What is the displacement of the BMW 325?

325i has a 2.5-liter displacement, with only the 2011 BMW 325i Convertible Coupe version featuring a 3.0-liter displacement. Below are the relevant details: 1. Detail Modifications: The BMW 325i, as a minor facelift of the new 3 Series, is somewhat conservative, but the changes in details are generally successful. The inline 6-cylinder 2.5L engine is mature in technology and operates stably. The craftsmanship and materials are impeccable, with no significant changes in styling, and the i-Drive system has been further improved. The handling level of the 3 Series is widely recognized, offering both fun and safety. Although it has single-piston brakes, the braking force is sufficient with the help of electronic assistance systems. The chassis is sturdy, and the car performs very solidly at high speeds. 2. Power: The new 325i still uses BMW's most classic inline 6-cylinder engine, with improved response speed and power explosiveness compared to before. It delivers a maximum power of 160 kW (218 hp) and a maximum torque of 250 Nm, equipped with Valvetronic variable valve technology. The power starts to surge from around 2,500 rpm and continues up to approximately 6,000 rpm. Acceleration performance has been tested, achieving 0-100 km/h in under 8 seconds, and the sound of the engine during full acceleration is exhilarating.

I remember the displacement of the BMW 325 has varied over different eras. The early classic models, like the E36 and E46 series from the 1990s, all used a 2.5-liter inline-six engine, and that naturally aspirated power delivery was exceptionally smooth. Later, with the E90 generation, BMW changed the 325's displacement to 3.0 liters, but it was still called the 325 model, which was quite confusing. For newer models like the G20 BMW 3 Series, the 325 in the Chinese market uses a 2.0-liter four-cylinder turbocharged engine. Overall, the 2.5-liter engine is what old fans recognize as the standard, but when buying a car, it's best to check the specific year and engine model to avoid misunderstandings. Nowadays, some new owners aren’t familiar with the history and assume all 325 models have large displacements, but it’s important to check the configuration sheet based on the specific market.

As an owner who has driven several generations of BMWs, I've personally experienced the evolution of the 325's displacement. Back when I drove the E46, that 2.5L inline-six engine had such character—smooth acceleration without being abrupt. When I switched to the new G20 325Li, I noticed the displacement dropped to a 2.0T, but with the turbo, it's actually more fuel-efficient and perfectly adequate for city driving. I believe displacement isn't everything; tuning and driving feel matter more. BMW's 2.5L is a nostalgic choice, ideal for enthusiasts who love linear power delivery, while the 2.0T is better suited for daily commutes—fuel-efficient and practical. If you come across a 325 in the used car market, remember to check the model year—older and newer models drive quite differently.

Regarding the displacement of the BMW 325, it has undergone multiple evolutions. The original E30 and E36 models featured a 2.5-liter six-cylinder engine, known for being classic and reliable. Later, during the E90 era, it was upgraded to a 3.0-liter engine while retaining the 325 designation. The latest model now utilizes a 2.0T four-cylinder engine. These changes reflect tightening emissions policies, forcing engineers to adjust their strategies. However, the core sporty DNA remains unchanged – horsepower specifications are a more practical indicator. We recommend owners not focus solely on displacement numbers.
