CAR tech: Audi's miracle e-fuel (2013)

Global warming; sky-high oil prices as reserves peak; spiralling crop prices and intense pressure to find fertile land – society faces immense challenges, as it strives to protect the planet and keep our cars on the move. Audi is working on a miracle fuel that could help mitigate these problems, in a facility under construction in the uncompromising, scorching environment of New Mexico, USA.  Not content with having a range more diverse than London’s World Pride parade, Audi is moving into the fuels business, in partnership with US biotech firm Joule Unlimited. The pair are developing carbon-neutral synthetic fuels, called e-fuels in keeping with Audi’s E-tron eco brand.

Designed in Italy, Engineered in China

"The soul of our designing is in Italy," said Silvio Petro Angori, CEO of Italian design house Pininfarina S.p.A. "We will do all styling in Italy – we will not do that in China." But in order to cater to the growing number of contracts from Chinese automakers, Pininfarina will soon begin engineering and product development in China with a center in Shanghai's suburb of Anting. Pininfarina has been working with Chinese automakers since 1996.
