What is the fuel consumption of the BMW 523?

[MacLucas]

The BMW 523 has a fuel consumption of 9.4L~12.1L per 100 kilometers. Below is a related introduction to the BMW 5 Series: Exterior: The new 5 Series adopts BMW's latest design language, featuring more bold and striking lines in its appearance. The front face of the new car uses a design template that integrates the kidney grille with the headlights, enhancing the visual horizontal extension. Dimensions: The new car measures 5087/1868/1500mm in length, width, and height, with a wheelbase of 3108mm. Powertrain: It is equipped with a model-specific inline 4-cylinder turbocharged engine, with a maximum torque of 3.0T engine and a maximum power output of 335kw at 5800—6000rpm.

I drive a 2010 BMW 523Li, which is quite fuel-thirsty. The 2.5L inline-six engine paired with a 6AT transmission consumes around 11-12 liters per 100km when shuttling kids to school in city traffic, and can reach 14 liters in heavy congestion. It's more fuel-efficient when cruising at 80km/h on elevated roads, averaging about 8 liters. While it's safer to use 95-octane gasoline, I've tried 92-octane from private gas stations without triggering any warning lights, though the fuel cap recommends 95 or higher. The newer 5 Series with 2.0T engines are actually more fuel-efficient - this is one area where the older model can't compete.

Back in the day, our car enthusiast circle always said BMW's straight-six engines were gas guzzlers. The N52 engine in the 523 model would easily consume 10-12 liters per 100 kilometers when driven gently. Once on the highway, I reset the trip computer and maintained a steady 120 km/h, yet it still showed 7.9 liters. Looking back now, it burned 2 liters more than the later N20 turbocharged engine, but that silky smoothness of the six-cylinder is something a four-cylinder just can't match. The 66-liter fuel tank was quite large, allowing over 500 kilometers on a full tank, but if you stepped on the gas too hard, you'd become a regular at the gas station.

My friend just bought a used 523, and the actual fuel consumption was shocking: 13L/100km for commuting and 9L on the ring road. The fuel consumption of such an old car is highly dependent on its condition—his car has 100,000 km without carbon cleaning. I recommend checking the oxygen sensor and air filter. After I replaced the oxygen sensor on my car, the consumption immediately dropped from 11L to 9.8L. Use 95-octane fuel to prevent knocking, and pay special attention to using the correct oil grade! The fuel gauge in German cars shows about 0.5L lower than the actual level, so don’t fully trust the onboard computer.
