Has anyone actually measured the weight of c63 sedan or coupe?

I looked up on the mbusa website and found the weight to be higher for the coupe (compared to sedan, which was interesting). But more interestingly, the weight was lower than what I expected. It was 3600 lbs for sedan and 3800 lbs for the coupe. The links is: http://www.mbusa.com/mercedes/vehicl...nt=model-specs

So, the question is: Why is coupe heavier? And why is the sedan so light? Also, does this mean that the 507 edition cars are even lighter due to the shaved pounds in engine and hood?

I posted a similar question in the parts weight sticky a few days ago but didn't get any answers so I figured I would post a dedicated weight thread.

Simplest explanation is the all glass panoramic roof. that should account for at least an additional 100 pounds.

Great thread, as I too have been wondering about the weight differences. Also I'm wondering as no one has yet to answer whether or not the 19 inch 507 wheels are any lighter?? In addition to the hood and the brake rotors

Same question here about my 507...I have a set of race scales for setting up my 911, might be time to see what this beast weighs in at...

For me, new to the 507, the C63 and Mercedes overall I was very surprised to see a spare tire along with a jack/tools etc in the trunk. Why no run flats?

I had run flats on a Jeep SRT8 and that was an SUV - thought that was the norm these days for performance oriented cars. Sure fire way to lose 100lbs right there...and again it all adds up.

Audi and Land Rover are making great strides in reducing the weight of vehicles and it shows in performance figures. Weight reduction helps all aspects of performance, not just straight line.

As for glass - it's heavy.

I really wish the glass roof wasn an option instead of standard. I could care less about a panarama roof... I'd take a CF roof in an instant if I could!

i believe typically coupe versions of cars that were designed as sedans tend to be heavier because they need additional reinforcements in the body to make up for the missing center pillar

I had my car weighed earlier in the summer. with my mods and spare tire etc i came out to 39xx. need to check to find exact number. noone was in the car at time of weighing. and you also have to factor in the weight of gas

That's usually the case with convertibles. I wouldn't be surprised if that was true for coupes, too.

Wow so it is realistically 4000lbs. I was thinking of removing the spare, putting in a lithium battery and replace the trunk lid with carbon to get in the ballpark of my gt3 but that only works if we start from 3600lbs, not 4000.

Ahhh......another who had a Jeep SRT! Glad to see. I just sold mine last week, and I am having the 507 take over for it. Good to see man.......take care! Wes

When i bought my c63 i was surprised to see the jack/tools n spare tire but took them out the first thing when i got home, dont see the point of keeping them in when Its only been driven around town.
Remember my 1st gen audi TT had only an emergency tire repair canister instead of the spare tire/tools. Audi is def a few steps ahead in weight reduction.

Hood too

Another SRT8 previous owner here too... except mine was a Charger SRT8

For 507 edition, isn't the hood already carbon?

Stock 3910 lbs w/ 1/4 tank of gas. No tool kit no spare tire.
Modded 3550#

As far as I know the hood is aluminum, lifted from the SLS.

I had an 06 so we had the same Gen - I was waiting for the new gen to come out but it got porkie, weight wise and did not have much in the way of a HP boost. Then I waited for them to put a SC on it like the Challenger...then I got tired of waiting and got a 507. Maybe I will return to SRT at some point...


I think the first gen is the best - raw grunt, lightweight, bullet proof and of course cheap in terms of bang for the buck.


The new ones are pushing $70k with options - bit much for what you get in my mind.

I had a brilliant black GC SRT8 also, 2007 model.

Get a fiberglass hood?

I was told they moved the battery to the rear for better weight distribution. If you take all the stuff out of the trunk you basically just lighten the rear and change the weight distribution. I don't think this would help with the wheel spin issues these cars have. I like the idea of swapping out the hood as well since this would keep the weight distribution closer to stock. Of course I have no idea if the stock weight distribution is ideal, but i trust AMG over me just taking stuff out of the car.

Feel free to tell me how wrong I am.

I don't think either number on the MB site is correct. I believe both cars are basically a tick under 4000#. I always weigh cars fuel of fuel, for the sake of consistency. Haven't had a chance to get my car on my scales yet… doh!.

The coupe has a B pillar.

In order to get a C63 to the weight of a GT3 you'd probably need a sawzall (remember the SCC Sentra?).

coupe weighs a little more due to the panoramic glass roof as someone already stated.

m5trol

Right, not even going to try. I put a stroker in my E60 M5 and the character of the car changed completely, it just became something else. I think for now I like the c63 the way it is. We'll see down the road if its worth changing its handling and driving character.

I think the BS (507) hood is aluminum. The facelift cars all have aluminum hoods.

The front rotors have aluminum hats and are a little lighter than the solid cast iron rotors.

My 2013 coupe race weight is 4130lbs (-210lbs for me so 3920lbs wet).
