[QUOTE=NS_C63;3566531]I found the speedo to be off by about 5km/h./QUOTE]

Mine too, indicated 100km/h, actual 95km/h (using a Garmin GPS).

If these speedometers are off this much I wonder if the odometers are off as well. If the wheels and tires are stock the actual miles driven and current velocity should be much more accurate than the posts here indicate. Very frustrating for a car to be accumulating miles that were never driven.

I don't know about MB (cause mine won't be built until August), but I know BMW is optimistic on the speedo, but the Odometer is dead accurate. Checked it with a GPS.

I have gone 155mph and the damn thing had more left in it

Note: Did it on a public road, a rather long straight public road.

C63 will NEVER hit the 200 mph mark. Not possible due to the aerodynamics of the car, atleast not while being stable. Do you have any idea what the lift is on a car capable of 200 mph? We are talking a 4 door sedan, not a super car.



190 mph and the C63 will be shaking like the chassis is about to fall apart. If you are think you can push this car to 200 mph you're crazy. Regardless of HP #'s, etc., the chassis can't support. There is a HUGE difference between a C63 and super car chassis.

LOL

Unfortunately I agree. My guess would be a stock C63 might pull into the low 180s completely delimited.

And what about the Brabus Bullit? Its top speed is elec limited to 225mph. Some of the tuners here were getting 200mph with the W203 C32. If my memory serves me right I remember reading (over 20 years ago) that all MB cars were built to with stand speeds of 300kph (approx 186) and the 190 W201 being the smallest back in the day. These cars are alot better at high speeds than one thinks.

Your on a planet all by yourself. I promise you a C63 can hit 200-- maybe not stock, but the Brabus Bullit with 730BHP can start knockin' on 230's door; yup... enough to leave your GT3 and most other so-called "supercars" in the dust.

Top speed is endless if you continue to mod the car. I'm talking about a bone stock C63. PP or not, the chassis and aerodynamics of the car are going to prevent you from getting to the 200 mark.

Brabus, Kleeman, etc., are modded cars, and even then there is a huge difference between a supercar and a modded C3.

You cram enough HP in a Ford Pinto, it'll do 200 mph too. I just wouldn't suggest it unless your trying to see how many flips you can do from 200 to 0.

If 200 mph were such an easy thing to accomplish, there wouldn't be super cars. There's a lot more to doing 200 mph than just cramming motor and gearing in the car. You upset the chassis of the car at 200 mph and bad things happen.

230's? Seriously? Was that in the brochure or did the salesman tell you that? Brabus or not, there's no way in hell.

I guess there are gonna be a lot of pissed off Veyron customers when they find out they could've bought a Brabus C63 and kept another $1M in the bank.

GT3 will get sloppy at 185 mph and that chassis will smoke any car MB, BMW, etc. can bring to the table (excluding SLR.)

Again, there's a huge difference between a super car and a high end luxury car.

The drag coefficient Cd is equal to the drag D divided by the quantity: density r times half the velocity V squared times the reference area A.

Cd = D / (A * .5 * r * V^2)

And that being said, the C63 is a brick of a car. It doesn't have the aerodynamics of a 200 mph car.

Me still loves mine though

I absolutely love and lust after the GT3. That said, correct me if I'm wrong but I was under the impression that the M5 or M6 (when delimited) would do 200 mph. I also assumed that the 65 AMG cars would do it as well when delimited.. Technically delimited is not stock but...

I would speculate that an otherwise stock (but delimited) C63 should be good for approx. 185 mph... Pure guess though..

FYI while on our way to get to where this photo was taken, Car #6 and Car #1 both went beyond 190mph. Car #6 required a repaint of the front end after following to close behind #1. I myself was driving car #7 at a more reasonable autobahn speed and watched these two leave the group like we were standing still. Of course names are not being mentioned here to protect the innocent.

Theoretically, almost any car *could* achieve 200 mph if you put enough HP behind it, but the question is if its stable or not. If the chassis gets sloppy and upset, you may find yourself completely out of control.

Look at the chassis of a Ferrari, Lamborghini, Bugatti, etc. and you'll see that those cars were made to sustain 200 mph and do it while still being totally controllable. You can actually "drive" at 200 mph in those cars, turns and all. You take a turn @ 200 mph in a car that wasn't made to do 200 mph, and you're playing Russian Roulette.

Ever done a sudden move in the C63 at 90 mph and get that "swaying" feeling. Like when going into a turn really hot and on the brakes and then a second or two later the car seems to settle in and its smooth? That's the chassis. What do you think this chassis is going to do at 200 mph? You think that tiny little lip spoiler on a C63 is enough to place the downforce required on the *** end of the car to keep it stable at 200 mph?

Plain and simple, most cars aren't designed with 200 mph speeds in mind. The ones that are have pretty big price tags. I think the C63 is probably STABLE up to about 165-170 and beyond that you are playing with fire. Problem is when you push past the stability of the car, you won't know it even happened because you'll be dead already. It might seem ok and then BAM! You're dead.

The Carerra GT is about the only car in that group I would even consider pushing past 180. LOL

I had my old GT3 up to 175 and it did it, but didn't like it too much.

At 90 a swaying feeling in a AMG C63?? now your talking crapola, check your tire pressure dude!!

Under sudden braking, quick turn in, yes.


Do this and you'll know what I mean:

1. Get on the eway and do 90 mph.
2. Get off at an exit that has a winding turn. Imagine a C shaped exit ramp.
3. Late brake it and go in hot so your still on the brakes to the apex of the turn and then slam the gas peddle to the floor at the end of the apex.

You'll get the feeling that the car is gonna lose it. Hopefully you don't. I do it every morning on the way to work. Makes me all day. In my GT3, I could take the same turn 25-30 mph faster than in my C63 before I get the "I'm gonna lose it feeling."

Very interesting perspective there Danny, please proceed.

Again, very interesting-- but hold up, you just said it could never be done now your saying with enough HP? Whatever happened to "regardless of hp"?
You go from talking about "stock" to even modded with endless power it wouldn't matter. Limitations of aerodynamics and the chassis, right?

Well, whatever let's see your next foot-in-mouth post:

Make up your mind already will you. And quit talking about 200MPH "swaying" and "sudden turns" like people going 200 are racing through the Corkscrew at Laguna SCEA. Fact is, you do any sudden turns at 200-- I don't care what car your in, your going to end up in more pieces than a Transformer bot.

Your mentioning "wrong moves" and "swaying" and all that like super cars aren't affected. Sure, the body roll may be more excessive in a C63 then a Murcielago-- but that doesn't mean the C63 wont push 200MPH all the same.

I don't know why I even bother to argue, there are members here who have gone past 180 and have gotten very close to 200:

Yes, we get it-- if they would have exited the freeway and threw on the e-brake, the "sway" would have caused them to crash! BAM! Just like that...

Really? Smoke any car from MB/BMW?

I got a lovely star-gazer suffering from a broken IC Pump that would put your GT3 in it's rear view-- I would know, I already raced a lovely white one.

Maybe not on a track, but nobody here has been talking about turns, Einstein. And an M6/M5 S65/CL65 "etc." would do all the same to your crunched up Beetle with a wing on the back.

Thanks for jumping in, the longer I am on this forum the more professional idiots I see.
