At IAA Transportation 2026, Bosch presented a broad portfolio of commercial vehicle technology spanning electric, hydrogen and fuel cell powertrains alongside driver assistance, connectivity and vehicle computing. The company’s new rigid e-axle, fuel cell systems and hydrogen engine components target decarbonization across truck and bus fleets, while new camera, radar and computing hardware address the rising complexity of software in modern commercial vehicles.
Electric, fuel cell and hydrogen powertrains
The headline product is a new rigid e-axle, integrating the electric motor and transmission for commercial vehicles weighing 18 to 49 tonnes. It’s a lighter, more efficient alternative to a conventional electric centre drive, according to Bosch, and paired with silicon carbide inverters rated up to 99 percent efficiency, the combination significantly cuts operating costs in freight transport. A global manufacturing and supply network is built to deliver the axle directly to sites in every relevant market.
Keeping that electric powertrain cool is the job of a new high-voltage blower module for 800-volt architectures, developed specifically for electric commercial vehicles and off-highway use. The module delivers on-demand cooling for key components, reducing energy consumption and helping extend range and efficiency.
Where full electrification isn’t yet practical, Bosch is hedging with hydrogen. Its fuel cell systems span 100 to 300 kilowatts, covering city buses, long-haul trucks and stationary applications, while a parallel hydrogen combustion programme has supplied injectors, control units and sensors for direct and intake manifold injection, plus hydrogen tank system components, to test vehicles and fleets worldwide since 2025.
Because the hydrogen engine builds on established architectures, automakers can keep their existing development and production lines, Bosch notes, and the approach requires virtually no rare earth elements or precious metals. The company’s alternative-fuel portfolio extends further still, covering natural gas, ethanol and methanol for specific regions and applications.
For the fleets and vehicles that are hardest to electrify at all, Bosch offers a cloud-based Digital Fuel Twin. The software tracks fleet use of renewable synthetic fuels such as hydrotreated vegetable oil and documents the resulting reduction in emissions.
Joint venture to expand smart actuator portfolio
The powertrain push isn’t happening in isolation. In May 2026, Bosch announced plans to establish a joint venture by the end of the year with Brakes India Private Limited and Wheels India Limited, both subsidiaries of the TSF Group. Subject to official approval, the venture would expand Bosch’s portfolio into smart actuators for compressed air generation, compressed air treatment, air suspension and parking brakes, a move the company frames as strengthening its position in the commercial vehicle segment and advancing software-defined, connected transportation.
Sensors, software and the software-defined truck
Bosch’s answer to new EU rules on driver monitoring, mandatory for all newly registered trucks from mid-2026 to help prevent accidents caused by inattention or fatigue, is a digital side mirror that folds a driver-attention camera into the left display, eliminating the need for a separate unit. Two European truck manufacturers already fit it as standard. For now a separate control unit processes the image data, though Bosch expects a central domain controller to take over that task as vehicle architectures consolidate.
The MPC4 multipurpose camera, which Bosch calls the first to fuse data from a truck’s numerous surround sensors, brings a twentyfold jump in computing power over its predecessor, with AI used to sharpen functions such as lane-departure warning and emergency brake assist. It enters production in 2027, the same year Bosch introduces a new seventh-generation radar sensor built around waveguide antenna technology and an in-house processing chip.
On the connectivity side, Connected Map Services analyse real-time data on accidents, wrong-way drivers and hydroplaning to proactively control driver assistance systems, while the fleet management xtended access system lets operators control vehicle access through a physical key or smartphone app.
Underpinning all of it are the central E/E architectures Bosch is building around scalable vehicle computers, including a cockpit integration platform and a vehicle integration platform spanning the motion, energy and body domains. Bosch subsidiary ETAS supplies the software layer, offering a vehicle platform suite based on the open-source Eclipse S-CORE initiative alongside a diagnostic approach built on the ASAM SOVD standard, designed to help workshops pool vehicle data and spot faults faster.
The rest of the release reads like the supporting cast, steering and occupant-protection systems built for the same electrified platforms, including the electromechanical ServoE steering system, which runs on electric power alone, and airbag control units that automatically disconnect a truck’s high-voltage battery in a collision. Between the MPC4 camera and new radar sensor landing in 2027, and ETAS’s software and diagnostic platforms already spreading across vehicle architectures, Bosch’s commercial vehicle lineup looks set to keep expanding through the coming year, powertrain and software moving in step.
