WHEN it comes to transportation, most manufacturers are in on one form of electric propulsion or

Nissan envisions the pure car as the future (the Leaf), General Motors favours the electric car as is typified by the Chevrolet But, ultimately, it will be the cell-powered vehicle that solve the environmental headache by the consumption of fossil fuels.

believes the electrification of the automobile is the route, but only as long as the needed to recharge the main or create the hydrogen that feed the fuel cell from a sustainable, renewable

The Audi Balanced Mobility includes an in-depth lifecycle that looks at not only the consumed in the production of a new car, but the fuel consumed over its life and the environmental cost of the vehicle when its day is done.

It’s a logical way of determining the of the environmental footprint (smog and rain) and the greenhouse-gas emissions the automobile emits on a cradle-to-grave The production and subsequent use of any form of transportation must use clean sources and ensure that the consumed throughout the lifecycle is as efficiently as possible.

Consider the new A6. The approach comes together in a of ways. Mass reduction new A6 is 80 kilograms lighter than its counterpart) allows a smaller, fuel-efficient engine and a smaller gas without affecting either or the per-tank driving range.

in aerodynamic improvements and you end up with better fuel economy the new A6’s average fuel drops from the outgoing 7.1 litres per 100 kilometres to 6.0 L/100 km.

This work touches one of the Balanced Mobility philosophy. The part of the initiative is both and points to the way future fuels reduce the environmental burden by transportation.

The problem with the of the automobile is that not all electricity is equal. The environmental toll it depends very much on how the that’s needed to recharge the battery is produced. Sadly, it patently obvious that, the electric car is emissions-free at its tailpipe, it can be but if the power it consumes is not produced in an friendly manner.

To put things perspective, it helps to compare the footprint of a regular gasoline-powered sedan with the footprint of a sized electric car and the electricity it

In Norway, for example, the electric car leave a significantly smaller footprint than its gasoline-powered because 99 per cent of the country’s supply is clean, hydroelectric The same electric car driven in however, would leave a larger environmental footprint in its than its gas-powered cousin 77 per cent of the country’s electricity is by coal-fired generation.

Obviously, the electric solution lies in the use of energy.


Audi’s clean-energy is to make hay when the sun shines or, more accurately, when the blows. The company has invested in wind turbines that are of a wind farm in the North Sea off the coast. On an annual basis, the turbines produce enough to satisfy the needs of a town of people.

If all goes as envisioned, the electricity when the wind blows, a and renewable resource, will be in one of two ways — down the it will satisfy the need to an electric car such as the mighty e-tron, or the electricity will be to power an electrolyzer. The latter water into its constituent — the oxygen is bled off to the while the hydrogen is stored for use. Again, the hydrogen has two uses. When the fuel finally comes of age, the will provide the fuel to produce the electricity consumed by the car and its motor. In the near term, it will be mixed with dioxide, which is harvested the atmosphere, to create synthetic gas (methane).

Audi calls it e-gas.

The of electricity into a readily medium allows it to heat or be used as a source of automotive To this end, Audi launch a turbocharged natural (TCNG) version of its next-generation A3, will hit the road in 2013. It be joined by a TCNG version of the A4 a later.

The use of wind or solar to create an automotive fuel, be it the needed to recharge a battery or the that will fuel natural gas-powered vehicles, is an way of making the best of a bad situation. there is a compromise when is converted into hydrogen process is around 60 per cent and so there is some power in the conversion process), but it’s sort of thinking that solve a moral dilemma and the way to a greener automobile.
