How to tell the difference between a CLK63 and CLK 550?
I am trying to determine how to visually differentiate a CLK 63 cabriolet from a CLK 550.
Does the 550 have the dual outlet exhaust as well?
The CLK 63 runs a 12.5 quarter mile correct? What does the CLK 550 run?
I never noticed these cars before, but ran into one late last night. I was on a back highway, pretty empty stopped at a light, It turned green and a convertible CLK creeps up next to me and floors it. As the road was empty, I thought I would pass him with ease.. well, he put a car length on me and I didnt pass him until 120, and finally had a decent lead by 145.. He passed me and gave me the thumbs up, but I didnt get to talk to him or see more than the dual tips and CLK and swore I saw a "3".
My car is an 03 cobra convertible that at last count put down 450hp and 479ft/lbs, so I'm assuming this was the 63?
Either way.. beautiful car and awesome performance. any more info you guys can provide would be great.
Thanks! :-)
http://youtube.com/watch?v=zzJEFy72rKo - that's a coupe so it's got 4 exhaust tips.
The dual exhaust on the CLK63 convertible looks just like the CLK550's...
I'd imagine the CLK550 probably does the 1/4 mile in about 13.5 secs (??)
If it could run a supercharged Cobra, it was probably a 63!
Welcome!

2003 Corbra Mustang Specifications:
The Roots-type supercharger and water-to-air intercooler to the Cobra's 4.6-liter, DOHC 4-valve V-8 engine bumps output to 390 horsepower with 390 foot-pounds of torque.
Curb weight: Coupe: 3,375 lb (1,531 kg) Convertible: 3,565 lb
Mercedes Benz CLK 63 AMG Specifications:
Power bhp (kW) at RPM: 481 bhp @ 6800 rpm and Torque lb-ft (Nm) at RPM: 464.7lb-ft @ 5000 rpm.
Curb weight: 3869 lbs
If it was me, I would have stopped at 100 mph as that would have been sufficient to prove a point. No telling what the other person's intent was but German cars are generally get faster at the top end due to configuration for high speed driving.

Honestly it couldve been a 550 or 63 AMG who knows. A whole lot of W209s are modified some way somehow so it could've been either or!

The numbers above do not reflect power to the wheels as that is not how such numbers are normally reported. You need a dyno to really determine that number. I don't own a CLK63 so an actual owner can provide their input.
BTW - the calculator on race car is backed pretty well by my 'street" mustang - my trap speeds almost mirror what comes out, and I have had the car on a rear wheel dyno on several occasions. My ET's are limited by my driving ability - trap is just how far you can push the pedal.
They run 13.1 - 13.3 in the 1/4 mile regularly stock.
The W209 with 6.2 Liter (non BS) runs high 12's on street tires from what I gather.
But prob a tune and tires away from low 12's?

Besides the rediculously incredible exhaust note, the AMG from the ground up design of the M156 engine makes this car amazing.

Marcus has the specs up for these cars (marcusfitzhugh dot com), and I trust his stuff. My car weighs 300lb less than a 550, and has 10 less hp, so it should be a bit faster. If these numbers are correct, you have a very stout motor in your car.
Most reports are they do 60 in just over 5.1 seconds, which would not correspond to a 12 second car with decent traction. The CLK55 ran it in 4.9 on the same spec pages.
The wgt/hp calculators are just estimates..... you have to take into account the sweet tq of these beasts as well which I'm sure the calculators don't.
