The differences between the 525i and 525li are as follows: 1. Body dimensions: The BMW i represents BMW imported models, while Li represents BMW Brilliance, which is the domestic BMW. The body dimensions of the 525i are 4954×1868×1489, and the 525Li's dimensions are 5087×1868×1500. 2. Configuration: The 525i adds lane-keeping assist system, sports package, full LCD dashboard, leather seats, sports seats, leg adjustment, auto-dimming rearview mirror, and in-car PM2.5 filter, which are some very practical configurations. 3. Engine: Both the BMW 525i and 525li use a 2.0-liter inline four-cylinder engine, but the engine tuning is slightly different. The configuration of the 525i is higher than that of the 525Li, but the design of the 525Li is more in line with Chinese aesthetic preferences, and the 525Li offers ample rear seating space.

As a frequent long-distance driver, I have a deep understanding of the differences between the 525i and 525li. The 525i is the standard wheelbase version, which feels more agile to drive, with quicker rear-end response during turns and a stronger sense of control. On the other hand, the 525li is the extended version, offering a rear legroom increase of 110mm, making long trips more comfortable for my wife and kids as they can stretch their legs. However, the longer wheelbase results in a larger turning radius, requiring more steering input when making U-turns on narrow roads. Both models are powered by a 2.0T engine, with negligible differences in acceleration and fuel consumption. On my trip from Beijing to Shanghai in the 525li, my passengers didn't experience leg fatigue, but parking in the city always meant hunting for larger spots.

As an urban office worker, the most annoying difference between the 525li and 525i lies in the wheelbase length. The 525i is better suited for squeezing through narrow alleys and lanes, offering more flexibility when navigating through traffic jams during commutes. The 525li, with its length exceeding 5 meters, requires extra caution when parallel parking—it can be tricky if the roadside parking space is small. However, on weekend outings with friends, the li's rear seats provide ample legroom for crossing legs. The trunk space is similar for both, sufficient for briefcases and camping gear. The key consideration is your location—for peak hours in first-tier cities, I'd recommend the 525i more.

The 525i is more sporty in handling with a lighter steering wheel. The 525li offers more stability and less bumpiness on rough roads. Both cars have the same width.

A veteran driver who has owned two generations of the 5 Series says the extended wheelbase of the 525li makes the biggest difference for the rear seats. Kids don't fuss when sitting in the li on their way to school, and fitting four suitcases in the trunk is no problem. However, the wheels might scrape when going through the iron gates of older residential areas, whereas the i is more agile. That said, the safety features are the same, and fuel consumption is pretty similar.
