The BMW 1 Series F40 marks a historic and controversial turning point for the Bavarian brand: the abandonment of the traditional rear-wheel-drive (RWD) layout and longitudinal engines in favor of the FAAR front-wheel-drive (FWD) architecture with transverse engines.

It offers better rear legroom, a larger trunk, and a massive leap in interior material quality and onboard technology (featuring the excellent iDrive 7.0 system).

The BMW 1 Series F40 is a highly recommended purchase on the used market. While enthusiasts may reject it for abandoning rear-wheel drive, the objective truth is that the F40 is a vastly superior daily driver compared to its predecessor.

Avoid diesels if you only drive in the city to prevent DPF issues.
