Purpose and function of the engine mount

The engine mount in the BMW i3 I01 with the Rex system is responsible for the rigid yet flexible seating of the powertrain within the engine bay. A correctly selected element from the Engine mounts category:

• stabilizes the position of the powertrain during acceleration and braking,
• reduces vibrations transmitted to the chassis and the vehicle interior,
• decreases the load acting on other mounts and auxiliary components,
• supports the correct geometry of the powertrain in hybrid mode.

As a result, ride comfort and handling precision remain at the level expected from the BMW brand, and the powertrain operates under stable mechanical conditions.

Benefits of using an original BMW component

The engine mount dedicated to the BMW i3 I01 Hybrid Rex has been designed for the specific architecture of the body and powertrain of this model. This means:

• factory fitment to the mounting points on the chassis and the powertrain,
• preservation of the stiffness and damping characteristics specified by the manufacturer,
• no need for modifications or adaptations during installation,
• consistency with other elements from the Engine mounts group in this model.

Such a solution allows for maintaining powertrain operating parameters in accordance with BMW's design assumptions, which is important for both durability and operational safety.

Characteristics of the used component

The offered engine mount is an aftermarket part sourced from dismantling. A used component of this class is a reasonable choice when:

• you are looking for a technically sound replacement at an attractive price,
• you want to maintain the original BMW mounting specification,
• you want to reduce repair costs while maintaining proper powertrain operation.

Selecting the correct mount has a direct impact on reducing knocks, vibrations, and unwanted noises while driving, especially during load changes and the operation of the Rex unit.

Professional installation and system diagnostics

When replacing the engine mount in a BMW i3 I01 Hybrid Rex, it is worth paying attention to the condition of other elements from the Engine mounts group and ensuring all connections are tightened correctly according to service procedures. Installation in a specialized workshop is recommended, which will:

• verify the condition of other mounts and associated components,
• check for any play and incorrect stresses in the powertrain,
• confirm the absence of collisions with other components after installation.

This approach minimizes the risk of repeat repairs and allows you to fully utilize the design potential of the BMW i3 powertrain.
