Paul and others - this looks like simply the old GMC two stroke Diesel
with
the exhaust and scavanging
ends swapped nothing to support claims of great perf increase - low cost -
simplification nor
light weight.
Incidently I hear that an Audi Diesel ALMP2 won the 12 hour race overall

Correction - it is a LMP1, and there is a great writeup on it in April Road
and Track.
