 SZM 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 EF18 SZM’s sophisticated technology puts it ahead of the game. Because emission-free vehicles are exempt from various duties and taxes, the EF18 SZM is able to save you further costs:, 100% of the performance-related heavy vehicle fee (HVF) in Switzerland, for example.

    Profitable investment
    An EF18 SZM 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 EF18 SZM’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 EF18 SZM chassis depends on the battery pack selected and lies between 8 and 9 tonnes – leaving 10 to 11 for the body and payload. With its low noise emissions, the EF18 SZM is perfect for urban operations, including sensitive early-morning or late-night deliveries, for example.

  • Impressive output

    The EF18 SZM’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 EF18 SZM 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 EF18 SZM 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 EF18 SZM’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. They are liquid-cooled and linked to the vehicle’s air conditioning system, which means that they can be actively heated or cooled. Depending on their size, the batteries allow a range of up to 350 km and can be fully charged overnight in five hours (20-100%, charging via AC). Fast charging using DC (in accordance with the CCS standard) reduces this charging time to an impressive one hour or less, depending on the size of the battery. 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. For up to 350 kilometres more.

    Charging time
    Thanks to ABB fast charging technology (up to 350 kW DC)
    the EF18 SZM is fully charged after just one hour.
