The differences between 320 and 325 are as follows: 1. Significant power gap: The 320i has 156 horsepower, 250N·m torque, and accelerates from 0-100km/h in 9 seconds. The 325i has 186 horsepower, 300N·m torque, and accelerates from 0-100km/h in 7.3 seconds. 2. Fewer non-essential configurations: Compared to the 325i, the 320i lacks the M sport steering wheel, Sensatec synthetic leather dashboard, intelligent induction ambient lighting (including welcome light carpet), professional connectivity suite (including remote services, real-time traffic information, extended BMW Intelligent Personal Assistant, etc.), cruise control system with braking function, and fewer paint color options (missing Carbon Black and Portimao Blue). Both models have 18-inch wheels, but with different styles, and the 320i comes with a black interior. 3. Reduced configuration gap: Compared to the 325Li, the 320Li still lacks intelligent induction ambient lighting (including welcome light carpet), professional connectivity suite (including remote services, real-time traffic information, extended BMW Intelligent Personal Assistant, etc.), and cruise control system with braking function.

I've driven both cars many times. The 320 and 325 look quite similar in appearance, but there's a significant difference in power. The 320's 2.0T engine only delivers 156 horsepower, making it quite relaxed when starting from traffic lights. The 325 is tuned to 184 horsepower, and you can clearly feel the acceleration when you step on the gas, giving you much more confidence when overtaking. In terms of chassis tuning, the 325 offers better support and less body roll during high-speed cornering. Another detail difference is that the 320 comes with 17-inch wheels while the 325 is equipped with 18-inch ones, with different tire widths, giving the 325 better grip and more stability in rainy conditions. The fuel consumption difference isn't actually that big. Although the 325 has stronger power, its transmission tuning is smarter, resulting in only about half a liter more per 100 kilometers overall. If your budget allows, I'd recommend choosing the 325—the extra cost for the power upgrade is definitely worth it.

I struggled for a long time choosing between these two models back then. The 320 is about 30,000-40,000 yuan cheaper than the 325, but they feel completely different to drive. The 325's power response is so quick it's like driving a different car, especially during 60-100 km/h acceleration - lane changes and overtaking feel particularly crisp. In terms of features, the 325 adds paddle shifters and sport seats, with a slightly heavier steering wheel. The braking systems differ too - the 325 has larger brake discs that maintain stopping power better during continuous downhill driving. There's also a hidden difference in the exhaust system, with the 325 producing a deeper, more resonant sound. In the market, the 325 holds its value slightly better too, so the price difference isn't as big as you might think when you do the math.

Last week, I accompanied a friend to test drive and compare these two models. The most noticeable difference was the moment stepping on the accelerator: the 320 feels like a waking lion, while the 325 charges forward like a leopard. Both are powered by the B48 engine, but the 325 has 28 kW more power and is over a second quicker in 0-100 km/h acceleration. The steering response of the 325 is more precise, especially when navigating consecutive curves—it goes exactly where you point it. The seat materials also differ; the 325's sport seats offer tighter lateral support. The 320 has a semi-digital instrument cluster, whereas the 325 features a full digital display that can even show turbo pressure values. The headlight assemblies are different too—the 325 comes with adaptive headlights that provide a wider illumination range when turning at night.

The repair shop has seen quite a few of these two models. The chassis structure is basically the same, but there are differences in parts. The front suspension springs of the 325 are 15% stiffer, and the rear anti-roll bar is 2mm thicker. The brake calipers on the 325 are dual-piston, providing slower heat fade during continuous braking. The most easily overlooked aspect is the cooling system—the 325's radiator is 18% larger, ensuring more stable water temperatures during aggressive driving. The capacity also differs; the 325 uses a 92Ah AGM battery, which is more durable with start-stop functionality. Tuning enthusiasts prefer the 325, as it can easily surpass 220 horsepower with an ECU remap.

After driving a 325 for five years and having a friend who owns a 320, a long-term comparison revealed several key points. The extra horsepower in the 325 mainly kicks in between 2500-5000 RPM, which might not be noticeable during daily driving but becomes evident when fully loaded with the air conditioning on or climbing hills. The transmission shift logic also differs, with the 325 downshifting more aggressively. The 325 consumes slightly more engine oil, requiring an additional half-liter during . The 325 comes equipped with run-flat tires, which are slightly noisier but offer higher safety. When inspecting a used 325, pay special attention to the common issue of valve cover oil leaks, with repair costs starting at around 2000 RMB. In the long run, the operating costs of the 325 are about 10% higher, but the driving pleasure is absolutely worth the extra expense.
