525 currently available models have a 0-100 km/h acceleration time of 8.6 seconds. The BMW 525 currently available models are positioned as mid-to-large-sized sedans and adopt a front-engine, front-wheel-drive layout. The BMW 525 currently available models only include the 2020 version, with a total of two variants, both compliant with the China VI emission standards. Relevant information about 0-100 km/h acceleration is as follows: 1. 0-100 km/h acceleration refers to the time taken to accelerate from 0 to 100 km/h, which is the most intuitive reflection of a car's power. 2. Generally, compact cars with 1.6L engines achieve 0-100 km/h acceleration times between 11 to 13 seconds, mid-sized cars with 2.0T engines between 7 to 8 seconds, while supercars mostly achieve acceleration times of less than 3.8 seconds.

Back when I drove the old 525, I tested it and the dashboard showed a top speed of around 235, but the electronic speed limiter was strictly enforced. Now, with the new 2.0T low-power engine, although the specs are similar, the increased weight has actually lowered the top speed to 230. Testing such speeds on the highway requires finding a straight, open stretch, and you also need to watch tire pressure and temperature, as the car starts to feel unstable at those speeds. Honestly, even driving at 160 feels noisy, and there's really no need to chase extreme speeds—not only does fuel consumption spike instantly, but even a small pothole could cause a loss of control.

Just a few days ago, I took a friend to test drive the new 525Li, and the salesperson clearly stated that the electronic speed limiter is set at 230 km/h. The car's powertrain features a B48 engine paired with a ZF 8AT transmission, theoretically capable of higher speeds but factory-locked. I've driven a German-spec 520d without a speed limiter, and the same chassis easily exceeded 240 km/h. To be honest, such speeds are completely unnecessary in China, where highways max out at 120 km/h. Pushing beyond 200 km/h is just wasteful on fuel and illegal. If you really want to experience strong acceleration, it's better to use Sport mode—it makes city driving more thrilling from a standstill.

Tested the F18 generation 525, when flooring the accelerator, the needle gets stuck at 235 km/h and won't go further. BMW's approach is quite —it protects the engine while avoiding legal risks. Remember a fellow car enthusiast who flashed the ECU to remove the speed limiter, reaching 245 km/h but severely damaging the car, with the transmission oil temperature warning light coming on immediately. The original Michelin tires are designed for a top speed of 250 km/h, with the risk of a blowout doubling beyond that limit. Now, the G38 chassis cars are heavier, with weaker acceleration push but more stable cruising.

Those who are into know that the 530 is the real performance benchmark. The 525's 184 horsepower can barely hit 230 km/h at most. During the last track day, we specifically tested it—accelerating from standstill to 200 km/h took about 25 seconds, and every additional 10 km/h beyond that cost several more seconds. Upgrading to an MP exhaust might improve the sound but won't help with top speed. Two key points to note: First, you must turn off ESP to unleash full power. Second, brake pads start to degrade noticeably at speeds above 210 km/h—regular commuter cars really aren't built for prolonged high-speed runs.

According to BMW's technical documentation, the 525 is calibrated for a top speed of 229 km/h in compliance with ECE regulations. However, under actual driving conditions on flat roads using 98-octane fuel with additives, the speedometer briefly showed 232 km/h. Interestingly, running the air conditioning at maximum power has a noticeable impact, with summer tests showing about 5 km/h less than winter speeds. It's advised not to dwell too much on this parameter—the 525's strength lies in its mid-range acceleration between 80-160 km/h, making it more responsive than some sports cars when overtaking.
