The BRZ was designed around a flat 4, which means it's not going to accomodate an engine that's about twice as long and significantly taller. Neither is it going to accomodate the long hood/short deck body proportions of BMW Z models, because the A-pillar is almost a foot further forwards.
Actually, I remember reading that the FT86 chassis is a Modular one that Toyota had planned to accept Both Inline 4's and V6's in future use, one being the IS replacement, and another being a small Toyota based sports sedan. Engine hard points are actually some of the easiest to modify.

Mechanical CAD software makes it relatively easy to scale an existing design into something that is longer, wider, or both. Since it is likely that a joint product co-developed with BMW will be built at a non-Subaru facility, they would have to retool another factory anyhow. It is more reasonable to expect that they would keep some of the overall desirable BRZ/GT86 architecture features that would be suitable for a larger platform.

That's what I thought at first, but if you think about it, a V6 makes it easier to keep more of the engine behind the front axle when compared to an I-6, while still allowing adequate room for the suspension and the steering column when compared to a flat-6.

I wish they would wake up and realize I-6 is probably the best engine config out there. 12 is nice too, but way too many parts for good reliability. I-6 is perfectly balanced and still fairly simple, and they had it mastered. I'd love a new lower displacement I-6 with DI (maybe FI too, but bmw has always been NA kings). However I agree, not likely if this is going to be the chassis.

The I6 is great for balance and smooth power delivery, but sucks for packaging. I personally love a long hood and short rear look and the song of a good I6, but I also understand why almost everyone has gone to a V formation.

Maybe because the chassis is just THAT brilliant?

It's not the engine nor the suspension that makes this car be what it is, it's the chassis that Toyota and Subaru may have come up with; something so brilliant that it's cheaper to get into a joint venture, than to have to reverse engineer it and not get it completely correct (lost in translation).

Or maybe it is just a good chassis that is easy to modify.

That's completely false.

Looks like the convertible is a reality.

Whoops, just posted a thread of this. Eh, I'd say it deserves a thread.
