Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

EVO takes flight in BMW's sultry i8

Electric cars and hybrids are here to stay, much to the apparent dismay of some auto enthusiasts, but that doesn't mean they have to represent the death of enjoyable driving. Granted, the initial run of hybrids in the US like the Honda Insight and Toyota Prius weren't exactly tailor-made for aggressive folks behind the wheel, but things are clearly changing. In its latest video, Evo takes a look at three examples from Europe's new crop of electrified vehicles to show that the future of fun motoring is safe and sound.
Evo editor Henry Catchpole kicks things off with one of the most bizarre EVs of the bunch, the tiny Renault Twizy. Its low power and 50-mile-per-hour top speed might make it miles away from a hot hatch, but there's still fun to be had in extracting the most from this little city car. Next up is the Audi A3 E-Tron, which isn't technically available yet. It's a step in the right direction of eventually creating an affordable, fun-to-drive hybrid hot hatch.
However, the main event is Catchpole getting some seat time in the BMW i8. The Bimmer can really fly -literally in this case - and the butterfly-door coupe offers a clear look at the prospects for electrified sports cars. It might not have the power of hybrid supercar contemporaries like the LaFerrari or Porsche 918 Spyder, but the BMW doesn't cost nearly as much, either. See? Improved efficiency doesn't have to mean boring.

Audi to abandon CVTs?

The continuously variable transmission is one of those technologies that seems to make a lot of sense on paper, but in reality, almost always numbs the driving experience. That's one reason why Audi, according to reports, is planning to phase them out.
One of the first automakers to implement use of the CVT, Audi mates CVTs to larger engines than many other manufacturers, which typically install them on scooters, hybrids and small-displacement hatchbacks. But the time of the Audi CVT (which it calls Multimatic) may be near its end as a report from Australia indicates that Ingolstadt is moving toward a two-gearbox lineup that does not include the rubber-band transmission.
Instead, Audi is said to be focusing its attention on the S-tronic dual-clutch transmission and on conventional torque-converter automatics - although the development of beefier DCTs could spell the end of the Audi slushbox, as well. We've reached out to Audi for comment, so watch this space for confirmation.
