This 1:1 Cardboard Model Of A BMW M10 Engine Is Amazingly Detailed

Marc W. Zak is a man with a kind of patience that makes the mind boggle. And a lot of skill. He created this incredible cardboard 1:1 model of BMW’s legendary M10 inline-four (the real version perhaps most famously used in the 2002 Turbo) over the course of a year, and the detail is astonishing.

It even includes all the internal components it should - the crank, the con-rods, the pistons, the camshaft - they’re all here. Much of it even functions to a degree - at one point you can see the crank being turned at the pistons going up and down as a result.

We are in awe!
