Purpose and function in the powertrain

This mount plays a key role in stabilizing the powertrain in the BMW i3 I01 with the Rex system. It is responsible for transferring loads from the engine to the chassis, controlling movement during acceleration and braking, and reducing vibrations transmitted to the cabin.

Thanks to its factory design, the component works in harmony with other powertrain support points, maintaining the correct geometry of the engine-transmission-generator assembly. This is important for both driving comfort and the durability of adjacent components, such as hoses, wiring harnesses, or exhaust system elements.

Benefits of using an original mount

Using an original engine bracket in the hybrid BMW i3 I01 allows you to maintain the parameters specified by the vehicle manufacturer. In practice, this means:

• correct positioning of the powertrain relative to the chassis,
• consistent cooperation with other engine mounts,
• reduction of vibrations and knocking during load changes,
• reduced risk of stress on neighboring components.

For the user, this translates into stable handling, predictable vehicle behavior, and more comfortable operation of the hybrid powertrain with the Rex generator.

Product characteristics and fitment

The engine bracket was designed by BMW specifically for the i3 I01 Hybrid Rex powertrain, ensuring full compatibility with factory mounting points. The component has a dedicated OEM part number and associated interchangeable numbers, which facilitates clear identification and selection of the correct variant for a specific vehicle configuration.

The product belongs to the Engine mounts group, making it optimized for vibration damping and handling dynamic loads. This is particularly important in hybrid designs, where the powertrain generates varying loads depending on the operating mode.

Condition and service application

The item is offered in a used condition, allowing for an economical repair while maintaining the original manufacturer's specifications. This is a practical solution in situations where the existing mount has suffered mechanical damage, corrosion, or shows excessive play affecting powertrain performance.

Before installation, a standard visual inspection and verification of the mounting points on the vehicle are recommended. A correctly selected and installed engine bracket restores proper support for the powertrain, which is essential for both driving comfort and operational safety.

Selection support and technical knowledge

For precise fitment, manufacturer markings, including the OEM part number and interchangeable numbers, are helpful, as they allow you to verify compatibility with a specific version of the BMW i3 I01 Hybrid Rex. If in doubt, it is worth comparing the markings with the vehicle documentation or the existing component.
