The cold, damp surface of MIRA’s horizontal mile straights served to prove two points: that a pair of driven axles is infinitely better than just the one when it comes to deploying immense power to the road in less-than-ideal conditions, and that the C63 S Coupé is a devastatingly quick car once it finds its footing.
Of course, Mercedes’ quoted 503bhp and 516lb ft mean neither of those observations comes as much of a surprise. However, the fact that this most junior member of Mercedes-AMG’s V8 line-up felt as though it would happily continue to accelerate long after it had punched through the Armco that bookends MIRA’s track is telling. With the optional AMG Driver’s Package, top speed is capped at 180mph rather than 155mph, although we’d not bet against the C63 S nudging 200mph if freed from its electronic constraints.
More objectively, with two testers aboard the C63 S recorded a two-way average 0-60mph time of 4.3sec – 0.4sec shy of Mercedes-AMG’s claimed time. In these conditions, however, traction in the lower gears was a precious commodity, and a dry surface would undoubtedly see that time tumble. Indeed, even in the damp, the 100mph marker was surpassed at 9.2sec, putting the C63 S on a par with the identically powerful Giulia Quadrifoglio, and a mere 0.4sec behind the M4. Given that both of those rivals were tested on a bone-dry day, AMG can hold its head up high.
