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.

2016 Audi TTS

We recently drove the Audi TT, and although we wish it were radically entertaining instead of merely very fun, it's nevertheless a sharp coupe that vaults ahead of its predecessor with an inspired interior and eager handling. That car will be precursor to this TTS when it gets here a year from now, with the TTS adding adjectives like "more" and "better" to just about everything found on the base coupe. With the standard car having already put on such a fine edge, we wheeled the TTS on Spanish roads and at the Ascari race track to find out how much better and higher-performing the S will be.
Driving Notes
As of this writing, today's TTS commands an $8,350 premium over the TT. Assuming a commensurate gap is carried over into this next generation model, that supplemental dosh will get you 310 horsepower and 280 pound-feet of torque instead of 230 hp and 273 lb-ft in the standard TT. That would mean more for your money, too, since the gap between the current TT and TTS is 54 hp and zero lb-ft of torque. To achieve the new numbers, the 2.0 TSFI engine from the TTS benefits from upgrades like sturdier valves, revised aluminum pistons and stronger connecting rods with new bearings, a reinforced crankshaft and a high-performance intercooler. The amplified brawn rips 0.7 seconds off the 0-60 mile-per-hour time, getting you there in 4.6 seconds.

Audi follows suit with TDI stop-sale

Yesterday, Porsche issued a stop-sale on its Cayenne Diesel, following the news that the Volkswagen Group's 3.0-liter diesel V6 is also fitted with cheating software. Now, according to Automotive News, Audi is issuing a similar stop-sale in the US, but in the case of that brand, it affects more than just one model. Audi's stop-sale covers diesel-powered versions of the 2013-2015 Q7, as well as the 2014-2016 A6, A7, A8, and Q5. All of these models can be had with the 3.0-liter TDI V6, which up until this week's news, was not included in Volkswagen's massive diesel scandal. No recall is currently planned, according to Automotive News. Additionally, Volkswagen has yet to issue a stop-sale on its Touareg TDI, which also uses the 3.0-liter V6. The Touareg TDI can still be found on Volkswagen's consumer site, as of this writing.
