As demand for individual mobility rises, so does consumption of natural resources like fossil fuels. But oil and gas are not in unlimited supply, and they pollute the environment. There's no shortage of ideas for environmentally friendly engines, but it doesn’t look like the car industry has a plan for radically reducing CO2 emissions any time soon.That is why Audi is pursuing numerous strategies. They include advancing the development of conventional engines while also working on plug-in hybrid powertrains that combine conventional combustion engines and electric motors. Audi's latest research model A7 h-tron quattro also operates on electricity, by making use of fuel-cells.
