3 Series long-wheelbase version bears the 'Li' badge at the rear, while the standard-wheelbase models carry the 'i' badge. The BMW 320, 325, and 330 are all available in both long-wheelbase and standard-wheelbase configurations. The BMW 3 Series is a sporty B-segment sedan under the BMW brand, equipped with three engine options: a low-power 2.0-liter turbocharged engine, a medium-power 2.0-liter turbocharged engine, and a high-power 2.0-liter turbocharged engine. The low-power 2.0-liter turbocharged engine delivers a maximum power of 115 kW and a peak torque of 250 Nm, with maximum power achieved between 4,500 and 6,500 rpm and maximum torque available from 1,250 to 4,000 rpm. It features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block.

To be honest, I drive the 3 Series long-wheelbase version mainly for its spacious rear seats, typically models like the 320Li or 330Li. The 'Li' stands for long-wheelbase. This version, specifically tailored for the Chinese market, stretches the original 3 Series wheelbase from around 2850mm to 2920mm, offering significantly more legroom—perfect for someone like me who frequently takes friends on long trips. In terms of driving experience, it still features the familiar 2.0T B48 engine, with slightly softer handling but noticeably improved comfort. However, you do need to be more cautious about positioning when parking or turning due to the extended length. The most common generation now is the G20, starting at around 400,000 RMB, with a variety of configurations available, ranging from luxury to M Sport packages. The main selling point is the generous rear space. Maintenance costs haven’t seen any significant increase either—the dealership says the extended part doesn’t require extra effort to repair. If you often drive in congested urban areas or take frequent family trips, this version is definitely a solid choice.

As a car enthusiast, I notice that the 3 Series long-wheelbase version mainly includes the G20 or late-generation F35 Li models, such as the 330Li. With the extended wheelbase reaching around 2920mm, it offers several dozen millimeters more space than the standard version. BMW introduced this specifically to cater to the Chinese market, as Chinese users prioritize rear-seat comfort. Therefore, designers deliberately extended the wheelbase without modifying the powertrain, keeping engines like the B48 series output unchanged. There's a slight loss in agility for handling, but it wins in practicality. Looking back, the lengthening trend started during the F30 era, and now the new version even supports M Sport package combinations, with smooth driving mode transitions. This version is rare in global markets, primarily sold in Asia, making it quite unique. Fuel consumption increases slightly by a few liters, but on long trips, rear passengers praise its comfort as worth the trade-off. Don’t expect track-level handling—it’s rock-solid for family commuting.

When taking kids out, the 3 Series Long Wheelbase is my top choice, with the 320Li model being the most practical option. The rear seats are significantly more spacious, with the wheelbase extending from the standard 2900mm to 2920mm, providing ample room for child safety seats without feeling cramped, and there's still space for luggage. BMW designed this specifically to meet the needs of Chinese families. It's slightly more expensive than the short-wheelbase version, but it's worth it. The drive is smooth, with quick engine response, making it ideal for city commuting. Just remember it's a bit longer when parking. Daily maintenance is no different, and replacing parts isn't a hassle. Overall, it's a thoughtful upgrade, with rear seat space that liberates your legs, perfect for long trips.

Considering the 3 Series Long Wheelbase version, I checked models like the 330Li, with a wheelbase of 2920mm, offering over 100mm more space than the standard version. During the test drive, the rear seating area felt genuinely spacious, comfortably accommodating passengers or bags without feeling cramped. However, there was a slight sense of sluggishness when cornering, though the engine delivers the same efficient B48 performance. Pricing varies by configuration: the base 330Li starts at 320,000 RMB, while the high-end version with a luxury package goes up to 450,000 RMB. The main appeal lies in its spacious advantage and decent driving experience, making it suitable for city driving and family trips. The downside is a bit less agility, but it offers good value for money with no significant increase in maintenance costs. The M Sport version Li also offers a sportier style option.

Having repaired cars for many years, the 3 Series long-wheelbase version is commonly known as the Li model, such as the 325Li. The chassis has an extended wheelbase of 100-110mm while maintaining the original mechanical structure. During repairs, replacing the rear suspension is easier due to the ample space. The engine remains unchanged, so maintenance costs stay the same. This model primarily caters to Asians' preference for larger space, with the Chinese market being its main consumer. New owners often report that the rear seats are comfortable and practical, the car drives stably, and the slightly higher fuel consumption is negligible.
