1.1.�Highlights
The�S58�engine�is�the�successor�to�the�S55�engine.�Like�the�S55�engine�in�the�BMW�M4�and�BMW
M2�Competition,�the�S58�engine�is�based�on�a�BMW�AG�standard�production�engine.�The�S58�engine
is�based�on�the�B58TU�engine,�as�the�engine�identification�highlights.
Technical�updates�and�modifications�of�M�GmbH�make�the�engine�suitable�for�motor�racing.
With�its�turbocharged,�high-revving�design,�the�new�M�engine�delivers�impressive�and�undreamt-of
power�development�with�a�nominal�output�of�353kW/480hp�compared�with�the�317kW/431hp�of
its�predecessor.�The�maximum�torque,�an�indicator�of�the�power�delivery�and�performance�perceived
by�the�driver,�has�risen�from�550Nm�to�600Nm.�This�has�been�achieved�despite�the�fact�that�fuel
consumption�and�CO2�emissions�have�been�reduced�with�the�aid�of�the�BMW�EfficientDynamics
measures.
As�the�S58�engine�is�based�on�the�B58TU�engine,�it�has�been�possible�to�carry�over�a�number�of
engine�components�from�the�B58TU�standard�production�engine.�The�other�90%�of�the�engine
components�are�new�developments�or�synergy�parts�with�the�B58TU�engine.�All�the�technical�data�is
above�that�of�the�predecessor.
