How many cylinders does the BMW 320 have?
3 Answers
BMW 320 is equipped with a four-cylinder engine, which can also be called a four-cylinder engine. It is a machine that can convert one form of energy into another more useful form of energy. Its body is mainly composed of cylinder block, crankcase, cylinder head and cylinder gasket. It is mostly used in car engines, motorcycles, chainsaws and other small power machinery. The BMW 320 model is equipped with a 2.0T turbocharged engine with a maximum power of 115kw, a maximum torque of 250nm, a maximum power speed of 6400rpm, and is matched with an 8-speed manual and automatic transmission.
I've always been quite interested in the BMW 3 Series, and the 320 model has indeed had different configurations throughout its history. The older E90 generation 320i used a 2.0-liter inline-six naturally aspirated engine, which delivered exceptionally smooth driving. However, after the 2012 F30 generation update, it switched entirely to turbocharging, primarily featuring the 2.0T four-cylinder N20 engine, which was later upgraded to the B48 model. The latest G20/G28 generation 320i still maintains the four-cylinder layout. Although it has fewer cylinders than the older models, its 184 horsepower is more than sufficient, and fuel efficiency is even better. I test-drove the current model, and the turbo kick-in when flooring the accelerator is quite noticeable, making it perfectly suitable for daily commuting. The engine noise is also better controlled compared to the older models. When buying used, pay attention to distinguishing between generations, as the engine differences are quite significant.
From a technological evolution perspective, the BMW 320 has undergone significant transformations. The 2005-2011 models were equipped with the N46 series four-cylinder engines, the 2012-2015 models upgraded to the N20 four-cylinder turbocharged engines, and since 2016, they have been powered by the B48 modular four-cylinder engines. Currently, all the 320Li/320i models on the road feature a four-cylinder structure, delivering a maximum torque of 270 Nm at just 1350 rpm. The most notable improvement is the B48 engine's adoption of a water-cooled intercooler, with shorter intake piping, resulting in significantly faster power response compared to older models. The modular design enhances parts commonality, reducing long-term maintenance costs. While the classic straight-six naturally aspirated engines were iconic, today's four-cylinder turbocharged engines outperform them in both performance and efficiency, easily surpassing 220 horsepower with a simple stage 1 tune.
