Ilmor motor, 226g/kw-hr (0.37 lb/hp-hr)

Best efficient production auto otto
225 g.kw-hr (0.37)

Wright R-3350 compound aero engine from 1940
0.4 lb/hp – hr

VW V8 Turbo Diesel (yr 2000),
205 g/kw-hr, (0.33)

Audi 2.5 l TDI, 198 g/kw-hr

Volvo diesel truck engine,
188 g/hp-hr

Because of the expense and complexity, and because there is no demonstrated fuel efficiency advantage, I would say the Ilmor motor is a dead end.
