It’s almost as if a whole bunch of car manufacturers made a pact to bring out hydrogen fuel cell concepts this year to gauge public reaction to the technology.

This is the new Audi A7 Sportback h-tron quattro, which is an electric car that can be powered by both a hydrogen fuel cell or a lithium ion battery that can be recharged in four hours with a 230V domestic socket, or two hours with a 360V industrial socket.

Powered by the battery, it has zero emissions. Using the fuel cell, it’s only emissions are water vapour. A full 5kg tank of hydrogen stored at 700 bar can take it 500 km, which is almost comparable to a full tank of petrol. The battery has a 8.8 kWh capacity adapted from the A3 Sportback e-tron and the charge allows up to 50 km of travel before the fuel cell has to kick in.

There are motors at both the front and rear axles, giving it “e-quattro” ability. The motors can produce a total of 540 Nm, taking the 1,950 kg concept up to 100 km/h in 7.9 seconds.
