The 40% larger front kidney grille of the 2019 BMW 7 Series facelift caused some controversy among customers and was not taken too well. According to the designer, however, there were 2 main reasons for the grille to be of this size. One is that, since this was the largest 7 Series sedan so far, the grill needed to be in proportion to where the vehicle stands in the range. The other reason has to do with the lower bumper. Thanks to the grille being styled this way, the lower bumper was able to have a more clean design, which therefore helps aerodynamics.
BMW 7 series is a range of full-size luxury sedans, so yes, they can be considered large vehicles, with Long Wheelbase variants reaching up to 5260 mm (207.09 in.) in length.
In short, yes. BMW 7 Series luxury sedans do require more expensive parts and maintenance, and according to owners, often need repairs. Performance, however, which these cars were built for, is exceptional.
