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.

2017 Audi Q7 First Drive

Automotive evolution rarely makes a great leap, instead creeping along from new model to new model at a predictable pace. Audi's new Q7, though, is like handing a Bic lighter to a Cro-Mangon man smashing rocks. In Europe the new version drops 700 pounds, almost enough to reclassify its species. Audi's fire-machine will arrive in America in early 2016, as a 2017 lighter model. We spent some time in the Swiss Alps flicking the 2017 Audi Q7. As far as revolutions go, the 2017 Q7 certainly looks new. It resembles a tall station wagon more than ever, at least in European trim. A little tweaking of the design wand has left the rear end boxy and angular. Our test models use an adaptive air suspension, and the the "all-road" setting lifts the Q7 about an inch, to the normal ride height for US models. Thus raised, the big Q looks more like an SUV. This Q7 represents the first of the Volkswagen Group's MLB-platform cars. Lighter and said to be more dynamic, MLB will underpin everything from the next-gen A4 to performance and luxury SUVs like the Porsche Cayenne, and Bentley Bentayga. With the structural improvements comes a diet heavy in aluminum, the prime reason for the previously-mentioned weight savings. When outfitted for our content and crash-safety specification, US-bound models will still be about 500 pounds lighter than before. But dramatic weight-savings isn't the Q7's only trick. The adaptive air suspension significantly changes the character of the Q7, especially in the sportiest Dynamic model. There's an optional all-wheel steering feature that improves turning radius, and helps with high-speed stability. This is not to be confused with Audi's Quattro all-wheel drive, which along with a panoramic sunroof and seven seats, comes standard on all stateside models. Under the hood, things aren't so different. Both available engines are reworked but largely the same. The supercharged 3.0-liter gas engine still makes 333 horsepower and 325 pound-feet of torque, but it's not as thirsty as it used to be. Expect a two or three mile-per-gallon bump once official EPA ratings arrive. That engine, as well as Audi's reworked 3.0-liter V6 TDI – good for 260 hp and 443 lb-ft once outfitted for the US – are mated to the ubiquitous ZF eight-speed transmission. The Q7's driving character greatly depends on where it is pulling power from. While the diesel model is capable, turbo lag cuts back on the satisfaction we normally derive from oil burners.

2016 Audi R8 E-Tron packs 456 hp and goes on sale this year

For the longest time, the Audi R8 E-Tron seemed like such a fantasy, we never really though it'd come to fruition. But it's here, in second-generation R8 form. It's really, actually, finally here. It looks like a electrified R8, too, with oversized, EV-spec wheels, and a revised front fascia that lends itself well to the more chiseled design of Audi's mid-engine coupe. Thanks to that nice shape and those air-slicing wheels, Audi has achieved a drag coefficient of 0.28 for the R8 E-Tron. The 92-kWh, T-shaped battery is actually integrated into the center tunnel behind the passenger compartment, so it helps with the car's weight distribution and center of gravity. The two electric motors are mounted at the rear. As for the specs, things look awesome: 456 horsepower, 679 pound-feet of torque, 0-62 in 3.9 seconds, top speed of either 130 or 155 miles per hour, a range of 280 miles and a charging time of less than two hours. And it's going on sale. Like, for real. Audi's press blast clearly states, "Upon customer request, the R8 E-Tron will be available for order in 2015 as an electrically powered sports car in supreme hand-built quality." Consider us stoked. Electrified: Audi R8 e-tron The second generation of the Audi R8 forms the basis for two more models. Audi has made major engineering developments in its high-performance electric sports car, the R8 e-tron. The latest evolution of the vehicle takes up the multimaterial Audi Space Frame from the new series-production model. The supporting structure was enhanced by a CFRP rear-section module comprising the luggage compartment. The walls of the CFRP luggage compartment well are corrugated. This way, in the event of a rear-end collision, more energy can be absorbed despite the reduced material weight. Thanks to targeted modifications to the outer shell and on the wheels, the Audi R8 e-tron achieves an aerodynamic drag coefficient (cd) value of 0.28. In terms of performance and range, the car enters entirely new dimensions. The large T-shaped battery is structurally integrated into the center tunnel and behind the occupant cell – optimally positioned in the car. It supports the dynamics of the R8 e-tron with its low center of gravity. Audi produces the high-voltage battery itself, for the first time based on a newly developed lithium-ion technology which was specially conceived for a purely electric vehicle drive.
