He's wrong in saying that this block is from the s55, the intake is not from the s55 and the various coolers in the front are no accurate. There's an engine oil cooler located on the right side of the car and an additional water cooler on the left.
His facts are all wrong yet he's suppose to be a journalist.

The block is made from the same casting as the s55. The only difference between the S55 and this block is the LDS in the S55 whereas this still uses the cast in iron sleeves. Aside from that, they are both closed deck blocks that share absolutely everything such as dimensions and the aluminum alloy. There would be no point to make this motor entirely separate from the S55 when they can just add the sleeves/LDS after the basic casting process is done. The s55 and this motor share their pistons, however the first piston ring is different to account for the gray cast liners vs the LDS. I got all this info from the M2's technical document. They dont really go into detail about the rods and crank.
