I'm certainly no expert but that was my first thought as well. The s65 v8 shares the same architecture as it's s85 v10 brother. As with the s65/s85 you'll need to make a number of changes but in the end you can imagine you'd be left with one hell of a v6. You'd have a lot more space left [vs an i6] for the plumbing of tri-turbos.

Tri-turbos make sense to prevent lag & it should do an amazing job at that. Among others, Merc had a tri-turbo v6 at the '05 Geneva auto show that was very impressive. It never made it to production due to cost. BMW is also rumored to be announcing tri-turbo configs to outfit the x5 & x6 this fall. In closing I think this is very plausible & would address everyones concern regarding throttle response/lag in the next F3x M3.

Keep in mind that a lot of the characteristics that make BMW's i6 amazing can become less important when adding FI.

In the end, if true, I do see the foundation for a high revving, almost lag free monster.

BTW: Feel free to chime in on the characteristics, pros & cons of an s65 derived v6 variant, etc.
