I love how the comments look and sound the same whenever we see a new mule on any BMW car. There are people that say "Wow--this is gonna be awesome" and people who say "This looks and sounds like shit!"
It always makes me laugh because you are talking about a product that is on step 5 of a timeline that has 1695832 total steps. We really have no idea at this point, especially based on the video that was attached.
A few things that I would bet on for the next generation M3--it will have more power, it will get better gas mileage, and it will be FI. And, it will be a great car to drive. Like previous M3s, differences be damned. The details, however, will be sorted out over the next 2 years
I read these threads for the entertainment, nothing more.
