This one is a sort of hybrid, with a gasoline heater onboard to heat up the air at speeds above 35 mph. With 8 gallons of gasoline it has a range of 800 miles. The onboard compressor recharges the air tanks in about four hours, using AC electricity. Pressure 4,500 psi. It is unclear how far it will go, at what speed, on compressed air alone. (Unclear to me, that is.)
