Our verdict

The new BMW M5’s neck-snapping acceleration and ridiculously high handling limits make it the more capable of these incredible performance saloons. If you simply want the faster car, no matter whether the road is straight or winding, it’s the one to buy.

But these are road cars first and foremost, so outright pace is less important than the size of the smile on your face. And the Mercedes-AMG E63 S’s machine-gun V8 soundtrack, more playful handling and similarly staggering straight-line pace make it the more enjoyable and rewarding car. And the fact that you can have it for considerably less money secures it the narrowest of wins.
