What is the displacement of the BMW 5 Series?
3 Answers
The displacement of the BMW 5 Series 525 is 2.0 liters. Below is a detailed introduction to the golden displacement and the classification of car displacements: Golden Displacement: It features fuel economy, good handling, power, and comfort. It can meet various usage scenarios for consumers, such as business, commuting, travel, etc. In other words, it can maximally satisfy the diverse needs of consumers for vehicle use while maintaining a reasonable price range, hence referred to as the golden displacement or golden model. Car Displacement Classification: In China, the classification of passenger cars is determined by displacement size. Mini cars have a displacement of ≤1.0L. Compact cars have a displacement ranging from 1.0L to 1.6L. Mid-size cars have a displacement ranging from 1.6L to 2.5L. Executive cars have a displacement ranging from 2.5L to 4.0L. Luxury cars have a displacement exceeding 4.0L.
I've researched the displacement of several generations of the BMW 5 Series. The classic models were mostly equipped with 2.0T and 3.0T engines. Currently, the domestically produced long-wheelbase 530Li on sale uses the high-power B48 series 2.0T engine with an actual displacement of 1998cc, while the imported standard-wheelbase 540i is equipped with a B58 inline-six 3.0T engine with a displacement of 2998cc. Earlier imported models had 2.5L inline-six naturally aspirated (N52B25) and 3.0L naturally aspirated (N52B30) engines with displacements of 2497cc and 2996cc respectively. Although the plug-in hybrid 535Le is also called a 2.0T, with the addition of an electric motor, its combined output reaches nearly 300 horsepower while achieving an ultra-low fuel consumption of just 1.8L. Recently, I noticed that in the used car market, there are older 523Li models with 2.5L naturally aspirated engines - these have simpler mechanical structures but higher fuel consumption. It's important to note that BMW's tail badge numbers don't always correspond exactly to the actual displacement, which is something to pay special attention to when buying a used car.
I previously drove my friend's 2023 530Li. This generation of the 5 Series mainly features a 2.0T four-cylinder turbocharged engine, with a mainstream displacement of 2.0 liters. In fact, the 520 and 525 models share the same displacement but with different tuning. Once at a track day event, I had the chance to experience the imported 540i, whose 3.0T six-cylinder engine produces an exceptionally deep exhaust note. I remember the E60 5 Series from over a decade ago even had a 4.0L V8-powered 550i, which is rarely seen nowadays. The current hybrid 535Le, despite its smaller displacement, accelerates very quickly with electric motor assistance and doesn't use any fuel in the city when fully charged. If you're looking for a used one, it's advisable to bring along someone knowledgeable about cars to avoid purchasing a modified vehicle with a tampered ECU masquerading as a higher trim.
