The Mercedes-Benz Arocs is a heavy construction truck family built by Mercedes-Benz Trucks, part of Daimler Truck. First introduced in 2013, it is the brand's dedicated construction and heavy-haulage range, covering tipper chassis, construction tractors and all-wheel-drive chassis from roughly 18 tonnes up to 44 tonnes gross combination weight, with heavy-haulage variants rated for up to 500 tonnes. This evolution profile is based on AssetBase data.
This profile groups the Arocs lineage into three major phases: the first-generation diesel range launched in 2013 with Euro VI engines from the outset, the updated diesel range from 2019 with the Multimedia Cockpit, and the new battery-electric eArocs 400. The current diesel line-up uses a six-cylinder in-line engine across a wide output band, offered as tipper chassis (K), construction tractors (LS) and all-wheel-drive chassis (AK) from 4x2 to 8x8. The eArocs 400 replaces that driveline with a central electric motor and lithium iron phosphate batteries.
The Arocs is used for construction transport, off-road haulage and heavy transport. Generation identity matters because the same family name now covers Euro VI diesel powertrains and a fully electric drive, several duty classes and drive configurations, and gross weights from standard 40-tonne rigs to 500-tonne heavy haulage. For valuation, fleet and ESG workflows, two records that both read "Mercedes-Benz Arocs" can describe very different assets.
A dedicated construction truck family that now spans Euro VI diesel and battery-electric drive, organised in this profile across three major phases.
Mercedes-Benz Arocs evolution at a glance
The Arocs name covers a heavy construction truck family that has run since 2013. Across that span the basic role, a robust on- and off-road tipper, tractor or all-wheel chassis for construction and heavy transport, has stayed constant, while the cockpit, electronics, driver assistance and now the powertrain itself have changed. The same model name can therefore describe a 2013 first-generation diesel, a 2019 Multimedia Cockpit diesel, a 500-tonne heavy-haulage rig or a battery-electric eArocs 400.
Because the diesel range and the electric branch developed in sequence and overlap in use, this profile groups them into datasheet-backed phases rather than a single one-row-per-generation timeline.
The takeaway: one family, three phases and two powertrains. The 2019 diesel range is the phase described directly by the uploaded model datasheets, with the 2013 launch and the eArocs 400 framing the lineage on either side.
Current or latest datasheet-covered line-up
The latest Arocs line-up has two parts: a broad Euro VI diesel range and the new battery-electric eArocs 400. The diesel range is organised by duty class rather than by a single model: tipper chassis carry the K (Kipper) code, construction tractors carry the LS code with the L cab, and all-wheel-drive construction chassis carry the AK code, available from 4x2 up to 8x8.
The diesel models share a six-cylinder in-line engine to Euro VI, paired with the Mercedes PowerShift 3 automated transmission. Across the uploaded datasheets, outputs run from 175 kW (238 hp) with 1,000 Nm on the Arocs 1824 LS to 460 kW (625 hp) with 3,000 Nm on the Arocs 1863 LS, with the higher-output models using turbocompound technology. Four-axle tipper chassis such as the Arocs 4158 K 8x4 are rated at 425 kW (578 hp) and 2,800 Nm. For the heaviest work, the Arocs heavy-haulage configuration is rated for up to 500 tonnes gross combination weight.
The eArocs 400 is the electric branch. It uses a central electric motor rated at 380 kW continuous and 450 kW maximum, with a three-speed transmission and lithium iron phosphate (LFP) batteries giving 414 kWh installed across two packs. Built as an 8x4/4 chassis with a permitted gross combination weight of 44 tonnes, it offers a range of up to 200 km as a concrete mixer and up to 240 km as a tipper, and supports DC charging at up to 400 kW, recharging from 20 to 80 percent in around 45 minutes.
The main difference across the latest range is powertrain and duty: diesel power and axle class on the K, LS and AK chassis, and battery capacity on the eArocs 400, which sets its range and charging profile.
Major turning points in the model lineage
A handful of changes shape how the Arocs should be understood. The 2013 launch established the Arocs as a clean-sheet construction range, separate from the long-distance Actros, and notably arrived with Euro VI engines from the outset. The 2019 update is the phase fully described by the uploaded datasheets, introducing the Multimedia Cockpit and the option of MirrorCam in place of conventional mirrors, alongside the Predictive Powertrain Control and assistance systems listed across the model sheets.
Two further turning points widen the family rather than replace it. The heavy-haulage configuration, rated for up to 500 tonnes gross combination weight, uses a wear-free fluid Turbo Retarder Clutch as a start-up and braking system for extreme loads. In parallel, the eArocs 400 moves the family to battery-electric drive: an LFP-battery construction truck with a central motor and local zero-emission operation. These branches are not the same asset class as a standard diesel Arocs and should be identified separately.
