The BMW 1 Series has three chassis codes: F20 for the five-door hatchback, F21 for the three-door hatchback, and F52 for the domestic sedan version. Here is an introduction to the BMW 1 Series: 1. The 1 Series is equipped with four engines: a 1.5-liter turbocharged engine, a low-power version of the 2.0-liter turbocharged engine, a high-power version of the 2.0-liter turbocharged engine, and a 3.0-liter inline six-cylinder turbocharged engine. 3. The 1.5-liter turbocharged engine has a maximum power of 100 kW, a maximum torque of 220 Nm, a maximum power speed of 4400 rpm, and a maximum torque speed range of 1250 to 4300 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. 4. The low-power version of the 2.0-liter turbocharged engine has a maximum power of 135 kW, a maximum torque of 270 Nm, a maximum power speed of 5000 rpm, and a maximum torque speed range of 1350 to 4600 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. 5. The high-power version of the 2.0-liter turbocharged engine has a maximum power of 165 kW, a maximum torque of 310 Nm, a maximum power speed range of 5200 to 6500 rpm, and a maximum torque speed range of 1400 to 5000 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. 6. The 3.0-liter turbocharged engine has a maximum power of 250 kW, a maximum torque of 500 Nm, a maximum power speed of 5500 rpm, and a maximum torque speed range of 1520 to 4500 rpm.

As a car enthusiast, I know the chassis codes for the BMW 1 Series vary by generation. The first-gen 1 Series, roughly the 2004 to 2013 hatchback version, used the E87 chassis code; the second-gen from 2011 to 2019 primarily used F20 and F21; the current third-gen since 2019 mostly uses F40. These codes aren't just numbers—they represent different design and handling characteristics. For example, the E87 emphasized rear-wheel-drive sportiness, the F20 focused on fuel efficiency and practicality, while the F40 shifted to front-wheel-drive for daily adaptability. I've driven the F20 model, and its suspension was tuned quite soft, making it ideal for city driving. The evolution of chassis codes reflects BMW's shift from pure performance to comfort. For buyers, checking the model year helps avoid missing key details. Maintenance is simpler too—just remember to verify the code to prevent buying wrong parts.
