It will be interesting to see how close your predictions are to reality.

Since this is a thread for speculation, I will go ahead and speculate that the power will be 460 hp.
Sure.

I think my post is slightly better than "speculation" isn't it. I'd give it educated guess or hypothesis at least.

Now to the weight, the new BMW's did not get weight reduction, but just less weight growth. Only the X3 is 30 kg lighter than the previous generation. In this way we can expect the 3 Series F3X to get about 50 kg lighter. This would mean a 335i F30 would weight 1550 kg (EU) compared to todays 335i E90 that weighs 1600 kg (EU). If the M3 F32 is based on a TT I6, and not a havier NA V8, it will weigh 1550 kg (EU), what is 100 kg less than todays M3 E92, and it would be slightly less than the previous M3 E46.
Thanks. Those numbers look quite reasonable to me. Do you have some real evidence of these F series weights or just guesses/educated guesses?

A major consideration of engine configuration is the engines balance and efficiency. Cross plane V8s like the M3 are naturally quite balanced. V6s are both poorly balanced thus require extra gear driven balancing and are less efficient than I6 because of that and the entire extra head and valve system. Since BMW has had no production engines ever in this configuration it is extremely unlikely. I6 is the most efficient and balanced engine configuration around. The only real drawback is its long length, making it typically unsuited to a FWD application.
