The BMW 6 Series has three chassis codes: F06 for the four-door model, F12 for the convertible model, and F13 for the two-door hardtop model. Here is more information about the BMW 6 Series: 1. The BMW 6 Series is equipped with two engines: a 3.0-liter turbocharged engine and a 4.0-liter twin-turbocharged engine. 2. The 3.0-liter turbocharged engine has the code N55B30, with a maximum power of 235 kW, a maximum torque of 450 Nm, a maximum power speed of 5800 rpm, and a maximum torque speed range of 1300 to 4500 rpm. This engine features BMW's Double-VANOS and Valvetronic technologies and uses an aluminum alloy cylinder head and block. It is paired with an 8-speed automatic transmission. 3. The 4.0-liter turbocharged engine is a V8 engine, with a maximum power of 300 kW, a maximum torque of 600 Nm, a maximum power speed of 5500 rpm, and a maximum torque speed range of 1750 to 4500 rpm. This engine also features BMW's Double-VANOS and Valvetronic technologies and uses an aluminum alloy cylinder head and block. It is paired with an 8-speed automatic transmission.

I'm particularly fascinated by BMW's chassis codes, as they're crucial for distinguishing between generations. The BMW 6 Series started with the E24 in 1976 - that iconic shark-nosed classic coupe. When it returned in 2003, it became the E63 coupe and E64 convertible, with those distinctive tail lights. The 2011 generation got more complex: F13 for the coupe, F12 for the convertible, and F06 for the four-door Gran Coupe - all rear-wheel drive models produced on the same assembly line at BMW's Dingolfing plant. The current generation is the G32 launched in 2017, though only as a four-door. With each redesign comes a new chassis code, meaning aftermarket parts must be matched accordingly.

When it comes to the chassis codes of the 6 Series, it's essential to categorize them by body style. For the coupe versions, the first generation produced in 1976 was called the E24, while the second generation revived in 2003 was the E63 coupe. By the third generation in 2011, it became the F13 coupe. As for the convertibles, the second generation carried the E64 code, and the third generation was designated F12. The four-door Gran Coupe is the most unique, with the third generation launched in 2012 named F06, and the current fourth generation being the G32. However, after 2018, BMW restructured its product line, replacing the coupe and convertible models with the 8 Series, leaving only the four-door Gran Coupe in the 6 Series lineup. It's advisable to check the VIN to confirm the chassis code, as it's crucial for maintenance manuals and parts inquiries.

As an old car enthusiast, what I miss most is the first-generation E24. The streamlined design from the 1970s was truly classic. I bought an E63 coupe in 2004 with its compact chassis and precise steering, but the V8 engine was prone to oil leaks. When it was updated to the F-series chassis, BMW began modular production, with the F12 convertible and F13 coupe sharing many components. Now, the new G32 Gran Coupe uses the CLAR platform for lighter weight, but personally, I feel the driving pleasure isn't as good as previous generations. The tuning differences between chassis generations are quite significant, so pay attention to the model year codes when choosing a used car.
