Hi all. I joined this forum about 18 months ago, alongside the purchase of my first BMW - a CPO 2021 X7 M50i. I have learned a lot from reading the posts. As a BMW newbie, I am sometimes confused by the E, F, G codes that are used when referring to the various vehicle models, as well as the N and S codes used when referring to various engines. I decided to do a little google searching to learn more. From my readings, I believe the following is correct. Can you confirm?

- Each BMW historically carried an E project number – standing for Entwicklung, or development. The numbers rose progressively up to triple digits, at which point F numbers took over, and then G numbers eventually took over.
- E53 = 1st-gen X5, 2000-2006
- E70 = 2nd-gen X5, 2007-2013
- F15 = 3rd-gen X5 2014-2017
- F85 = X5 M, 2015-
- G05 = 4th-gen X5, 2018-present
- G07 = X7, 2019-present
- G09 = XM, 2022-present

- BMW B58 = turbocharged straight-six engine, which began production in 2015. Used in X5 40i and X7 40i.
- BMW N63 = twin-turbocharged petrol V8 engine, in production from 2008-present. 2020-2023; G05 X5 M50i, 2020-2022; G07 X7 M50i
- BMW S63 = BMW M version of the N63, which debuted in the BMW X6 M and was used in the BMW M5 models from 2011 to 2023.
- BMW S68 = twin-turbocharged V8 engine, first use was in the 2022 revised BMW X7 as the M60i.

Pretty much correct. The f95 is the g05 X5 version of the X5M.

F85 X5M - F15 X5
F95 X5M - G05 X5
