Wirtgen will unveil five world premieres in the cold milling and recycling segments, in addition to several innovations in the slipform paving and surface mining, at bauma 2025.
The new machines from the manufacturer include the new W 250 XF large milling machine and the new generation of WR series machines.
Cold milling machines
With a total of 12 cold milling machines, Wirtgen will present a broad cross-section of its overall product portfolio. Highlights include the world premieres of the battery-electric small milling machine W 50 Re (a technology project) and the large milling machine W 250 XF. The company will also present the world’s most powerful milling machine with a version featuring an optional operator’s cab.
During the development of the W 250 XF, Wirtgen focused on the realization of maximum productivity and reduced emissions.
The dual engine concept with two 18-litre John Deere engines delivers a maximum power output of 1,207 hp. Wirtgen and John Deere tuned the engine torque to meet the specific requirements of the cold milling process.
The Mill Assist machine control system regulates the power output of the two engines according to demand, to ensure the most efficient use of the machine. Automatic mode ensures a favourable working balance between performance and cost. It also enables selection of three different working strategies that optimize the process for cost, performance or quality. The machine at Wirtgen’s bauma booth is also fitted with a cab that offers the operator a comfortable, low-fatigue workplace and provides effective protection against the weather and noise.
W 210 XF
Also new in Wirtgen’s product portfolio is the large milling machine W 210 XF. With an engine power output of 778 hp and milling widths between 2 metres and 2.5 metres, the machine is ideally equipped for a wide range of applications and high daily productivity. The Dual Shift powershift transmission enables a wide range of selectable milling drum speeds. The lower range of milling drum speeds enables significant reductions of fuel consumption, pick wear and noise emissions. The upper range of milling drum speeds makes it possible to achieve high area performance with a high-quality milling pattern, even at the maximum milling depth of 33 cm.
New cold recyclers and soil stabilizers
For the cold recycling and soil stabilization sectors, Wirtgen will present a range of machines including the three new WR 200|240|250 X models.
The focus in the development of these machines was set on ensuring easy and ergonomic operating, high performance and outstanding mixing quality. To achieve its goal, Wirtgen embarked on a comprehensive revision of both the operating concept and the design of the operator’s cab itself.
A new multi-function joystick, fingertip control and height adjustment with the multi-function armrest contribute to the improved ergonomics of the operating concept. In addition to digital process monitoring, the large machine control panel display offers a variety of automated functions, application-relevant displays and CoPilot. The Wirtgen Group’s CoPilot provides suggested courses of action during the work process, offers interactive tutorials and a self-training function for familiarization with the machine, and its functions, with animations displayed directly on the machine’s control panel.
The field-proven Duraforce milling and mixing rotor guarantees consistently high milling and mixing performance.
The Rock Crusher WRC 240(i) will be on display alongside the new WR series machines. It crushes coarse rocks and stones, as found in hand packed stone layers and stony ground, in-situ and homogeneously mixes the resulting material in a single pass. With a working width of 2.3 metres and a depth of up to 51 cm, it can achieve cutting, crushing and mixing rates of up to 600 tons per hour.
The SP 33 slipform paver
Also, at bauma, Wirtgen is showing the compact SP 33, its newest slipform paver for the construction of monolithic concrete profiles.
Thanks to its modular construction concept and a wide range of setting options, the machine can be configured for use in almost all situations encountered on construction sites. In offset configuration, it can pave curb and gutter profiles, rectangular profiles and concrete barriers up to 1.3 metres in height as well as sewer and gutter profiles. Concrete slabs with a paving width of up to 2.2 metres can also be achieved without issue, and a width of 2.4 metres in combination with a trimmer.

In Crosspave configuration, the track units are turned by 90 degrees and the machine then paves transverse to the direction of travel. The slipform mould is centrally mounted under the machine, enabling the paving of concrete slabs with widths of up to 3 metres.
The quick and easy conversion from one paving mode to the other makes the machine extremely versatile. The new operating concept with an event-driven graphic display assists operators in their work with both paving options.
The eco mode detects the current paving situation without the need for manual intervention by the operator and ensures automatic, load-optimized regulation of engine output for low fuel consumption and low emissions.
The AutoPilot 2.0 stringless machine control system is also usable with the SP 33. This eliminates the need for control by a physical stringline, which results in considerable savings in terms of time and effort and increases the safety of the personnel employed on the construction site.
At the same time, the system precisely controls both the height adjustment and steering of the machine. AutoPilot 2.0 also enables fast and precise paving of tight radii and complex geometries.
In the inset paving segment, Wirtgen will be showing an SP 94i paver with an integrated dowel bar inserter (DBI) and a texture curing machine TCM 180i. The placement of reinforcement with a DBI increases the degree of automation, improving the efficiency of the overall paving process and the paving quality.
The placer/spreader WPS 102i is a useful addition to a paving train when paving concrete with pre-placed steel rebar reinforcement. It is deployed ahead of the slipform paver and enables feeding of material from trucks from the side.
