If the standard M4 is not quick enough for you, but the track focused GTS is too hardcore, then welcome to the 2017 M4 CS, the best of both worlds?
The CS takes BMW's M4 'Competition Pack' and moves the game on a little further. The CS inherits the GTS' carbon fibre bonnet, 20 inch alloys and sticky Michelin Sport Cup 2 tyres. Additional carbon fibre skirts and splitters help shed over 70 lbs from the base M4's kerb weight.
Although visually similar to the base model, the CS interior has a sportier feel, while retaining the quality and usability of a daily driver.
Sitting between the £57k 425bhp standard M4 and the £121k 493bhp no compromise GTS, the 454bhp CS comes in at a hefty £89k in the UK.
So, should the CS be considered a cut price GTS with all the usability o the standard M4, or is it unworthy of the extra £32k demanded by BMW over the base M4? Perhaps the real winner would be a standard M4 with the competition pack?
