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.

2015 Audi A8 rises to meet the challenge [w/video]

It's turnover time in the extra large premium sedan segment. With Mercedes having stuffed HAL 9000 in its new S-Class, other luxury marques are quickly updating their own super sleds to keep up with this persistent march of technology. While far from a full redesign, the Audi A8 has changed enough for 2015 in terms of styling, powertrains and new technology to keep it in the conversation.
For starters, the A8's exterior design has been redone, with the most noticeable changes happening up front. The trademark 'gaping maw' grille is a little less gaping, while the headlights now feature a straight lower edge of LEDs, excising the old model's droopy-eyed look. Speaking of headlights, Audi now offers optional Matrix LEDs, the latest in headlight tech, with 25 individual elements per side that can be turned on or off and dimmed as the situation demands. The rear of the A8 has also been resculpted and looks very much inspired by the derrière of the A7, with a single chrome strip connecting the new LED taillights.
The A8's full suite of powertrains has also been upgraded, with the supercharged 3.0-liter V6 now producing 310 horsepower (up 20 according to Audi, though down 23 compared to the US-spec 2013 model). The twin-turbo 4.0-liter V8 is now rated at 435 hp, a solid 20-horse increase that lowers the car's 0-62 time to just 4.5 seconds. That's within spitting distance of the 520-hp S8's time of 4.1 seconds. That aforementioned super sport sedan's engine remains unchanged, as does the 6.3-liter 12-cylinder powerplant in the A8 L W12, but Audi's two diesel engines have both improved, with the 3.0-liter V6 producing an extra eight horsepower (256 total) and the 4.2-liter V8 gaining an extra 34 hp (385 hp) to go along with its more-than-adequate, though unchanged, 626.93 foot-pounds of torque.

Audi bringing TT Clubsport Turbo concept to Worthersee

Is the world ready for an Audi TT with 600 horsepower? Well it had better be, because that's exactly what Ingolstadt has in store for this year's GTI-Treffen at Worthersee, Austria. Billed as a "technology concept," this TT show car packs a 2.5-liter inline-five with two electric turbochargers. Audi is developing electric turbos for its diesel engines, but has found a performance application here in a gasoline engine. The result is a whopping 600 horsepower and 479 pound-feet of torque, driving all four wheels through a six-speed manual transmission. Weighing in at 3,078 pounds and with those electric turbos spooling up quick, it's said to reach 62 in 3.6 seconds en route to a top speed of over 192 miles per hour. In a TT. The turbos are powered by a 48-volt electrical system, juiced by a compact lithium-ion battery in the trunk that can store regenerated power. It's also got a coilover suspension and electric jack to get over obstacles like curbs and speed bumps. The whole thing rides on 20-inch alloys with a two-tone finish, with carbon-ceramic discs to keep it all in check, and as you can see, a rather aggressive-looking widebody aero kit. All of which makes for a rather stunning concept, even if its encroachment on the R8 means it will likely never see production.

From May 13 to 16, Audi will be showing its technology concept car on the Worthersee Tour in the Austrian town of Reifnitz. The inspiration for the show car came from the successful Audi 90 IMSA GTO of the late 1980s. A new technology is making its debut under the hood. The car's electric biturbo adds even more dynamism to the driving experience with its spontaneous response. "The electric biturbo signifies a new dimension in driving enjoyment; it boosts sprinting ability and torque and enables high peak power," explains Prof. Dr. Ulrich Hackenberg, Audi Board Member for Technical Development. "In our TDI engines, we are close to production readiness with this technology.
