Would that be the MGUK sitting alongside the ES? Blurry cylinder. It would allow placement of that mass ahead of the ICE while keeping it as low as possible, rather than stacking it atop the ES.
Motor infront ICE timing gears will never happen, same for from rear. All experiment (Honda concept, F14T) that were done in those direction were futile and dint bring any real benefit. Each side of crank is hugely air starved and void space. Hence makes sense to fill in those space with heavy ICE ancillaries.
Current KERS , sump pump ; exhaust geometries complement each side of cylinder bank. Especially at 90deg ICE BANK ANGLE. Furthermore we dont have any real possibility to change and undercut monokok width to gain any advantage with such system. I woudl argue polar moment of inertia its lowest in optimised legacy configuration.
C5.18.3 — MGU-K (MGU-K Mechanical Power Connection)
“All mechanical power to and from the MGU-K must pass through a single shaft to the MGU-K transmission. The connection to the ICE crankshaft must be ahead of XPU=100.”
This rule mandates where the MGU-K must connect mechanically to the ICE crankshaft — specifically that that connection point lies in front (in the positive XPU direction) of the defined reference plane XPU = 100.
XPU coordinates are part of the PU coordinate system defined elsewhere in the regs, used to standardize where major PU elements are placed relative to the chassis and each other.
