2015 Mercedes-AMG C63 S – Should Audi Be Scared?

Some say that there’s no replacement for displacement. Mercedes-Benz certainly seems to think so, and Audi might start getting nervous about it. The upcoming Audi RS4 should be getting somewhere in the ballpark of 450 hp, from a twin-turbocharged V6 engine, but it still might not be enough to match the C63 AMG S’ 503 ponies from its 4.0 liter twin-turbocharged V8.

The Mercedes-AMG C63 S is a violent thing. With 503 hp and 516 lb-ft of twist all sent to the rear wheels, the C63 AMG is a monster purpose built to shred tires. But don’t think that it’s just a big brute with no real world performance. This monster can nail 60 mph from a standstill in 4 seconds flat and runs a 12.2 quarter mile. That’s quick. It’s also a handler too, something that previous AMGs weren’t always known for. According to a recent drive review by Motor Trend, the C63 was successfully chasing down a BMW M3 through twisty canyon roads and, according to the folks at MT, the C63 was right up there with the M3 in terms of handling.

The upcoming Audi RS4 is going to be a significant upgrade over the outgoing model. It will be built on a new chassis, have new suspension geometry, a far better engine and a better gearbox. But will it be enough for the C63, or even the BMW M3? Well, the RS4 will be more powerful than the M3, but down on power from the C63. However, being that one of its two turbochargers will be electrically driven, it should have instantaneous torque delivery, effectively eliminating turbo lag. Plus it’s the only one of the bunch to have all-wheel drive. So it should be able to put its power down better than both. And considering the new platform and Audi’s extensive weight loss program, the RS4 should definitely be lighter than the Benz, and probably equal to the BMW.


In terms of looks and interior, the Audi will most likely have a better interior than the M3, which is more function than form, but it will be hard to beat the C63. Mercedes has been on an absolute role, in terms of design, and the C63 AMG is no different. The exterior is cool and collected, like a professional hitman. But the interior is a gorgeous example of sporty luxury. With wonderful materials everywhere and a gorgeous design, Audi will be hardpressed to beat it. The RS4 will likely look like the best iteration of the A4, but considering how safe Audi played the new A4’s design, it’s likely that the RS4 won’t be the most exciting car in its class. However, the Audi will most certainly get close to the C63 in terms of interior. It’s tough to beat, but the new A4’s interior is a lovely place and filled with Audi’s latest technology. The RS4 should be no different, except for some sportier materials and better seats. So the interior battle will be close.

It’s nigh impossible to actually determine which car will be better without driving them, especially given how little we know about the upcoming Audi RS4. However, seeing the Mercedes-AMG C63 S, it’s safe to say that Audi should start worrying a bit. The BMW M3 is the current segment leader, and a damn good one. So if the Mercedes-AMG C63 S has the ability to possibly dethrone it, then the next RS4 needs to be nothing short of spectacular if it wants to take the throne for itself.

I've been in love with cars since I was a kid, specifically German cars. Now I get to drive them talk about them on the internet.
