Right before BMW announces the new BMW M5, Nowack introduces a small upgrade for the current M5.
We’ve already seen Nowack do the Cooper S, X5m and X6m and now they took care of the E60 M5.
They already did the M5 and called it the N635S with 635bhp but to honor the current M5 and give it a proper goodbye, they introduced this special limited edition: ‘The N635s 5.8 Nowack Edition”
The modified 5.8 liter V10 engine now throws out 718bhp at 9000rpm.
