The new-look BMW 4 Series will be unveiled today

With an official preview from BMW, it’s expected the bold new grille design is the stand out design feature of the new 4 Series coupe. Its reveal is sure to spark a lively design debate of the sort last seen in the Bangle era with the then controversially styled 7 Series. However, it is thought the upright new grille will not be applied across the board but remain for specialist sporting models like the new coupe.

Another surprise in store for the 4 Series may be its dynamic repertoire, as GRR as previously reported. BMW is keen to position the two-door 3 Series as a far sportier model than before, saying it will have “a chassis set-up focused unerringly on exhilarating dynamic performance”. The range will be headed by a second-generation M4 with around 500 horsepower.

We’ll know more about the new Four when it is unveiled tomorrow (Tuesday).
