usually the cars are heavier and much faster, need more force to slow the car and this generates more heat.
The reason for multi pot calipers is due to the fact they use large pads. These pads cool faster, but you need more expensive calipers to evenly press the whole pad surface to the disc.
Also the customers expect fancy brakes whether it will help them stop quicker or not...
As welshpug mentioned. Something like a Porsche will have far superior outright grip, control of weight transfer so it can use better brakes to greater effect.
