If your like me and a big fan of BMW’s motorway crushing 5.0-litre V10 engined M5, you will be as sad as I am to see it leave. BMW is changing the V10 in a bid to be more environmentally conscious and replacing it with a twin-turbo V8.
However, to keep our dreams alive Nowack Motors has stepped up to give the big normally aspirated lump a final farewell. Oliver Nowack has retuned the engine and dedicated it to his father Hans. By adding a new set of intake air collectors, a re-flashed ECU and a bit of massaging to the engine components, Nowack has produced the N635S 5.8 Hans Nowack Edition.
These modifications see the standard M5′s horsepower increase from a more than ample 507, to an absolutely incredible 708 hp, and yes you did read it right 708 hp ! To make it even more exciting, all the modifications are able to be retrofitted to any M5 and even the M6.
With this sort of power could this be the ultimate M5 ? To read more about this incredible car and to see the full press release check out Autoblog.
