Basically a Mercedes article but as mclaren runs the merc engine it could go in here.
Not much of a 'revelation' I heard about the shaft running through the vee of the engine some time ago.
More interestingly is the aero benefits, it's simple mclaren just need to make the side pod openings smaller and as we all know that will improve airflow to the rear, easy....
Could mclaren bring their gearbox forward for abetter balance with the chunky suspension arms?
