BMW F30 / F80 M3 test mule SPIED

With the E90 wrapping up production soon and with plenty of F30 spy shots going around it was only a matter of time until the F30 M3 was spied. The test mule pictures show the usual M upgrades including: 19" sport wheels, larger cross drilled rotors and multi-piston calipers, and a quad exhaust. This looks like standard F30 body work for now. The final M3 will sport wider front and rear fenders with much of the body work being made out of fiber reenforced plastics for weight savings.

The M3 is rumored to be powered by a tri-turbo 6 cylinder in either an inline or V configuration. The large displacement 8 cylinder engine is being dropped for fuel efficiency requirements.

Check out the pictures and then let us know what you think - http://www.autowereld.com/spyshots/d...?artikel=11989

Wait a minute....Hasn't everything we've heard about the new M3 been saying 2 door ONLY? That sure looks like M3 tailpipes on a 4 door....

I believe that was just a rumor. Of course you could argue that BMW M is simply using a F30 sedan to test rough power plant and suspension options to get a jump start on the coupe development. That being said I think if they let a test mule be caught in such obvious M clothing it means we will see a production M3 sedan.

Maybe the concerns about taking away M5 sales didn't happen? Or with the new M3 coming with a turbo six it allows them to position the M3 as the lighter sporter car to the grand touring luxury V8 M5?

Who knows....all I can say is that I think a M3 sedan is coming.

I like it. Right after mine was built I was walking into a Starbucks and there was a new M3 in the drive through. If mine had not already been on the water I think I would have canceled and ordered the M3 Sedan.
This one is my 8 th BMW and I think I should treat myself to an M one time before I get to old to enjoy it.

Oh, oh..........I hear voices saying too late, too late. I didn't want to hear that.

I see Scott (BMW insider) has said the next M3 will use a tri-turbo inline six and not a vee six as rumoured. Why would BMW want to make such a complexied system, two turbos could easily achieve the desired output levels and is tried and proven technology, plus it much be lighter overall what with much less plumping. I think I will steer clear of the first year's product until I see how reliable this technology proves to be.

BMW would be foolish if they decided not to make the F30 M3. All BMW's prime competitors, Lexus, MB and Audi, will bring 4-door-M3-equivalents (IS-F, C-AMG, RS-4), and BMW doesn't want to be left out.

Primary reason for tri turbo - eliminatng turbo lag.

Why, is the lag that noticeable in their bi-turbo applications?

Just sounds like they are over complicating things but since we are talking at M-Division I will hold my tongue until I test it myself, but I still would wait a year or so before buying one just to see how reliable it was.

Definitely - there is a turbo lag in cars with N54 and N55 engines. I had two E92 335i - '07 and '09, both with 6 MT. Comparing it to my current car - '11 E93 M3 6MT - there is world of a difference in throttle response, mostly due to turbo lag.

I'm not worrying about reliability - that's what the warranty is for.

Well compared to the masterpiece that is the S65 engine then I have to conceed there is indeed lag but it's not dreadful compared to what is normal for FI engines, the only one better that spring to mind is Audi v6T and it's supercharged. And yes a warranty is there to catch all the early teething problems but I can't think of too many things worse than buying a new car and can't drive it because it's in the shop getting sorted it. So I personally will wait and see how things unfold.

Since we're talking M3 here, S65 is the benchmark for the new engine.

I wouldn't worry about first year reliability. If there are any problems, they're usually sporadic, if you take the current M3 as an example. They're easily overcome by the joy of driving a new M3
