Today I had the pleasure to get some hands on time with the G12 2016 750Li and some fellow 7 Series owners brought their rides out to help put together a video showing the evolution of the 7 Series from the E38 > E65 > F02 > G12.

Huge difference between all the generations, but the largest from the E65 to the F02.
