Why is the BMW 7 Series called G12?
3 Answers
The chassis code for the BMW 7 Series is G11 and G12, where G11 refers to the standard wheelbase version, and G12 denotes the long wheelbase version. 2.0-liter engine: The 2.0-liter turbocharged engine in the BMW 7 Series delivers a maximum power of 195 kW and a peak torque of 400 Nm. This engine achieves its maximum power at 5,000 to 6,500 rpm and its peak torque at 1,550 to 4,500 rpm. It features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. 3.0-liter turbocharged engine: The 3.0-liter turbocharged engine produces 340 horsepower and a maximum torque of 450 Nm. This engine reaches its peak torque between 1,500 and 5,200 rpm and its maximum power between 5,500 and 6,500 rpm. It also incorporates direct fuel injection technology and employs an aluminum alloy cylinder head and block.
The BMW 7 Series is referred to as the G12 because BMW uses this internal code to designate a specific generation of the model. Each generation of BMW has its own unique chassis code; for example, the previous generation 7 Series was called the F01, and the one before that was the E65. G12 specifically denotes the long-wheelbase version of the sixth-generation 7 Series. BMW employs this naming convention to help engineers easily distinguish between different models during development and production. I find this naming system quite practical, given the complexity of BMW's product lineup—without these codes, it would be easy to confuse the various models. The G12 generation was produced from 2015 to 2022 and included not only conventional powertrains but also hybrid versions. This coding practice is common in the automotive industry; for instance, the Porsche 911 uses the 992 code, and the Mercedes-Benz S-Class is designated as the W223.
Did you know that BMW models all have internal codes? G12 is the identity of the sixth-generation 7 Series long-wheelbase version. BMW started using this alphanumeric combination to name new cars back in the 1940s, beginning with the 'E' prefix, later switching to the 'F' series, and now using 'G' as the latest prefix. I think this method is really efficient—designers can just mark 'G12' on the blueprint, and the workshop workers immediately know which parts to use. This generation of the 7 Series is quite interesting: the standard version is called G11, while the extended version is G12, lengthened by about 14 cm. The code also reveals the model year—this generation launched in 2015 wasn't replaced until last year by the new 7 Series. These codes are especially popular among BMW enthusiasts. Veteran fans often talk about how to modify the G12, which rolls off the tongue much easier than saying '2018 730Li.'
