Before BMW goes ahead and replaces the current M5 sedan with the 2011 model year, Nowack Motors has unveiled a nicely upgraded M5 to celebrate the retirement of the BMW M V10 engine.
Known has the N635S 5.8 Hans Nowack Edition (yeah, we know, it’s a horrible name) the engineers at the tuning firm gave the 5.0L V10 some special upgrades allowing it to produce 708-hp. That will allow it to go from 0-62 mph a lot faster than you can say all the letters and numbers in the name. Visual upgrades are kept to a minimum since the real story here is all about the performance.
The same upgrade can be used on an M6 since both models carry the same engine. Nowack Motors is also offering a 12 month warranty on the upgrade without any mileage limits.
Hit the jump for the press release and the high-res image gallery.
N635S 5.8 Hans Nowack Edition BMW M5:
A farewell celebration for the naturally aspirated V10 masterpieces of the BMW M GmbH: NOWACK MOTORS created a world unique state-of-the-art masterpiece to celebrate the end of the era of high revving naturally aspirated BMW M engines, the N635S 5.8 “Hans Nowack Edition”, offering an unmatchable maximum power output of 718hp at 9.000rpm.
NOWACK MOTORS, the world’s no. 1 specialist company for engineering and manufacturing unique high performance engines on basis of all BMW M engines (4-, 6-, 8- and 10-cylinder) unveils a world unique naturally aspirated masterpiece, the N635S 5.8 “Hans Nowack Edition”.
The N635S 5.8 is a tribute from Oliver Nowack to his father Hans, creator of world famed race and road engines and one of the inventors of what is nowadays called ECU-Tuning. Hans Nowack was an overall technical genius who always had his own approach when engineering and building high performance engines, resulting in numerous glorious victories of his cars in international motorsports, like e.g. the victory of the European Touring Car championship with a BMW 635CSi with driver Helmut Kelleners. He never stopped to invent world-class high performance engines, and after his active career, he continued to be a mentor for his son Oliver, who followed him in his footsteps most successfully. Hans Nowack died in 2005, and Oliver created this engine to pay tribute to the lifework of his father.
It definitely is the pinnacle of all high performance engines ever built on basis of the M GmbH’s 5.0ltrs. V10 offering a standard maximum power output of 507hp.
Classic mechanical tuning techniques, the usage of the latest, most advanced coating materials and techniques combined with a most sophisticated, individual remap of the ECU were always NOWACK MOTORS’ no. 1 choice when increasing power and torque of naturally aspirated engines, further enhancing the thrill that only a naturally aspirated high performance engine provides. Forced induction, neither by supercharging nor turbo charging, never was an option to increase the performance of the 5.0ltrs. V10 engine as it does not suit the engine’s overall technical layout and characteristics. Furthermore, a forced induction engine based on a NA engine never offers the refinement and reliability of a perfectly engineered and manufactured naturally aspirated high performance engine. Thus, it is the ultimate challenge for every high performance engine manufacturer.
Each NOWACK MOTORS N635S 5.8 ?Hans Nowack Edition” is equipped with two NOWACK MOTORS bespoke intake air collectors with a higher air volume in order to provide the engine with sufficient intake air quantity.
The colour of the paintwork for the air collectors is being determined by the exterior colour of the car.
Only this time, the name differs from all other NOWACK MOTORS creations. The name does not reveal the actual maximum power output of the engine, clearly separating this unique showcase of highly sophisticated manufacture of internal combustion engines from the N700 4.8 with 715hp, the latest high performance engine creation based on the new 4.4ltrs. BMW M Biturbo V8 engine of the new era being used in the X5M and X6M. As we all know, this engine will be used to propel the upcoming new M5 of the F10 series by next year.
All internal parts of the engine are being replaced by NOWACK MOTORS’ high performance parts, thus every M5/M6 (also cars with a higher mileage), can be converted to a NOWACK MOTORS N635S 5.8 “Hans Nowack Edition”.
As every engine is brand new after the conversion, NOWACK MOTORS provides an engine warranty of 12 months without kilometer limitation.
