التجربه شيء مختلف ..
ثم أنه
V is equal for both
M is bigger for the mercedes
which means that .. the mercedes will have a more kinetic energy but doesnt necessairly means it needs a longer distance

which also leads to.. with more brake power .. you can make the mercedes stop in the same distance or even less

so CONCLUSION : at the same speed its IMPOSSIBLE that both have same KINETIC ENERGY
but its fairly probable to make them both stop in the same distance

life example

the Kia Cerato is heavier than Hyundai verna ( which i own ) by about 300+ Kilos
and yet the cerato has a more brake power and obviously can stop in a shorter distance

انا متأكد 100% ان التجربة شء مختلف

Mercedes K.E is >Hyundai K.E ,both will have same road conditions so subtract it from both K.E .i think Mercedes will have more Air Resistance and Tyre Friction than Hyundai,because
Friction =u*Reaction from ground which makes the car equilibrium so Rg=Car Weight

Braking power from Merc ofc Bigger than Hyundai,that doesn't mean it will overtake the 2x difference in weight
Here it is with numbers
Both cars at 100km/hr
Mercedes
2000*100²=20,000,000J
Hyundai
1090*100²=10.900.000J

Do you think that the max friction force done and roughest conditions against Mercedes only and the very high braking power will achieve 9,000,000 Joules
even if we take off 5,000,000J off for brakes (i don't know actual number)l
I know Theory is impossible to be accurate but that doesn't mean it is wrong

وطبعا فى الاخر اختلاف الرأى لا يفسد للود قضية:)
