2023 S63 791hp @ 1055 ft/lbs at 5721 lbs curb weight
2022 S500 429hp @ 384 ft/lbs at 4610 lbs curb weight
S63= 0.138 PWR
S500= 0.093 PWR
Only 0.045 difference plus all that extra weight slinging around the corners in the S63
Hmmm...
What is the power-to-weight ratio:The power-to-weight ratio represents the ratio between a vehicle's power and its total weight. The higher the PWR, the faster the vehicle will accelerate. It is for this reason that motorbikes accelerate quicker than most cars. They may not be as powerful but they are lightweight; as such, they are likely to be faster because they have a higher PWR.
PWR calculations are commonly used to predict vehicle speed.
Let's say we have a vehicle that weighs 1500 pounds and has a horsepower (hp) of 200. Its PWR will be as 0.133 hp/lb, which entails that it has a power output of 0.133 hp for every pound of weight.
Calculating PWR
It's very easy to calculate a power-to-weight ratio. Simply divide the power output of a vehicle by its weight. For example, if you have a car that weights 2000 pounds and has 250 hp, the PWR will be as follows:250 / 2000 = 0.125 hp for every pound of car.
Power-to-weight ratio (PWR) formula
The power-to-weight ratio calculator uses the following formulas to calculate the power-to-weight ratios:PWR (hp/lb) = P (hp) / WT (lb)
PWR (W/kg) = P (W) / WT (kg)
Where:
PWR = Power-to-weight ratio (horsepower per pound, watts per kilogram),
P = Power (horsepower, watts),
WT = Weight (pounds, kilograms).
Conversions:
1 Horsepower per pound (hp/lb) = 1.64398682456 Kilowatt per kilogram (kW/kg)
1 Kilowatt per kilogram (kW/kg) = 0.6082773809745355 Horsepower per pound (hp/lb)

E-ABC for example have curve mode at least the body roll might be managed that way.
Looks like MB hit a bumpy road, I mean to be fair, the SL was very overpriced to begin with.
I’ll test drive the S63 (if they have one available).
I’ve owned a lot of cars in my life and IMHO weight really matters. A car like the S580 is heavy enough as it is. The S63 takes it to another level and is a huge negative.

2023 S63 791hp @ 1055 ft/lbs at 5721 lbs curb weight...S63= 0.138 PWR
2022 S500 429hp @ 384 ft/lbs at 4610 lbs curb weight...S500= 0.093 PWR
Alternative, using the reciprocal,
2023 S63 5721÷791 = 7.23 lbs/hp, meaning one hp will push 7.23 lbs forward
2023 S500 4610÷429 = 10.75 lbs/hp, meaning one hp will push 10.75 lbs forward
For the same horsepower, accelerating a weight of 7.23 lbs is much easier than accelerating a heavier weight of 10.75 lbs.

Huge numbers both torque and hp but that crazy weight nullifies the gains.
First time I am not on board with an S-Class AMG since my first, back in 2001, CL55 (I know it is not S-Class sedan but effectively it's 2 door brother).
Instead, waiting for the Sapphire which I am curious about after having the Dream Air rental for a week in LA.
