Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1988 325iX.
The 1988 BMW 325iX Electric pairs its underlying 325iX platform with an electric powertrain to create a distinct variant within the model's history. Despite the inherent complexities of such a configuration, the vehicle boasts an exceptionally clean track record defined by zero recalls and just five total owner complaints. The few issues that were reported predominantly cluster in the engine and engine cooling systems alongside visibility concerns, rather than reflecting systemic platform flaws. This positions the 1988 model year at a high point in the model's reliability history, indicating a robust overall execution that offers researchers a remarkably stable, low-issue baseline for studying this specific electric application.
