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 TT Second Drive [w/video]

The original Audi TT is a modern style icon. But having a one-time design hit isn't a recipe for longevity. In order to succeed, you have to bolster style with substance. Thankfully, that's exactly what Audi did with its third-generation TT. Now more than ever, the TT is a proper sports car, and it debuts with a host of new technology. The car still looks good, but it's no longer a one-off masterpiece. Instead, it takes many of the original TT's elements and incorporates new bits of modern detailing. The shape is all TT – the roofline, the wheel arches – even smaller details like the fuel filler cap and exhaust outlets moved closer to the center of the vehicle pay homage to the original car's design. But the new car's face is more angular, more robotic. Park the new R8 next to this TT and the family resemblance is clear. "It's fair to say that the new car hasn't been comprehensively reconceived; it's been comprehensively re-detailed," says associate editor Jonathon Ramsey, who first drove a Euro-spec TT back in September. It's a good move, a way to "keep the icon alive," according to Audi AG exterior designer Dany Garand. But the better news is that the rest of the car is more than just a comprehensively re-detailed machine. Launch a TT coupe from a stop and you'll hit 60 miles per hour in 5.3 seconds. The TT rides on the same modular MQB architecture as the Volkswagen Golf. The whole package is the same length as before, but the wheelbase is stretched by 1.5 inches. At 3,186 pounds, the TT is only 11 pounds heavier than its predecessor, but thanks to new body components, it's 25-percent stiffer than the second generation. We sampled the base TT on the roads of northwest Oregon – that means there's a 2.0-liter turbocharged inline-four good for 220 horsepower and 258 pound-feet of torque. It's the same output as a GTI with the Performance Package in a two-door coupe that's 155 pounds heavier. But stay with us – the magic of Quattro all-wheel drive seriously comes into play here. Launch a TT coupe from a stop and you'll hit 60 miles per hour in 5.3 seconds. Even the TT Roadster is a firecracker, able to do that same 0-60 run in 5.6 seconds. That 220-hp, front-wheel-drive GTI, by comparison, hits 60 in about six seconds flat. We didn't get to drive the TTS, but based on numbers alone, it ought to be a real honey. The S uses the more powerful version of the 2.0T engine from the Golf R, with 292 hp and 280 lb-ft of torque. Zero-60: 4.6 seconds.
