Motor V8 400CV
"This rip-roaring prototype is the long-awaited Z4M, which Autocar´s spies say shares its V8 engine with the upcoming M3. The car will have the task of lifting the image of the whole Z4 range, especially with an all-new Porsche Boxster just gone on sale. The Z4M is also BMW´s riposte to the new Mercedes SLK 55, which has a 355bhp (non-supercharged) AMG-fettled V8 engine.
There´s no news yet on whether the Z4M will have the V8´s full 400bhp. Although it would be a logical move, this sort of wallop would make it hugely more powerful than any rival (the new Boxster S has just 276bhp) and almost as grunty as today´s 911 Turbo.
The car undergoing tests here at the Nürburgring circuit is distinguished by the classic quad exhaust pipes, new wheels and a revised suspension set-up."