Variants, body styles and special versions explained
The Arocs name covers more than one technical truck. The model number, drive code, chassis code and the diesel-versus-electric split all point to real differences. In the diesel range a designation such as "Arocs 1863 LS 4x2" encodes a weight class and a power class: the first two digits indicate the gross weight class and the last two a power code, while suffixes such as K mark a tipper chassis, LS a construction tractor with the L cab, and AK an all-wheel-drive construction chassis. The figure 4x2, 6x4, 8x4 or 8x8 marks the axle configuration and how many axles are driven. On the electric side, "eArocs 400" indicates the electric model rather than an engine size. These labels belong here, not in the generation timeline.
Technical evolution and specification signals
The technical profile has shifted across the phases. The 2013 first generation established the diesel construction format with Euro VI engines from launch, and by the 2019 phase the uploaded datasheets show a broad Euro VI diesel range, from 175 kW (238 hp) and 1,000 Nm on the Arocs 1824 to 460 kW (625 hp) and 3,000 Nm on the Arocs 1863, the higher-output models using turbocompound technology. The range pairs the six-cylinder engine with the Mercedes PowerShift 3 automated transmission, Predictive Powertrain Control and, as an option, MirrorCam in place of conventional mirrors.
The most recent step is the electric eArocs 400. It replaces the engine and standard gearbox with a central electric motor rated at 380 kW continuous and 450 kW maximum, a three-speed transmission and LFP batteries giving 414 kWh installed across two packs. It also adds electric and mechanical power take-offs, rated at up to 90 kW (ePTO) and up to 70 kW (mPTO), for construction bodies. The same family now spans two fundamentally different drivelines.
The takeaway: power, torque and energy storage all move across the phases, and the move from diesel to electric is the clearest technical break, so output and energy figures should be read alongside the phase they belong to. A more detailed technical profile is available in AssetBase.
Energy use and lifecycle CO₂ across generations
Energy and emissions behaviour differs sharply across the Arocs phases, driven first by the engine and emission standard on the diesel side and then by the move to electric drive. The diesel models in the uploaded datasheets are all Euro VI, but the datasheets do not print a directly comparable CO₂ figure per model, so cross-model diesel emissions cannot be compared from this data alone. The eArocs 400 carries no local tailpipe emissions, and its datasheet reports energy in battery capacity rather than fuel or CO₂, noting at least 50 percent lower energy use than a comparable diesel.
For practical analysis, operational energy and lifecycle CO₂ should be understood separately. A diesel Arocs consumes fuel per kilometre or per duty cycle, while an eArocs 400 consumes electricity, and each has a different upstream profile. Because the family now spans both, a single "Arocs" record is not enough to estimate emissions: the driveline, energy source and duty cycle all change the result.
EmissionBase® helps separate operational energy from broader lifecycle CO₂ assumptions such as production, battery or engine system, transport, maintenance and end-of-life treatment.
Why generation identity matters
The "Mercedes-Benz Arocs" name alone is not enough to identify the asset. A 2013 first-generation diesel, a 2019 Multimedia Cockpit diesel, a 500-tonne heavy-haulage rig and a battery-electric eArocs 400 share a family name and a construction-truck role, but they differ in cockpit generation, engine or drive type, power, energy source, gross weight class, duty class and electronics.
For asset finance, leasing, residual value, marketplace and ESG workflows this matters in practice. Two records that both read "Arocs" can represent very different trucks with different valuations, maintenance profiles, parts availability, charging or refuelling needs and lifecycle CO₂. Resolving the asset needs the model code, the chassis code (K, LS or AK), the axle configuration, the diesel-versus-electric split and the production year.
The diesel-to-electric divide is the sharpest example. An eArocs 400 and a diesel Arocs 4158 K are both "Arocs", but they have different drivelines, energy systems, charging or fuelling infrastructure and residual-value behaviour. Treating them as one asset type would distort any fleet, valuation or emissions view.
How this model family fits into wider heavy truck coverage
The Arocs sits inside Mercedes-Benz Trucks' wider heavy and medium truck line-up. Adjacent same-make families include the long-distance Actros, the distribution Atego, the municipal Econic and the off-road Unimog and Zetros, plus the electric eActros and eEconic alongside the eArocs 400. Within the Arocs range itself, the heavy-haulage configuration extends the family up to 500 tonnes gross combination weight.
In the wider heavy truck segment the Arocs competes with comparable construction tippers, tractors and all-wheel chassis from other European manufacturers. From a taxonomy perspective the Arocs is a heavy truck within the transportation industry, recorded as a tipper chassis, tractor unit or all-wheel chassis depending on the configuration, and as diesel or electric depending on the driveline.
