Per Mercedes the C43 Sedan without pano roof weighs in at 3,759 lbs and the C43 Coupe with the standard pano roof weighs 3,935 lbs and that's a difference of 176 lbs.
Sedan is bound to be faster given the parity of all mechanical bits.
Depends on more than just weight and parity of engine / transmission. Anyone know the coefficient of drag of the sedan vs coupe?
C&D's curb weight of the C43 coupe they tested was 3908 lbs, 27 lbs less than what MB quotes.
I only point this out as it is extremely rare for them to test a car that weighs less than the manufacturer's listed spec, due to optional equipment. This might actually be the first time I've ever seen that (granted, I don't pore over every last detail for every car review I read there.)

Reason: math

yes panoroof is around 80 to 100 lbs and then you have the structural differences between coupe and sedan...
I say 4.1 seconds 0-60 whether coupe or sedan is great. The 4matic awd system is great as well. I'm not sure if it's on par with Audi's Quattro tho.
But now we're just splitting minor differences.
haha indeed! Much better to go outside and go for a long nice drive by the river, now that is what the c43 is made for! Well besides stay quiet and calm in the rain and snow...but that never sounds so cool...
Spoiler alert! C450 owner here to rain on your parade.
Half a second faster 0-60, but the quarter mile is only a tenth better. This tells me that adding 2 extra gears helped the hole shot, but gear changes take time. So much time that by the quarter mile the old car almost caught up. I'm curious to see how the c450 does head to head against a c43 in a standing mile.
I'm just saying more gears isn't necessarily better.

I was saying this a while back. The 0-60 is achieved with better gearing for 0-60. Just like the cayman is poorly geared, giving it a slow 0-60 time. The C450 is not poorly geared, just geared differently and slightlyworse than a c43.
They are still powered by the same engine and as long as the drivetrain loss is pretty much the same (the numbers indicate they are) then it's just as quick.
At the end of the day, this marginal difference is negligible for the type of vehicle it is.
Are you implying that the drag coefficients between the 2 cars have an effect on either 0-60 or 1/4 mile times?
I am indeed implying that a difference between the coefficient of drag between two physically different but mechanically similar vehicles can have a difference on the speed of either vehicle.

You guys should be happy that Mercedes-AMG is now ahead of the game. I remember when BMW first brought out the 2007 335i sedan/coupe and they were killing everything and it was fast back then. Then Audi brought out the s4 and it was over for Mercedes at least in regards to performance with the lethargic engine that was in the c350 (which I had).
Now Mercedes has class leading accelerations with the AMG-43 line-ups across the board and you guys are bickering over tenths of a second between c450 and c43 lol

What is said difference in the 0-60 and 1/4 mile times of very similar cars with very similar drag coefficients?
Answer: Absolutely nothing at the speeds in question for either car in both tests.
Now if you had significantly different drag coefficients and were trying to go 300+kph..............

Exactly. Drag is inconsequential with respect to acceleration and top speed at the velocities that most passenger vehicles travel at. OTOH, when I'm trying to develop a rifle load that achieves a specific velocity at a given range, the ballistic coefficient is very significant. In this case, the car may have a top speed of 155mph while the rifle projectile is close to 2000mph.
Since drag increases with the square of velocity, small differences in the coefficients will become significant at very high velocities while remaining insignificant at low velocities.
I have no idea how people are getting 4.1 seconds? I have tried every mode, elevation and settings but the best I'm getting is 5.3s 0-100kph. Kinda dissapointed with this car atm...
Select S+ with ESP OFF. Left foot on the brake. Right foot on the throttle. Release brake and there you go. Your car will shave off 1s from your 5.3s 0-100km/h (62mph).

best I could do with such method was 4.6s (Racelogic VBox Sport, +22C ~50% humidity 100m elevation warmed up tires)
one pedal floor delivers 5.1-5.3s with same conditions
cold tires will result in extra 0.2-0.5sec higher results
