There are three chassis codes for the BMW 1 Series: the F20 is the five-door hatchback version, the F21 is the three-door hatchback version, and the F52 is the domestic sedan version. The imported two-door hatchback version of the BMW 1 Series is equipped with four engines: a 1.5-liter turbocharged engine, a low-power 2.0-liter turbocharged engine, a high-power 2.0-liter turbocharged engine, and a 3.0-liter inline six-cylinder turbocharged engine. The headlight assembly of the new BMW 1 Series is smaller compared to the older model and incorporates the iconic LED angel eye design. The rear lights of the new car feature an L-shaped design with integrated LED light strips. The car's dimensions are 4456mm in length, 1803mm in width, and 1446mm in height, with a wheelbase of 2670mm.

The chassis code of the BMW 1 Series is the key identifier to distinguish between different generations, which I remember clearly as a car enthusiast. The first generation was the E87, produced from 2004 to 2011, mainly offering a hatchback version. At that time, it featured rear-wheel drive, delivering a firm and classic driving feel, like a little hot hatch. The second generation had two codes: F20 and F21. The F20 was a five-door hatchback, while the F21 was a three-door version, produced from 2011 to 2019. It drove more balanced and comfortably, with many additional electronic features. The third generation, starting in 2019, uses the F40 code and adopts a front-wheel-drive platform, with a more modern design and significant improvements in fuel efficiency and tech features. Chassis codes are like a car's ID, helping us quickly identify the year and production details—super useful for used car trading or modifications. I often discuss these changes with friends; the F40's handling is more user-friendly, making it especially suitable for daily city commuting.

Can National IV vehicles still be transferred and licensed?

National IV emission standard vehicles cannot be licensed, but those already licensed can still be used. At the same time, used cars with National IV emission standards can be transferred within the same city. Transfers to other regions are mostly acceptable, but in many places such as Beijing, Shanghai, Guangzhou, and some cities in Hebei and Jiangsu provinces, National V emission standards are required for transfer. Since April 1, 2018, the transfer of National IV emission vehicles has been restricted. All coastal provinces do not allow the transfer and licensing of National IV emission standard vehicles: The National Fourth Stage Motor Vehicle Pollutant Emission Standard, referred to as the 'National IV Emission Standard' or 'National IV Standard,' mainly regulates pollutants such as HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter) emitted by vehicles. Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, vehicle pollutant emissions are controlled and reduced to levels below the specified standards. The National 3 and National 4 standards are based on the European 3 and European 4 vehicle emission standards. Compared to National 2, National 3 further reduces pollutant emission limits. The tailpipe pollutant emission limits of China's National 3 standard are 30% lower than those of the National 2 standard, while the National 4 standard will reduce them by an additional 60%. To ensure that vehicles stably meet emission limit requirements during use and maintain the durability of emission control performance, requirements for On-Board Diagnostics (OBD) and in-use compliance have been added.
