This petrol engine had a displacement of 2.5 liters, producing a maximum power output of 150 horsepower (112 kW) at 5,800 rpm. The peak torque was 210 Nm (155 lb-ft), available between 3,500 and 4,500 rpm. A five-speed manual transmission and a four-speed automatic were the primary transmission options for this model.

Drive Type: The BMW 523i featured rear-wheel drive, like most of its predecessors and successors in the 5 Series lineup at that time.

This included leather upholstery, power-adjustable seats, climate control, audio systems, and more advanced features like navigation in some markets.

Safety Features: For its time, the E39 was considered safe due to features such as anti-lock braking (ABS), driver and passenger airbags, and a rigid body structure designed to absorb impact. Some higher-end trim levels might have included side airbags as well.

Reliability and Maintenance: The reliability of BMWs has historically been high, with the E39 series being no exception. However, issues like engine overheating and problems with the M52B25's timing chain could arise, requiring specific maintenance to prevent major issues.

Overall Performance and Driveability: The 523i provided good fuel economy and decent performance considering its time, making it suitable for daily driving as well as long trips where a comfortable pace was preferred. Its handling and dynamics were characteristic of BMW's reputation for providing engaging driving experiences.

Market Positioning: When new, the E39 523i competed with other executive sedans and wagons in terms of performance, comfort, and features. It positioned itself well against its main competitors, offering a compelling blend of style, performance, and luxury at an affordable price point for many markets.

Rarity and Collectibility: As a base model within the E39 lineup, the 523i may not hold the same collectible value as higher-performance variants like the M5 or even sportier models. However, its availability across various markets means it's still sought after by enthusiasts for daily driving and occasional track use.

Conclusion: The BMW 523i was a practical, yet engaging car that suited many drivers' needs during its production period from 1995 to 2000. It served as an entry-point into the E39 lineup, offering good performance, comfort, and value within the executive sedan/wagon segment of its time.
