Technical characteristics of the Rex unit

The presented engine belongs to the Engines category and is a component of the Range Extender hybrid system in the BMW i3 I01. The two-cylinder petrol design has been optimized for operation as a generator, with an emphasis on rotational stability, refinement, and reduced fuel consumption. The use of a compact cylinder layout facilitates a small footprint, which simplifies integration with the factory subframe and vehicle ancillaries.

The engine runs on petrol, allowing for easy operation in both urban and extra-urban conditions, while maintaining predictable starting parameters and performance across a wide temperature range. The low number of cylinders results in a simplified mechanical architecture, which facilitates servicing and diagnostics in specialized workshops.

Purpose and compatibility

The unit was developed specifically for the BMW i3 I01 in the Hybrid Rex version, where it is responsible for maintaining the energy level in the traction battery during longer journeys. Thanks to the factory fitment for this model, compatibility with the original mounting points, cooling system, as well as the vehicle's fuel and electrical installations is maintained.

The engine has a dedicated OEM part number and associated interchangeable numbers, which facilitates precise identification via VIN or manufacturer markings. This selection method minimizes the risk of incompatibility and is recommended for professional repairs of electric vehicles with a Range Extender module.

Condition, mileage, and benefits of installation

The offered unit is a used petrol engine with very low, documented mileage, which in practice means a limited degree of mechanical wear and less usage compared to typical engines from the secondary market. Such mileage is particularly important in the case of precision units working with a hybrid system, where operational stability and durability reserves have a direct impact on user comfort.

Choosing an original engine with low mileage allows you to:

• maintain the factory operating characteristics of the Range Extender system,
• reduce the risk of failure after installation due to lower operational wear,
• optimize repair costs compared to purchasing a new unit.

Professional selection and technical expertise

When selecting an engine for the BMW i3 I01 Rex, it is crucial to compare the OEM part number and interchangeable numbers with the vehicle documentation and data from service systems. Proper identification using manufacturer markings and the VIN helps avoid problems with the compatibility of accessories, controls, and engine control unit software.
