Model Details

Enhance your HO scale model railway with the Viessmann 8451 CarMotion Sound Retrofit Kit, designed for Mercedes-Benz round bonnet vehicles in red. This precision-engineered sound module brings authentic engine acoustics to CarMotion road vehicles, significantly increasing realism across modern and classic road traffic scenes on HO scale layouts. Ideal for logistics depots, rural haulage, industrial operations, and mixed traffic environments, it integrates seamlessly into the Viessmann CarMotion system.

The retrofit kit reproduces realistic diesel engine start-up, idle, acceleration, and shutdown sounds, along with driving noise effects such as gear changes and braking. It is designed to synchronise with CarMotion vehicle movement, ensuring that sound output matches operational behaviour for a highly immersive effect. Control is handled through the CarMotion system, including infrared commands and compatible control interfaces.

According to manufacturer specifications, the module is designed for easy installation into compatible Mercedes-Benz round bonnet CarMotion vehicles. It uses a dedicated plug-in interface and includes an integrated speaker system optimised for compact HO scale cab interiors. The sound profile is specifically tuned for round bonnet engines to match prototypical characteristics.

The Viessmann 8451 module installs directly into compatible CarMotion vehicles via a dedicated interface, replacing or supplementing existing internal components. It is fully integrated into the CarMotion ecosystem, ensuring synchronised interaction with vehicle movement, lighting functions, and convoy operation. The compact speaker system is optimised for clear sound reproduction within HO scale cab environments, while maintaining space efficiency within the chassis.
