its pretty much impossible to tell how much fuel its burning by sonic analysis because the sound changes by varying exhaust layouts and even atmospheric conditions. There would bee too much inconsistency, plus a system that can track 24 cars at the same time in different parts of the track? Not even in star wars
They do use Sonics actually and its very straight forward.
Its very easy to take a sample of the sound an engine makes at peak revs and a sample of the engine noise when its on tick over in the pit lane. Say for arguments sake that the tick over pitch of the engine is a low C and at max revs the pitch hits a Hi F, the time it takes to ascend through the pitches relates directly to the weight of the fuel being carried as the labor on the drive trains differs under different fuel weights. Simples!
