I agree that the OP could be correct with the heatsoak issue. Anyone dismissing this as impossible is either:
A) not accustomed to hard driving in the heat -or- B) putting way too much faith in the cooling properties required for how hot our motors get. Remember when BMW overlooked the oilcoolers on the first 335i's?

I'm not saying this car is doing it, nor am I saying it's not, but we haven't exactly been in the hottests months yet either.

A final note to the M3 vs 1M topic,
If saying that the drop-off of TQ or HP after multiple hotlaps is "underwhelming" then would that not be a miniscule point compared to never being able to push an M3 into it's highest level without being on a closed track? I have had 2 friends that loved thier E92's in Germany, but sold them as soon as they got here because they just couldn't find anywhere to "open them up".

To me the 1M is a no-brainer. But, to each their own.
