BMW has at long last nailed the M4 recipe with the CS. Early M4s felt wayward and approximately controlled at the back pivot which, joined with a deficiency of footing, made them spiky and nerve-wracking to drive.
Each resulting adaptation has showed signs of improvement, none more so than the CS, which is considerably more a cut-value GTS than an uprated Competion Package.
The CS has the finest-judged body of any BMW M auto underway. It’s wildly accelerative, more pleasant inside than any M4 before it, and not very hardened to live with. A Competition Package does a significant part of the same, obviously, yet it’s the CS’s frame, grasp and footing that makes it the best M4, as well as M’s best driver’s auto, as well.
