This was my vote also.

4 liter, twin turbo, 520hp, 480 lb-ft torque.

That was absolutely my first complaint, besides the car being really really slow.

The FoV for this on an m4/3 would almost certainly be narrower than it is on an 8mm APS-C camera.

The DoF on a 8mm lens is huge, even at the largest apertures this lens can do. Focusing should not be an issue at all really.
