Overview

2018 BMW M5

The 2018 BMW M5, codenamed F90, represents a significant leap in performance and technology for the M5 lineage. It pairs a potent 4.4-liter twin-turbo V8 engine with an eight-speed M Steptronic automatic transmission and a sophisticated all-wheel-drive system, delivering supercar-like acceleration. While its performance credentials are undeniable, used buyers must be aware of its early-life technical bulletins and recalls, particularly those affecting the fuel system and engine control software. The absence of owner complaints in NHTSA data is a positive sign, but the concentration of recalls in critical areas warrants careful inspection.
