Technical Characteristics of the BMW i3 Rex Engine

The presented gasoline engine has been designed as a compact power source for the Range Extender system in the BMW i3. Its two-cylinder, spark-ignition design works with the vehicle's high-voltage system, ensuring stable generator power supply while maintaining low weight and reduced vibrations.

The cylinder arrangement and operating parameters of the unit have been selected for high efficiency within a narrow RPM range, typical for engines primarily operating as power generators. This makes the powertrain well-suited for prolonged, steady-state operation, which is important when used in extended range mode.

Intended Use and Compatibility

The engine is intended for use in the BMW i3 I01 generation, specifically in the hybrid Rex version. The unit's design is integrated with the electric vehicle's architecture, making it particularly important for ensuring correct interaction with the control electronics and energy management system.

The original designation of the unit and its assignment to a specific model configuration facilitate the selection of the correct engine when replacing a damaged powertrain. Additionally, the availability of dedicated replacement numbers allows for precise matching of the component to a specific equipment version and model year.

Condition, Mileage, and Benefits of Purchasing a Used Engine

The offered engine is from the aftermarket, which significantly reduces repair costs compared to a brand-new unit. The low mileage of the unit translates to limited wear on moving parts, which is beneficial for its further operation in a hybrid vehicle.

Purchasing a used BMW engine for the i3 Rex is particularly attractive for workshops specializing in electromobility and for informed users who want to restore full vehicle functionality while staying within a reasonable budget. Maintaining the original powertrain architecture promotes seamless integration with the existing control system.

Benefits of Using an Original BMW i3 Rex Engine

• maintaining the factory operating characteristics of the Range Extender system,
• correct interaction with the control electronics and energy management system,
• structural consistency with other BMW i3 powertrain components,
• opportunity for cost optimization of repairs through the use of a pre-owned unit.

For users planning a broader modernization or powertrain repair, using an original engine from the same model family minimizes the risk of compatibility issues and reduces the time required for adaptation in the vehicle.
