5 things you need to know about the new BMW M5
The M5 keeps its cool when you’re not
To maintain reliability, bits of the new M5 have also been upgraded and redesigned to keep cool. With around 700Nm of torque hammering the all-wheel drive system and eight-speed automatic, things are going to get very hot… So the engineers at M have design a special sump housing and larger pumps to stop fluid boiling.
Both the oil and water pump have been changed for higher capacity units, and they push the coolant and oil through revised capillaries. The all-wheel drive and transmission oils are also now run through a finned aluminium oil sump housing, unique to the new M5.
