Despite putting out (some) power, the engine in this little Volkswagen Golf in Poland has one of the lowest operating temperatures of any out there, at only 98.6° Fahrenheit. Also, it appears to be fueled by cheeseburgers.
How many cylinders you think it's got? I'm thinking it's the abandoned W18 that we saw in the original Bugatti Veyron concept, the 18/3 Chiron.
I have no other guesses.
