I bet its the sump that is A4 size !
I have seen pictures of it as fitted to the US Ford Bronco, a bit like a UK Freelander, and it there isnt much room left in the bonnet.

Some interesting guff on it here : https://www.team-bhp.com/forum/tech...-5l-3-cylinder-dragon-petrol-engine.html

Standout facts in that thread for me were :
The crank centreline is offset from the pistons to reduce bore wear and friction , sounds interesting.
The accessory drive belt dips in oil to reduce friction and noise, sounds horribly familiar as a fix to an issue ?
