Two German titans go head-to-head in the ultimate sports saloon showdown. The BMW M4 Competition brings 503hp from its twin-turbo straight-six, while the Mercedes-AMG C63 S counters with 503hp from a twin-turbo V8.
On track, the M4's lighter weight and sharper steering give it the edge, but the C63 S fights back with its charismatic V8 soundtrack and superior ride comfort.
Both cars offer stunning performance, but your choice will depend on priorities: precision (M4) or character (C63 S).
