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.

It's difficult for Ariel to come up with a mid-life refresh for its cars - there simply aren't that many bits to fiddle with in the first place. Still, the boys from Somerset must have succeeded, because what we have here is the freshly updated Ariel Atom 3.5. As the name suggests, it's a development of the Ariel Atom 3, with a crop of minor visual  tweaks and some mechanical changes too, keeping Caterham and BAC looking over their shoulders.

But that’s no surprise when it comes with a very agreeable 270bhp to play with – enough to push the RCZ R to 62mph in 5.9 seconds – good looks and decent economy. But Peugeot has a whole selection of RCZs lurking below the R, so as it’s obviously time to garner some attention for the R’s lesser siblings we get a limited edition RCZ to bump up sales and footfall in Peugeot showrooms – the Peugeot RCZ Red Carbon Limited Edition.
