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.

Audi reveals new TT spec racer

We've seen the coupe. We've seen the convertible. We're still waiting on word of the next variant, but before it arrives, Audi has revealed the racing version of the new TT.
Set to form the backbone of the inaugural Audi Sport TT Cup, the competition-spec sports coupe is closely based on the production version packs the same 2.0-liter turbo four and six-speed dual-clutch transmission as the road-going TTS, delivering the same 310 horsepower, but with a push-to-pass boost of an extra 30 hp.
It's also got an active differential, and while the full specifications have not yet been revealed, it's clear that Audi has also outfitted the TT racer with more aggressive aero, track-spec rolling stock and a stripped-out cockpit (complete with the Audi PS1 Safety Seat from the R8 LMS Ultra) to get weight down to from 2,700 pounds in stock production form to 2,480.

2018 Kia Stinger vs. other luxury hatchbacks compared by the numbers

Ten years ago, if you had told us that one of the many new luxury segments to develop would be sedan-style hatchbacks, we'd have said you'd lost your mind. And yet, here we are today with not one, but four cars competing in just such a niche upscale segment: The Kia Stinger, Buick Regal Sportback, BMW 3 Series Gran Turismo and Audi A5. That's just in one size and price bracket. Two of the manufacturers listed here make larger versions of each luxury hatchback. We aren't entirely sure how it happened, but we're not going to complain, because we love the idea of a car with almost no compromise: luxury features, sporty performance, and plenty of practicality. Try Autoblog' s Car Finder to search for your next new vehicle. One of the reasons we're taking a look at these cars right now is that Kia has recently released pricing for its entry in the segment, the Stinger and Stinger GT. Buick wasn't far behind with the Regal Sportback and Regal GS, nor was Audi with the A5 and S5. So it seemed like an appropriate moment to look at the numbers and see which come out ahead or behind, with victors in each category highlighted with bold and underlined text. What we found when comparing these cars' statistics is that each one has a clear area of expertise. For performance, it's hard to beat the four-cylinder Kia Stinger and the V6 Stinger GT. The four-banger has the most horsepower of the four cars, and is just behind on torque. The V6 has the most power and torque among the six-cylinder versions. The Stingers are also the second lightest of the group when equipped with rear-wheel drive, though they fall to third with all-wheel drive. Space is a split between the Buick Regals and BMW 3 Series Gran Turismos. The Buicks have the most cargo space with the rear seats up or folded by a significant margin. The BMW on the other hand generally offers more space for passengers. It's up to you what's most important. Compare these and other potential new vehicle purchases using our tool. When it comes to cost, nothing can beat the four-cylinder Regal's base price of under $26,000. But if a V6 is what you're after, the Stinger GT is the cheapest. Neither matches the Audi A5 and S5 for fuel economy, though. Both Audis have the highest numbers for city, highway, and combined EPA estimates. Related Video:
