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.

5kg is equivalent to 5L. This Audi can travel up to 500km using that little fuel? Wow!
Or could be there any typo? *just curious*
Compressed pure hydrogen leh.
5 kg is not 5L. The amount stored depends on the pressure and tank volume (cause pressure affects the density of hydrogen since it can be compressed).
5kg = 5 liter is for water. What is the specific gravity for compressed hydrogen?
how I wish I can have an Audi one fine day… :)
It’s the refueling process that is crucial. It takes anywhere between 5 minutes to eternity depending on the pump pressure and also how much pressure the car’s tank could handle.
How much would a 5 kg hydrogen fuel cost in dollar and cent?
If mankind can make much progress in this technology, it would be a major leap forward to… err, what’s bigger than mankind?
Nice car compare to Accordana
700 bar? wohohohoh who would like to sit on the tank stored with gas at 700 times atmospheric pressure.
Paul, is the figure correct?
imagine if the roads are filled with fuel cells cars, terrorists will be so damn happy.. lol the entire city can go BOOM.. or if you don’t mind riding a moving bomb ..
