  • Expertise in fuel cell technology – A7 Sportback h-tron quattro technology demonstrator ready for real-life traffic
  • Long range – more than 500 kilometers (310.7 mi)
  • Plug-in hybrid concept can and electric quattro

It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h tron quattro uses a powerful, sporty electric drive with a fuel cell as its energy source, in combination with a hybrid battery and an additional electric motor in the rear. Its drive configuration makes the emission-free Audi A7 Sportback h-tron quattro a quattro through and through, with 170 kilowatts of power at its disposal – a new departure in fuel cell cars. There is no mechanical connection between the front and rear axles. As an e quattro, the A7 Sportback h-tron quattro features fully electronic management of torque distribution.

To coincide with the Los Angeles Auto Show 2014, Audi is inviting international motoring journalists to drive their first few test kilometers on public roads with the technology demonstrator.

“The A7 Sportback h‑tron quattro is a genuine Audi – at once sporty and efficient. Conceived as an e‑quattro, its two electric motors drive all four wheels,” explained Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. “The h‑tron concept car shows that we have also mastered fuel cell technology. We are in a position to launch the production process as soon as the market and infrastructure are ready.”

In the fuel cell mode, the A7 Sportback h‑tron quattro needs only about one kilogram (2.2 lb) of hydrogen to cover 100 kilometers (62.1 mi) – its energy content is equivalent to that of 3.7 liters (1.0 US gal) of gasoline. The tank capacity means it is capable of a range of more than 500 kilometers (310.7 mi).

Like a car with combustion engine, refueling takes no more than around three minutes. The range is boosted by up to 50 kilometers (31.1 mi) by a battery with a capacity of 8.8 kilowatt‑hours, which is recharged by recuperation or alternatively from a power socket. As a plug-in hybrid, the A7 Sportback h‑tron quattro will thus have crucial extra range in reserve.

It sprints from 0 to 100 km/h (62.1 mi) in 7.9 seconds and on to a top speed of 180 km/h (111.8 mph). It covers over 500 kilometers (310.7 mi) on one tank of fuel – and its exhaust emits nothing more than a few drops of water: The A7 Sportback h-tron quattro, which Audi is unveiling at the Los Angeles Auto Show 2014, uses a powerful, sporty electric drive with a fuel cell as its energy source that operates in combination with a hybrid battery and an additional electric motor in the rear. The overall electrical system power of 170 kW is transferred to both the front and the rear wheels. This drive configuration makes the emission-free Audi A7 Sportback* a quattro through and through – a new departure in fuel cell cars.

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.
