4.0 Liter engine (natural Aspirated) , V8 400hp ( M3 new engine)

In the February 2005 issue of Roundel, Bob Roemer (broemer@roundel.org) writes the following:

" And now for Z news: BMW M has reversed its earlier proclamation that it would not produce an M version of the Z4 roadster. The new M roadster will use the M3's 400 horsepower, four-liter V8 engine and will debut sometime next year."

i read somewhere on bimmerforums.com that the V8 might be 3.6 or 3.8 liters instead of 4.0. I also read on bimmerforums.com that bmw might just cancel the V8 and use a new I-6. I hope they use a V8 though, then bmw owners cant say "bmw makes so much power out of the I-6 blahblahblah"

man if bmw made a 400hp 3.6/3.8liter I-6, amg owners would never hear the end of it. omg......

Well if I hadnt of read it here I would never have heard it in the first place.

A V8 in the z4 who cares, its still a butt ugly car

Don't be surprised if output of the M Z4 engine is down some from the same engine in the sedan - restrictive exhaust routing, etc.

modified z4 looks ok! with hardtop

Yah, now if they could change the hood and widen it a bit, and ...
