li and i have the following differences: 1. Different wheelbase: The BMW li series are models with an extended wheelbase, while the BMW i models have a standard wheelbase. Simply put, the wheelbase is the distance from the center of the front wheel to the center of the rear wheel on the same side, which affects the length of the car. 2. Different levels: For cars, the longer the wheelbase, the higher the car's level. That is to say, generally, the BMW li has a higher level than the BMW i. 3. Different comfort levels: Because the wheelbase of the li series is longer than that of the i series, the li series cars are more comfortable to ride in than the i series cars.

When I first switched to , I specifically researched this difference. Simply put, Li is the long-wheelbase version, while i is the standard-wheelbase version. The Li has a longer body, offering particularly spacious rear seating—enough to stretch your legs—making it very comfortable for family outings. However, the longer body makes it less agile in turns and feels a bit heavier in city driving. The i version, with its shorter body, provides more nimble handling, which is great for solo driving. Additionally, the Li is more expensive, with a price difference of tens of thousands for the same model. I think the choice depends on your needs: if you frequently chauffeur clients or carry multiple passengers, the Li is the way to go, but if you drive alone most of the time, the i version is sufficient.

As someone who has been driving for over a decade, I pay special attention to wheelbase. The Li extended version is indeed more comfortable to sit in, especially with much less bumpiness when going over speed bumps. However, the standard wheelbase i version is the one that really delivers excitement when driving, feeling particularly stable when taking corners. Although the Li version comes with higher configurations, it also has slightly higher fuel consumption, making long-term ownership a bit more burdensome. When I was buying the car, the salesperson told me that more people in southern cities opt for the standard wheelbase version, while the long wheelbase version seems to be preferred in the north, possibly due to road conditions. Personally, I feel that the i version drives more like the authentic BMW experience, while the Li version focuses more on comfort.

A friend of mine who works at a 4S store explained this difference to me in detail. The Li version's rear door is over 10 cm longer than the i version, and the entire vehicle is just that much longer. This extra space is mainly allocated to the rear seats, providing about a fist's more distance between the knees and the front seats. However, the trunk space is roughly the same. I've tried both models - the standard wheelbase version feels more responsive with sharper steering and quicker acceleration. The long wheelbase version shows slightly delayed body response when cornering. Price-wise, the Li version costs 20,000-30,000 RMB more, with slightly higher maintenance and tire replacement costs in the long run.

Once when I was getting my car repaired, I chatted with the veteran mechanic about this. He gave me a simple way to tell the difference: look at the position of the door frame—the Li version has a section further back than the i version. This extra space mainly provides more comfort for rear passengers. However, the longer body increases the turning radius, so you need to be careful when making U-turns on narrow roads. The standard wheelbase version has a natural advantage in handling, with much more direct steering response. If you enjoy weekend drives on mountain roads, I’d recommend the i version without hesitation. The long wheelbase is more suitable for business use or families with elderly or young children.

During the auto show, I specifically compared the 5 Series i and Li versions. The long-wheelbase Li version offers a truly luxurious rear seating experience with ample legroom and electrically adjustable seats. Although the standard-wheelbase i version has slightly less space, it's about a hundred kilograms lighter, making acceleration and overtaking particularly crisp. The on-site salesperson told me that younger buyers tend to opt for the standard-wheelbase version, while those over forty mostly choose the long-wheelbase model. From a design perspective, the standard-wheelbase version has more balanced proportions and a stronger sporty feel, whereas the long-wheelbase version exudes a more stable and grand presence. In terms of fuel consumption, the i version saves a bit more in city driving, averaging about a few tenths of a liter less.
