I would too take the 5.5 TT, but we won't see that one in the C-class, with the exception of the BS perhaps. Madness

Um.....to my knowledge the clk63 5.5 turbo amg did have the m157 engine in it (or maybe it was the cls? not sure). Please correct me if im wrong. the car i drove was a prototype thats not available in the states yet.

Man , you should listen a turbo at WOT with Sport+ enabled and then edit your post

I agree that at idle and low rpm the sound is just like any other car

I wonder how the new GT3 RS 4.0 sounds

I have a 996 turbo with a free flow exhaust that I've driven at WOT side by side with the GT3RS. They still sound better to me. Just a personal view.

I drove the 2012 CLS63 yesterday at the AMG Performance Tour in Monticello...pretty sure thats the M157 in there...I can say the power was very impressive - it felt like a rocket once it got up to speed but there was some perceptible lag down bottom...the C63 was significantly more fun around the track (CLS63 feels like a boat in comparison.)

Holy cr@p!

I just reviewed the entire Inside Line article. The S63 PP actually put down 536 HP at the wheels which should translate to around 650 HP at the crank (using 18% drive train loss). Can this be true?

Not to mention the absolute monstrous torque this beast is putting down.

I'm absolutely in love with my 6.2 but on paper the new 5.5 TT blows it away.

It´s got 10 more HP than the SLS and we all know that the 6,2 engine in that car is not rated at 640 hp. Something fishy with that dyno.

I guess the only thing we can conclude from this article is that the new 5.5 TT is rated above the SLS which would place it around the 585 FWHP mark. Still not too bad.

Having recently driven the 2012 CLS63 with the 5.5 Bi-Turbo, the 6.3 and 5.5 have different characteristics altogether. Not just from the aspect of HP, but torque, as the 5.5 makes its torque at low rpms, and pulls hard right from the dig. Feels stronger than the 6.3, but keep in mind that the 6.3 is no slouch. I will keep the 6.3 personally, as theirs no replacement for displacement, unless you have turbos
