The main differences between BMW 520 and 525 are: 1. Different engines. The BMW 520 is equipped with an inline 6-cylinder engine and an 8-speed automatic transmission, with a maximum power of 177 horsepower and a peak torque of 230 N·m. The BMW 525 is equipped with an inline 6-cylinder camshaft engine and a 6-speed automatic transmission, with a maximum power of 160 horsepower and a peak torque of 250 N·m. 2. Different comprehensive fuel consumption. The MIIT comprehensive fuel consumption of the BMW 520 is 9.1L. The MIIT comprehensive fuel consumption of the BMW 525 is 9.5L. Additional content: The front face of the new BMW 5 Series adopts a design similar to the 7 Series, with a larger grille size and thicker internal trim strips. The grille extends downward to the bumper, and the rounded shape makes the front face look more refined and three-dimensional. The headlights have changed most significantly, with the elimination of the iconic angel-eye headlights and the adoption of the same headlight design as the BMW 3 Series. The internal double L-shaped daytime running lights are straighter and more streamlined.

As a BMW enthusiast, the main difference between the 520 and 525 lies in their power tuning. The 520 uses a 2.0-liter low-power engine with around 184 horsepower, offering smoother acceleration with a 0-100km/h time of about 8 seconds, making it comfortable and sufficient for city driving. The 525, on the other hand, is a high-power version of the same displacement, delivering over 252 horsepower and more aggressive acceleration, achieving 0-100km/h in roughly 6.8 seconds, which provides more confidence for highway overtaking. In terms of fuel consumption, the 520 averages 8-9L/100km, while the 525 may consume 9-10L, making the 520 slightly more economical. Regarding features, the entry-level 525 often includes basic navigation or premium audio systems, whereas the 520 is more basic but offers greater customization options. The price difference is around 30,000-40,000 RMB. If you prioritize driving pleasure and additional features, the 525 is more worthwhile; for daily commuting, the 520 is sufficient, saving you money and fuel. Both models have reliable chassis and build quality, but the best way to appreciate their performance differences is to test drive them.

I'm considering economy and practicality. The core differences between the 520 and 525 are cost and efficiency. The 520 delivers 184 horsepower, which is less powerful but slightly more fuel-efficient, averaging 8 liters per 100 km, with slightly cheaper insurance and maintenance. The 525 offers 252 horsepower, with fuel consumption rising to over 9 liters per 100 km—faster acceleration but slightly higher daily costs. The 520 is a few thousand yuan cheaper, making it more cost-effective for those on a tight budget. The configurations are similar; the 520 is basic but sufficient for commuting, while the 525 has extra features that may not justify the added cost. In city driving, the differences are minimal—unless you frequently drive on highways, the 520's advantages are clear. With nearly identical maintenance costs, the 520 is a more hassle-free choice in the long run. When choosing, consider your budget and driving habits—for practicality, the 520 is a solid pick.

From a mechanical perspective, the 520 and 525 share identical engine hardware but differ in ECU tuning. The 520 delivers lower power at 184 horsepower with smoother turbo engagement, while the 525 offers higher power at 252 horsepower and more responsive acceleration, resulting in a nearly 2-second gap in 0-100 km/h times. In terms of features, the 525 often comes standard with navigation or LED lighting groups, whereas the 520 may lack some but is upgradable. Chassis and brake designs are identical. In real-world driving, the 520 provides adequate and stable performance, while the 525 delivers stronger acceleration. Fuel consumption differs by less than 1L per 100 km, with similar maintenance costs and high reliability. Power output is the primary differentiator—the 520 suffices for gentle driving.

When making a car purchasing decision, the price difference of 30,000-40,000 yuan between the 520 and 525 is crucial. The 520's 184 horsepower is perfectly adequate for daily commuting, while the 525's 252 horsepower offers an enhanced acceleration experience. Their configurations are largely similar, with the 525 possibly including more standard features like power seats. There's no difference in comfort and safety; the 520 is slightly more fuel-efficient, but the gap is minimal. If budget is tight, the 520 is the more economical choice; with extra funds, the 525 provides additional driving pleasure. Test driving both models is the most direct way to compare their performance.
