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
