Aunty Entity Jet Car

In the movie “Mad Max Beyond Thunderdome” Aunty Entity drives a custom vehicle appearing to be powered by both combustion engine and a turbine engine.
The original concept art by Ed Verreaux reveals that the vehicle was to have twin supercharged engines and twin turbine engines. The design was downsized and modified for the movie. Only one turbine engine was ultimately in the vehicle and one functional combustion engine.
