I think it is a case of death by a thousand cuts, the surface area of the bearings is quite small, presumably for packaging reasons when they designed the motor, there is a very small tolerance between the bearings and crank, the motor happily revs to over 8k rpm, the condition based servicing has the oil changes out to 20000km intervals, and it is a naturally aspirated 500 hp motor built to a price point set by company accountants.
Also, because it has 10 cylinders and a seven speed gearbox in a North - South orientation and the letter S and numbers 8 and 5 in its name it has terrible feng shui. I believe it can be improved with mirrors... ?
