BMW does not appear to have officially marketed a model called 750Lxi. The closest and historically correct BMW nameplate is 750Li xDrive, a long-wheelbase, all-wheel-drive variant of the 7 Series. BMW’s naming conventions place the xDrive badge after the main model designation, so the official form is 750Li xDrive rather than 750Lxi.
The 750Li xDrive first appeared for the 2010 model year, when BMW added xDrive to the 7 Series flagship sedan line. In BMW’s internal and press materials, the model was introduced as the all-wheel-drive partner to the 750Li, bringing the long-wheelbase 7 Series format together with the brand’s xDrive system. That combination established the car as the more comfort-oriented, chauffeur-friendly V8 flagship in the 7 Series range.
BMW continued the 750Li xDrive through the sixth-generation 7 Series, including the G12 long-wheelbase era launched for the 2016 model year and later facelifted versions. During that period, it remained one of the upper mainstream gasoline offerings in the lineup, positioned below the V12-powered M760Li xDrive and above the six-cylinder variants. It was also used for special editions and market-specific luxury versions, reinforcing its role as the high-end long-wheelbase V8 7 Series.
The nameplate appears to have ended with the previous 7 Series generation before BMW moved to the seventh-generation G70 lineup, which introduced different flagship designations such as 740i, 760i xDrive, and 750e xDrive instead of 750Li xDrive. Because BMW’s official materials do not consistently present a separate marketed nameplate called 750Lxi, and the exact final model year is not fully clear from the available sources, the safest historical classification is the official 750Li xDrive nameplate, first offered for the 2010 model year.
