2014 Audi A7 Sportback h-tron quattro

The “h” in the name h‑tron denotes the chemical element hydrogen. In visual terms the technology demonstrators that Audi has brought along to the Los Angeles Auto Show basically resemble the production models. 

As the label with the h‑tron signet reveals, this concept car now takes its place alongside the other Audi models with alternative drive principles, the e‑tron and g‑tron. Externally, there is no other evidence of the fuel cell that converts hydrogen into electrical power on board the vehicle. 

Driving in the Audi A7 Sportback h‑tron quattro offers the full appeal of electric drive in conjunction with the new e‑quattro. The silent propulsion is fully available from the off, and the fuel cell reaches its maximum output within one second at full load – a more dynamic response than a combustion engine because the entire drive system involves only a few mechanical components.

With 540 Nm (398.3 lb‑ft) of propulsive power at its disposal the Audi A7 Sportback h‑tron quattro, which tips the scales at only around 1,950 kilograms (4,299.0 lb), races from a standstill to 100 km/h (62.1 mph) in 7.9 seconds. 

Its top speed is 180 km/h (111.8 mph) – a top figure for its field of competitors. The e‑quattro concept requires precise coordination of the electric motors – the technology demonstrator offers a sporty, stable and high-traction drive that is comparable to a production car with mechanical quattro drive.

The four hydrogen tanks of the Audi A7 Sportback h-tron quattro are located beneath the base of the trunk, in front of the rear axle, in the center tunnel. An outer skin made from carbon fiber reinforced polymer (CFRP) encases the inner aluminum shell. 

The tanks can store around five kilograms of hydrogen at a pressure of 700 bar - enough to drive over 500 kilometers (310.7 mi). According to the NEDC cycle, fuel consumption is roughly one kilogram (2.2 lb) of hydrogen per 100 kilometers (62.1 mi) - an amount with an energy content equivalent to 3.7 liters (1.0 US gal) of gasoline.

It is already the case that the A7 Sportback h-tron quattro always travels with zero local emissions. By using the renewable fuel hydrogen, it can also be used globally as a zero emissions vehicle
