BMW M3 and Mercedes-AMG C63

Our verdict

If you’re in the market for the fastest and most capable saloon out there, you should opt for the BMW M3. It outperforms the Mercedes-AMG C63, both in a straight line and around corners.

That said, it’s only when driven to its limits that the M3 really comes alive. If you’re looking for something a little more laid-back and charismatic, then you may find the C63 the more appealing of these two rampant saloons.
