Audi at the Los Angeles auto show presented the A7 Sportback H-Tron Quattro Concept. The hydrogen prototype car is described as “technology demonstration” and can travel more than 500 miles with just a tank, producing only water instead of CO2 emissions.
The drivetrain of the Audi A7 Sportback H-Tron Quattro Concept uses a hydrogen fuel cell, which in combination with an electric motor at the rear, produce 230 hp with 540 Nm of torque, with the 0-100 km/h being completed in 7.9 seconds, having a top speed of 180 km/h.
The system has two modes of operation, either only with the hydrogen engine, or by using both the hydrogen engine and the electric motor. When only the hydrogen engine is used it requires 1 kg of hydrogen per 100 kilometers, the car can travel 50 miles on just the electric motor. The batteries charge either with energy recovery during braking, or via a socket. The exhaust is made of plastic, to reduce the weight and also because the only thing that passes through it, is water vapor.
The hydrogen engine can operate from temperatures of -28 degrees Celsius to 52 degrees Celsius, with the refill process of the hydrogen tanks to take just three minutes. At the interior the tachometer has been replaced by a power meter, while at the dashboard there are instruments that show the level of hydrogen in the tanks and the battery charge level. The center console has an EV button that when you press it, it allows the car to move using only the electric motor.
