What is the chassis code for the BMW 4 Series?

[VonAndrew]

The chassis code for the BMW 4 Series is F32. Here is some information about the BMW 4 Series: 1. The BMW 4 Series is a mid-size car series produced by the German automaker BMW, with three models available: the all-new BMW 4 Series Coupe, the BMW 4 Series Gran Coupe 2020, and the BMW 4 Series Convertible 2019. 2. Model introduction: ① Exterior: Uses a soft-top material that has been popular in convertible history, reducing weight by approximately 40%. ② Interior: The design of the all-new 4 Series Convertible is largely consistent with the hardtop version, featuring a sporty wraparound design and equipped with BMW's latest full LCD instrument panel and iDrive system. ③ Powertrain: The all-new 425i and 430i models are equipped with two different power-tuned 2.0T turbocharged four-cylinder engines, with the former having a maximum power of 135kW and the latter 190kW, both paired with an 8-speed automatic transmission.

I remember the BMW 4 Series chassis codes change depending on the year. The latest second generation, starting from 2020, uses the G22 chassis for the coupe, G23 for the convertible, and G26 for the four-door Gran Coupe. The first generation, from 2013 to 2019, had the F32 for the coupe, F33 for the convertible, and F36 for the Gran Coupe. Chassis codes are super important in car enthusiast circles—each number represents specific platform designs. For example, the G series features a lighter body, significantly improved driving dynamics, and added hybrid support. Knowing these codes helps you quickly distinguish between old and new models, avoid being tricked when buying used cars, or ensure you get the right parts for modifications—like buying suspension kits that won’t be compatible otherwise. I’ve always thought BMW’s coding system is brilliant—it simplifies model discussions and makes communication more precise.

As a long-time BMW owner, chassis codes are quite practical in daily life. My previous generation 4 Series had the F36 chassis, representing the four-door Gran Coupe, while the 2020 new model switched to G22 for coupe, G23 for convertible, and G26 for four-door. Knowing these codes saves a lot of hassle—just quote the code to the mechanic during repairs to ensure correct part matching for items like bulbs or sensors, avoiding misinstallation. Code changes reflect technical upgrades; the G-series suspension tuning is more comfortable, ideal for long-distance driving. In daily use, it helps distinguish body styles, allowing precise discussions about specific versions in car enthusiast groups or when checking maintenance manuals. Overall, memorizing chassis codes enhances the ownership experience by preventing model confusion.

As a technician, chassis codes are essential in the BMW system. Currently, the 4 Series Coupe is coded G22, the Convertible G23, and the Gran Coupe G26; the previous generation from 2013 to 2019 was F32, F33, F36. Each code corresponds to a unique chassis platform, affecting aspects like suspension geometry or electronic control units. When repairing, you must verify the correct code before replacing parts, otherwise components may not be compatible. The new G generation is lighter, which can improve fuel efficiency. In practice, these codes help diagnose issues or select the right tools during maintenance.

I'm interested in automotive history, and the evolution of BMW 4 Series chassis codes is fascinating. The first generation launched in 2013 with F32 Coupe, F33 Convertible, and F36 Gran Coupe models. In 2020, the new generation adopted G22 as the starting code, representing a chassis platform update that reduced weight and enhanced safety. This coding system ensures precise model traceability - when collecting used cars, entering the code allows quick filtering. The G-generation also integrates more driving assistance technologies, improving daily usability.
