The menacing Mercedes-Benz C63 AMG coupe is slowly making its way into dealerships, ready to eat the souls of any driver willing to tame the 451-horsepower super coupe. It's a hardcore two-door with a naturally aspirated V8 powerplant under the hood, and in our recent stint behind the wheel, we fell head-over-heels in love.

But the C63 isn't the only hot super coupe on the block. The Audi RS5 – a model that will soon be available Stateside – offers 444 horsepower but puts that grunt to the ground via all-wheel drive. It's not as outright vicious as the Merc, but it's certainly capable of standing toe-to-toe, particularly on wet tarmac.

That in mind, the folks at Fifth Gear took these two coupes to the Cadwell Park circuit in Lincolnshire, Great Britain to see which German could pull off the quickest lap time. We won't spoil it for you, so follow the jump and watch Tiff Needell and company have a bit of high-horsepower fun.

      Yes, I do like the Audi a little more than the Merc, so I am biased, but to those that say this is not a good test because the track is wet: Have you ever been to England? You do realize it rains there A LOT! If you are reviewing cars, should you simply ignore common weather in your area for ideal conditions? I mean, if you lived in Phoenix, you wouldn't say, "It is too hot today, I think we should postpone our test until its 80 degrees". Not too mention, most racing series do continue if it is raining, Nascar being an obvious exception.

      I would take the M3 over both of them. But between the RS5 and the C63, there is simply no question about it. The RS5 wins outright. It has better performane, better dynamics, better handling, easier to live with, better interior- it just completely murders the RS5. Yet another car from MB that fails to live up to the hype.

        Seriously, JC... Have you ever driven an M3? Have you ever driven the new C63 (with the new AMG MCT Speed Shift Tranny)?? Have you driven them back to back and when you're done doing that, drive them back to back again and again??? I have because I work in the automotive business and I took advantage of my resources to narrow down my choice between an M3 and a C63. My C63 AMG Coupe will arrive in February. We could go back and forth all day long because our opinions are subjective, but I just can't and won't believe that any experienced auto enthusiast would pick an M3 over a C63 for anything other than track duty. Exterior looks, they both are gorgeous. Interior looks, the updated C63 interior for 2012 is phenomenal hands down. Better dynamics and handling? Sure, take the M3 to the track and you've got your edge and only edge (although it's down to a driver's race). Daily commuting with comfort and ergonomics (because 99% of all drivers will never see the track) the MB is the standard. Don't even get me started with how the C63 sounds. It makes the M3 sound like a Prius. I love the M3's engine and they bring a big gun to the fight, but the 6.2 in the AMG is legendary and Mercedes brings a knuke to the fight. I won't argue or comment on the RS5 because I have yet to drive it or experience it and I will not comment until I do. But take it from me, who has driven, tracked, pushed, and punished these 2 cars before I made my choice, the C63 is the more rewarding car for the auto enthusiast that isn't tracking their cars routinely. I await the next generation M3. BMW, if you are listening, you better invest in some torque.

          Just test drive the M3 once, it hands down is more fun to drive and provides a better experience.

          The M3 has been described as a modern legend by enthusiasts. The same cannnot be said for the C63. Almost every comparo I see, the M3 beats the C63.

          JC, can you read? Ghetto2315 has said it perfectly. The AMG products are better suited for daily driving and are easier to live with on a daily basis. Nobody is denying that the M3 is the better track car - so what? Who actually takes these cars unto a track? I got news for you - most of the people buying these cars don't drive competitively. They buy these cars for personal enjoyment. You claim that an M3 is "more fun to drive". That's complete BS since "fun to drive" is a completely subjective category. My 2011 Fiat 500 is fun to drive in my opinion for example. Also, in the end driver capabilities matter more. I have a friend with a W203 C55 AMG who regularly slaughters M3 drivers on the track. How and why? Because he is a darn good driver with years of performance training and experience behind him. Just because someone drives the more track capable car won't mean they'll win if their skills suck - which is basically "everyone".

        "The RS5 wins outright. It has better performane, better dynamics, better handling, easier to live with, better interior- it just completely murders the RS5." So the RS5 murders the RS5? Man, you need to drive both cars in person before coming up with this typical magazine BS about how some cars "drive better than others". You remind me of a typical Car and Driver journalist when they compare a BMW to a any other car in the world. They'll testdrive the other car but the BMW stays parked in the shade all day and at the end of the day the BMW wins by default because "it drives better". Lame.

          The BMW wins because it drives better. Please go drive ANY BMW and then drive a Mercedes and tell me which one drives better. Hands down, the BMW wins. And yes, I have driven the C63 AMG. I came in expecting a lot, and I was severely disappointed. Sure, it may have amazing straight-line speed, but the steering is so numb that it feels like I'm playing a video-game.

          @Hailey Martin
          Well duh a BMW will handle better because that's what they focus on. A Mercedes is a luxury car with comfort bias and decent handling. And the "numb steering" you speak of in a C63 AMG is bogus. Virtually all reviews have commented on how direct the steering is. The C63 AMG is a capable track car, just not as balanced on the track as an M3, that's all. Your bias is clearly showing.

        Honestly, I think boring is extremely relative. Maybe an extremely experienced driver (such as Tiff Needle), would describe going 120 while a 4.2 V8 screams at 8000+ rpms boring...I wouldn't. Sure, going sideways is fun. Especially if you're a race car driver who's never does lest you lose the race. For everyone else, I'd wager extreme grip around tight corners is also pretty fun.

      Doing tests on a wet track is idiotic. Why? Cause nobody in their right mind would push any car hard in the wet, especially cars at this price point.

        @kaneda
        why is that stupid? In the UK and Germany you have in average more than 150wet days/year... so every RWD is 1/3 of the year out of the competition and are only good at the few days with perfect dry weather and clean dust free tarmac... so testing cars in typical UK/German damp conditions is much closer to real world as testing them in clinic like track conditions...

        UK and Germany get so much rain per year, if it hasn't rained yet that day, just keep waiting, it will.

      Expected results, considering the track conditions. The AMG is undoubtedly faster in the dry. It's really a toss-up between these two for me. On the one hand, the Audi is all-weather capabable and an exercise in high-tech engineering underneath gorgeous styling simplicity. Then, there's the Benz, and it's neo-muscle ethos w/ a luxury twist, wrapped in teutonic evilness. Can't go wrong either way, really.

      i hate when do these test on wet roads.. really ? awd is going to take the cake most of the time on anything but a dry pavement... but im impressed with its RWD setup the benz did not do bad all all agaisngt the AWD. I bet the merc would win on a dry pavement.. and the merc is the car I would have out the two also... not in that red tho.

      Both cars are a fine choice, too bad that Audi's RS cars aren't yet available in USA...

        @Alex
        What the hell are you talking about ? Just about every RS model is available in the US. Do some research, this isn't 2001.

          ahhhhh WRONG....... Currently audi only makes 3 RS models. TTRS, RS3, and RS5. Only the TTRS is sold in the US. before that the RS6 was not offered in the US. The last RS model the states has had was the 2008 RS4.

      I would rather take the RS5........it looks better and handles better in the rain....inconsiderate that a plus, also I don't like the engine note on Mercedes......its overkill to my ears.. -_-
