Audi is also examining the potential offered by fuel-cell power systems – technology on board the Audi Q5 HFC, a technical study. The letters “HFC” stand for “Hybrid Fuel Cell.”
The concept car relies on synergies and consequently utilizes many technical components from the future hybrid models. Two high-pressure cylinders store hydrogen at a pressure of 700 bar. The polymer electrolyte membrane (PEM) fuel cell outputs 98 kW (133 hp). The lithium-ion battery has an energy content of 1.3 kWh. The drive is provided by two electric motors close to the wheels; together the motors produce a combined peak output of 90 kW and up to 420 Nm (309.78 lb-ft) of torque.
