BMW M5 N635S 5.8 Hans Nowack Edition – Click above for high-res image gallery

With its award-winning V10, BMW's M division hasn't left us with much not to love. Save, of course, for the fact that it's not long for this world, pushed out as it will be in the next M5 by the company's growing environmental conscience. But before the twin-turbo V8 spells its demise, Nowack Motors is giving it a suitable farewell in the form of the N635S 5.8 Hans Nowack Edition.

Having ruled out forced induction, the BMW tuning house has fitted the 5.0-liter V10 with a pair of new intake air collectors, a remapped ECU and retooled engine components. The result boosts the stock 507-horsepower motor up to a mind-boggling 708, dedicated by Oliver Nowack to his father Hans. The modifications are warrantied for a full year and can be retrofitted to any existing M5, and since the upgrades have been carried out principally on the engine itself, can also be fitted to its two-door counterpart, the M6. Details in the press release after the jump and photos in the gallery below.

Nowack Motors N635S 5.8 "Hans Nowack Edition"

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.

      let me guess, bored, completely re-worked heads, new cams, pistons, rods, lighter flywheel, and redline raised. basically a completely new build on the same block. that is a huge jump in power, or the 'stock' v10 is just choked.

      Man, I know that joint. They filmed some post-apocalyptic SyFy show there one time.

      I can't believe some of you are complaining about more horsepower! If you don't like the motor or the car, give it to me, I'll take care of it for you. :)

      what a ghetto-fied M5. sad.
      • 4 Years Ago
      Hey AB, can we get a tag for 'tuner special edition' posts so we can omit them? I am guessing I am not the only one who just doesn't care about this sort of thing.
      • 4 Years Ago
      Because 500 wasn't enough? Tuners confuse me.
        • 4 Years Ago
        what the hell is up with those rims? don't fit the car one bit.
        • 4 Years Ago
        Neither do those black vinyl-wrapped brake duct surrounds. This thing is a whole lot of mess. It's hard to mess up a nearly perfect machine like the M5, but mission accomplished Nowack.
      • 4 Years Ago
      That's a huge jump for modifications that don't include forced induction. I'm a little skeptical, but if it's true, that's quite impressive. Especially if it maintains good drivability characteristics.

        While this car visually screams "tuner" which seems to have a lot of people turned off (myself included), you gotta admit it takes a good amount of experience and knowledge to pull that kind of power out without FI. Do this again with stock exterior, KW set-up, and BBS's and they'd get a much better response.

      OMG another wheel fail from a tuner
      • 4 Years Ago
      Sweet. That's what I'm talking about. Crazy NA power.
      • 4 Years Ago
      Don't you guys read the article? You can just get the engine mods.

      To some, there's no such thing as too much power...not that most people are even capable of using the full potential of power that the current M5 puts out in stock form.

      What I'm not sure about is what their designers were thinking when they went ABS grey on the front bumper air ducts. It just gives the whole front end/face an awkward look. The wheels are just silly looking and that red roundel on a white car pretty much nails down the clown effect And then there's the blacked out top...the whole thing is 'change for the sake of change' rather than to make it look better. Two thumbs down from me...not that it matters.

      People are stupid for disliking tuners. In this case, however, the car is quite ugly.
