Deliver a standard X5M or X6M to the small but highly experienced specialized German engineering and manufacturing outfit and they’ll nearly strip it back to a skeleton. All that’s left of the engine is the external look, which remains the same than in the standard cars.
It all starts with the disassembly of the standard engine, leaving only the external parts of the engine unchanged.
First, the cylinder block undergoes the process of machining (boring/honing) to fit the new NOWACK MOTORS oversize high performance pistons. Afterwards, a unique Alusil coating is being applied to the cylinders for less friction. An all new, fine balanced NOWACK MOTORS exclusive crankshaft, individually weighed and fine balanced high performance connecting rods, 8 fine prepared, especially
coated, exclusive high performance pistons with new valve pockets, specially coated piston rings and piston pins, high performance camshaft (in-/outlet), special intake valves with bigger diameter, extensively modified free flow high performance cylinderheads with re-engineered in- and outlets, each optimized on NOWACK MOTOR’s in-house SuperFlow 1020 flow bench, high performance camshaft (in-/outlet) and various modified components of the valve drive inclusive of special valve springs

The optimization of the intake air flow inclusive of high performance free flow air filters, modified high performance exhaust manifolds leading to an all new, complete NOWACK MOTORS high performance sport exhaust system inclusive of high performance motorsport catalytic converters and rear silencers, complete the list of external hardware components.
Upon completion of the mechanical manufacturing process, each car’s ECU is being individually re programmed. Needless to say that the works speed limiter is removed and set to 330km/h.
The maximum power of 715hp and torque of 845Nm at 2.600rpm. offered by this most sophisticated, bespoke powerplant can be seen as an impressive side effect resulting out of the extensive engineering and manufacturing knowledge.
