omg OMG omg can u belive it???/

4900 pounds with 429hp and it trap 4mph higher then my 388hp 3800 pound coupe..

What do u guys think the CL63 will do in the 1/4mile?

I'm not surprised because it the new twin turbo engine which has about 80% of the torques avaliable @ around 1500 RPM. I believe it also get the new 7-sp which help alot in acceleration.

True however, the OP was referring to the 550.

The 2011 550's have the 4.6L twin turbo engine

I don't know if it was on DR's or not, but it did 0-60 in 4.21 seconds. Had 4Matic, damn imagine what the CL63 is going to do (to the CTS-V).

Imagine what the 550 will do when Renntech and Kleeman get them tuned.

That isn't an actual drag strip time. Someone is always posting magazine times over there on dragtimes as "owner" NA. They also add some made up numbers to make it look less rounded by going out to the 100th decimal place. For example taking a magazine's 12.8s @ 112mph 1/4 mile time and posting it as 12.810 @ 112.030mph.

They really shouldn't do that as the trap speed from a GPS based data logger will read up to 2 mph higher than a drag strip's timing lights. The drag strip uses an average of the last 66' to measure trap speed, while the GPS based equipment will measure the speed at 1,320'.

4.6L is correct however, it's a NA V8

I'm almost positive all new 11 CL550's have the 4.6 bi-turbo motor.
The last naturally aspirated motor in 2010 model CL (non-AMGs) had the 5.5 liter.

The new car, though keeping the same badging, goes down almost a liter in displacement yet gains two turbo-chargers.

Highly doubt Mercedes would downgrade the engine from the previous CL's 5.5L N/A engine to a 4.6L N/A engine. Doesn't make sense.

PCH

My bad, your correct.

Well lets say this car traps only 110mph, this E.T still has to be correct
12.8 1.4 mile, 0-60 in 4.2 seconds 0-130mph in 17.5 seconds!
Which is insanley fast for a 4900 pound car.

I'm not sure where you got your infos but you're wrong again. Just visit the Mercedes website and find out for yourself. Scroll dowm to pages 16 to see the spec, on the new engine.

According to Car and Driver, the new CL550 is a 4.6L direct injected twin-turbo V8. The CL63 uses a 5.5L engine.

Based on personal testing with my vbox simultaneously at the drag strip, I would even say that the ET at the strip is slightly better than a GPS based time (using a 1 foot roll-out) because it is more like a 1.25' roll out at the strip when staging shallow.

I agree that 110+mph trap speed is smoking fast, especially since this is the base model CL. The only other thing is that the CL550 weighs in at 4,650lbs (right around the weight of the old W215 CL65). The W216 CL65 is around 4,900lbs. But still the CL550 is pretty impressive.
