I think I read a post somewhere where a Ferrari V12 engine can be slipped sideways into the space where the ICE and IMA were fitted if removed. There would be some handling problems but it should go well .....if you live at the top of a steep hill!

Reminds me of the old story of the two friends climbing in the Alps above a deep crevice the uppermost looses his footing and his companion calls out "are you alright"? as his friend, falling at speed past him, manages to call out "yes fine......... so far"!
