It's been confirmed for some time that Mercedes-Benz is developing a new two-door coupe version of its C-Class to replace the current hatchback CLC model. With that in mind, it should come as no surprise that Autocar is reporting that Mercedes-Benz is also working on an AMG variant of the coupe to go up against the Audi RS5, BMW M3 and Cadillac CTS-V.
The British magazine is reporting that the coupe will use the same AMG 6.2-liter normally aspirated V8 as one of our favorite Benz sedans, the C63 AMG. However, if this car is to debut later in 2011 as projected, it would seem logical that Mercedes might switch to the new twin-turbo 5.5-liter V8 that's going into the 2011 CL63.

The turbo V8 could the output from the current 451 horsepower to somewhere closer to 500 hp. Autocar also speculates that a C63 Black Series coupe could be a followup to an upcoming SLS Black Series.

      I am not surprised one bit, natural evolution, a truer M3 fighter.

      C63 AMG coupe and SLS Black Series , good times. but i still think the E class coupe needs an AMG version , that car feels so incomplete without the AMG touch.

      "The turbo V8 could the output from the current 451 horsepower to somewhere closer to 500 hp."

      More than likely AMG will 'amg'-ify the 4.7 turbo V8.
      Pass on 6.2 & 5.5 turbo

        The C63 is faulted for being too front heavy, and has plenty of power.
        To rectify that, a shorter engine should be used. The 6.2 V8 has larger bore centers than the 5.5 (I don't remember if the 4.7 has the same spacing as 5.5)
        In the interests of better mileage the smaller engine can be slightly tweaked to match the current 451hp, exceed the 443ft-lbs, and meet emissions targets.

        That's always possible, but I don't necessarily think it is likely or more than likely. I'd say it's just as likely, if not more so, that the 5.5L will proliferate the entire AMG lineup at some point, just as the 6.2L does now (aside from the SLK).

        Either way, my guess is that the coupe will get whichever motor the sedan has at the time it is released. So, if the sedan sticks with the 6.2L V8 for the next year or two, then I think the coupe will stick with that as well. It the sedan is slated to get the 5.5L (or something else) by that time, then so will the coupe.

      So much for an end to the horsepower wars eh?

      I'm definitely not complaining though. That winning lottery ticket can't come around soon enough...

        bring it, but give me the 6.2L NA engine

      Finally, a legit competitor from Mercedes to the M3 coupe!

        Personally it's a tough choice between NA and Turbo.

        For the 6.2 (6.3 they call it ha!) Merc engines the sound is simply insane. They along with the Aston Martin DB9/V8 Vantage series, Ford Shelby GT500 (2011), Audi RS4, Challenger SRT8 and LS3/LS7 engines are among the best engine sounds out there on the low end of the pitch scale with the Ferrari F50 etc occupying the high strung insanity). The Shelby is the Supercharged one here but that does not take away the snarl.

        Also, the NA engines have a linear feel, especially with large displacements as they have a flat torque curve.

        Moving onto Turbos (I own a chipped maxed out turbo), they sounds bad (other than the waste-gate). That said, what I love about turbos is the ability to get significantly more power than the manufacturer shipped it with for less than a thousand bucks. They are inherently more 'tunable', the exception being the Vette engines (which get big increases with cams etc). Ex: 2.0L Turbo in the Audi TT is worth 330HP easy (and 350HP in the EvoX), 3.0L turbo in the 335 is worth 400+HP.

        I can only image what a 5.5L TT V8 from MErc that ships with 500HP is capable of. DROOL. But, those dang 6.3's sounded so fine and in the case of the C63 was detuned anyway.
