With the F40 in 2019 the 1 Series moved to front-wheel drive and the UKL2 platform shared with MINI, the X1 and the 2 Series Active Tourer. The break with the F20 is total: different drive layout, different platform, a transverse engine — and appreciably more rear legroom, which was the point of the exercise.
So practically nothing from an F20 fits. Start with the UKL relatives rather than the old 1 Series. The range topped out with the M135i xDrive, a two-litre turbo with 306 hp, which brings its own bumpers and tailpipes but shares doors, wings, bonnet and tailgate with an ordinary F40.
In 2024 the F40 was lightly reworked as the F70 arrived. The body stayed, the lamps changed, so for front-end parts the year settles it.
The model is not old enough to be broken in numbers yet; switches, ignition barrels and the odd panel are what reaches us.
