The 2010 Nowack Motors N635S 5.8 Hans Nowack Edition is a proud son-to-father tribute. The late Hans Nowack was a technical expert on world-class engines and was the expert behind ECU-tuning. Oliver, his son, dedicated his masterpiece – the N635S 5.8 -- in memory of his father. The peak power output is 718 hp at 9000rpm.

Nowack Motors, manufacturer of high-performance engines, has equipped the N635S with two intake air collectors that offer increased air volume. The color of the vehicle matches the paintwork color of the said collectors.

Truly a unique and perfectly engineered product, the N635S 5.8 Hans Nowack Edition is at the zenith of naturally aspirated engines. The upgraded BMW M5 marks the retirement of the 5.0-liter V10 engine. With the N635S 5.8 Hans Nowack edition in place, the car can produce 708-hp and run from 0-62 mph. M5 and M6 models can be converted into the N635S 5.8 Hans Nowack Edition.
