Common sense has left the chat

Both cars pretty much have the same tread traction to weight ratio, if anything, the video shows the BMW has more traction than weight compared to the mustang, tho can be human error when starting to brake or the exact speed.
-
@@junatah5903what mustang are you seeing that we’re not?
-
@@Solidsnake9121my bad, looked like a mustang from the quality of the video.
All be it makes even more sense considering how heavy BMWs are in general.

Hybrid regen plus huge brakes seems like it could potentially win
-
This is exactly how it’s going to work because physics. The softer suspension making weight transfer stronger+bigger tyre surface+more mass=more traction on the front wheels which means no skidding and better braking. HOWEVER, this also means the brake temperature and front tires are degraded much more. This works only for emergency braking, continuous brake use will make them fail very fast due to the weight and friction.
-
Heavier vehicles usually means wider tyres, it also means more force into the ground due to the weight, so you get more grip when braking and more traction.
-
If you look up the friction force formula, you will not find the surface. Only friction coefficient.

It has nothing to do with Regen and little to nothing to do with brakes (other than perhaps better abs management). Pretty much all cars have 4 wheel brakes that are powerful enough to lock up the wheels. It comes down to tires, weight and perhaps some aero although very little of the latter.
-
Possibly brake pads and rotors, too.
-
Bigger brake pads and rotors help.

Entire internet failing to understand contact patch from big tyres being the deciding factor:
-
What are you fail to realize those are tuned vehicles with the exact same thickness of tires all around so no that makes no difference. The only actual difference between these two cars when it comes to stopping is the weight
-
@@GreenTheScreen123 dude the tyres on that suv thing are visibly larger lol
-
@@GreenTheScreen123 a heavier car is harder to push than a light one; same goes for the opposite, it’s harder to stop a heavier car.
Kinda is common sense. As other comments have pointed out already, is more about the human reaction time (skill issue) and the quality of brakes/tires.
-
-
Bigger tires and bigger brakes means better stopping distance
-
And also more air resistance
-
That is all needed to counter the extra weight.

The stag would never let that happen

Having owned an FK8 that had excellent two piece brake rotors/much wider tires than my similarly powered Honda Accord 2.0t with its heavier weight/skinnier tires/much smaller brakes…the difference is crazy different/definitely scary in a panic stop situation…as in is this Accord going actually hit the vehicle in front of me that I had a large safety bubble not moments before. Wider tires/wheels definitely make a difference and possibly upgrading to a manufacturer’s performance brake options/or aftermarket…to eliminate any factory braking system/vehicle weight handicaps.
-
Why don’t they measure the braking distance with vbox and use the real measurement? Then reaction time is taken out of the equation. Would like to see a leader board based off fact
-
5 times in a row! Please
-
A real test is the same vehicle but one loaded with more weight than the other then see if heavier is better my guess is no
-
weight balance, angle of momentum, larger tires. All of that has a effect. The the experiment was not done using the scientific method and the results are still within margin of error
-
No, it’s because of the shape of those cars
-
Everybody’s saying wider tyres but i don’t think that’s the reason. An XM Label Red has 275 front and 315 rear whereas an m4 comp has 275 front and 285 rear but the m4 must have wider tyres than regular competition since it’s manhart.
-
Better and steady during winds
-
More weight transfer when the center of gravity is higher
-
That looks like a Durango smh
-
A heavier car means it both has more grip and more kinetic energy (which is the energy that needs dissipating to slow a car down). The two are both proportional to weight. So weight isnt really a factor.
Its mostly dependand on tyres, human reaction time, mechanical reaction time, quality of the braking system (if all wheels are really braking on the mechanical limit of losing traction).
