4 Answers
BMW 320li and 325li differ mainly in their engines, but there are also significant gaps in wheel rims, interior, and safety configurations. The main differences are as follows: 1. Engine: The 320li has a 4-cylinder engine, while the 325li has a 6-cylinder engine. The 320li's engine is an improved version of the previous generation E46 318i engine, whereas the 325li features the new magnesium-aluminum alloy engine from the E90 series. 2. Brake discs: The 320li has front 292 and rear 296 brake discs, while the 325li has front 300 and rear 300 brake discs. 3. Wheel rims and tires: The 320li comes with 16-inch rims and 205 tires, while the 325li has 17-inch rims and 225 tires. Although both use run-flat tires, the Continental run-flat tires on the 320li are of a lower grade compared to those on the 325li, with differences not just in width. 4. Interior: The 320li has a standard steering wheel, while the 325li features a sport steering wheel. Except for the top trim of the 320li, the audio system is downgraded, including the amplifier, whereas the 325li is equipped with HARMAN/BECKER mid-range audio system across all trims. 5. Safety: The 320li has a cruise control system, while the 325li features a dynamic cruise control system. The 320li's DSC dynamic stability system is the same as the older 318i's, whereas the 325li comes with the truly new-generation DSC advanced dynamic stability system.
When it comes to the differences between the BMW 320Li and 325Li, I was torn between them when buying a car. The 320Li is more affordable, suitable for daily commuting, with around 180 horsepower and slightly lower fuel consumption, making it steady for city driving. The 325Li, on the other hand, has over 200 horsepower, offering stronger acceleration and a more thrilling experience when overtaking, but it costs tens of thousands more and has slightly higher fuel expenses. Both cars look similar in appearance and interior, featuring a long wheelbase with spacious rear seats, ideal for family passengers. However, the 325Li comes with more luxurious configurations, such as a better sound system and more intelligent features. If you're on a budget, the 320Li is sufficient, while the 325Li is the top choice for those who prioritize driving pleasure. The choice depends on your needs: go for the 320Li for practicality and savings, or the 325Li if you love speed.
I've been driving BMWs for many years and have test-driven both the 320Li and 325Li, so I'm quite qualified to comment. The 320Li's engine output is conservative, with smooth starts, making it economical for daily commutes, with fuel consumption around 7 liters—perfect for congested cities. The 325Li has stronger power, delivering a thrilling push-back feeling when revved up, accelerating faster than the 320Li and offering more stable handling on highways, though the engine noise is slightly louder, and fuel consumption jumps above 8 liters. In terms of price, the 325Li costs about 30,000 to 40,000 yuan more, possibly adding features like keyless entry or a larger screen. The space is the same, with the Li version's extended wheelbase making it great for family trips. Maintenance costs are slightly lower for the 320Li, with less frequent tire and oil changes. If you prioritize driving and don’t mind spending extra for enjoyment, the 325Li is worth it—otherwise, the 320Li is a solid choice.
The core difference between the BMW 320Li and 325Li lies in engine tuning. Both are equipped with a 2.0T four-cylinder engine, but the 320Li delivers around 184 horsepower with lower torque settings, offering a smooth and fuel-efficient ride. The 325Li, on the other hand, boasts 218 horsepower with optimized turbocharging, achieving peak torque earlier for more responsive acceleration during quick maneuvers. Both models feature the same 8-speed automatic transmission, but the electronic control systems differ, making the 325Li more responsive. The chassis and suspension tuning are similar, with the Li versions offering extended rear seats for added comfort. However, the 325Li includes optional driving modes or advanced assistance systems. Priced a few ten thousand higher, the 325Li suits those seeking performance. Overall, engine output is the primary dividing line.
