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 R8 Spyder is latest big New York Auto Show debut

The New York Auto Show hasn't been boring. Highlights so far are the kick ass Mazda MX-5 Miata RF and the new Lincoln Navigator Concept. And now, Audi has added a healthy dose of supercar to the mix with the new R8 Spyder. The headlining stats are familiar, seeing as how they're plucked directly from the new R8 hardtop. The only powertrain option is the 5.2-liter V10 and seven-speed S-Tronic dual-clutch transmission. That engine, as in the hardtop, is good for 540 horsepower and will get this droptop German to 62 miles per hour in just 3.6 seconds (only a tenth of a second off the Coupe's time). The convertible R8 will run all the way up to 197 miles per hour. Audi's release makes no mention of a higher-performance V10 Plus model, which is available on the R8 Coupe. That top-end trim bumps output to 610 ponies and cuts three-tenths of a second off the base hardtop's 3.5-second run to 60. The upside, of course, is unlimited headroom. The new fabric roof can be opened or closed at speeds up to 31 miles per hour, and the operating time is 20 seconds in both directions. The R8 Spyder hasn't exactly been a secret. We've spotted it testing as recently as August, and it was included on a leaked product road map last month with a listed March/April debut. Check back later for a full round of live images from the R8's New York debut. Until then, check out our first images of the new R8 Spyder, available up top.

Essentially sporty | 2017 Audi A4 Quattro Quick Spin

Two boxes checked on the options list set our long-term Audi A4 2.0T Quattro Prestige apart, dynamically, from the rest. One is the Sport Package, and namely the sport suspension with its lowered ride height. The other is the 19-inch wheel package, which includes 245/35 summer tires. The A4's sport suspension is taut without being rough. The car feels as though it's gliding over the road, but some of the chop makes its way into the cabin. It mostly isn't bothersome, but you can feel – and especially hear – any larger imperfections you happen to hit with one the tires. Our car's 19-inch wheels, with their low sidewalls, amplified the potholes, too. Largely, though, it's comfortable and supremely smooth if the road's not all torn to heck. The sport suspension does an excellent job of eliminating squat and dive, and side-to-side body roll, which aids comfort. That ride makes for really smooth sailing in your daily driving duties, especially since the rest of the car feels so civil. The transmission works smoothly and seamlessly in the background in automatic mode. We do notice some of the gear changes if only because we're tuned into how impressively smooth and quick they are. On its own, the transmission tends to shift low in the rev range so you don't get a lot of engine noise with normal driving. We know that there's some athleticism hiding under this car's preppy facade when we look down at the speedometer and realize we're going quite a bit faster than it feels. It's so well composed, though, that we'd be perfectly okay with putting our grandmother in the passenger seat without feeling like we were going to freak her out if we were to happen to exceed the posted speed limit. But after dropping Grandma off, it's time to put the car into Dynamic mode (tightening up steering and ramping up the throttle behavior) and switch the gear lever from D to S. Using the paddle shifters on the Our personality and that of the car changed, becoming more aggressive. back of the steering wheel, the A4 transforms into a truly engaging driving machine. It shifts very quickly, and the sound of the engine becomes more noticeable in part because you can rev it higher, but also because you're more tuned into it. Upshifts and downshifts happen in an instant, to help make full use of engine's sweet spots.
