Audi celebrates original RS with RS4 Avant Nogaro selection

It's been 20 years since Audi unveiled the RS2 Avant, the progenitor of an entire range of ridiculously fun luxury cars, including the RS3, three generations of the RS4, three generations of RS6, the RS5, and new RS7 and RS Q3. In honor of the anniversary, Audi is paying tribute to the Porsche-fettled wagon by releasing a special edition of its modern-day counterpart, the RS4 Avant.
Called the RS4 Nogaro selection, it sports vibrant Nogaro Blue paint, which is similar to the RS2's signature color. The twin oval exhaust, window frames, and grille surround are finished in gloss black, while the roof rails are matte black. 20-inch wheels in a V-spoke pattern are the RS4 Nogaro's final exterior tell.
In the cabin, Nogaro Blue Alcantara suede accents are optional on the door panels and seat inners (black suede is also available), while Valcona leather comes standard on the seat outers. The steering wheel, meanwhile, features Nogaro Blue contrast stitching and is wrapped in black leather. Blue threads in the carbon fiber trim and a special-edition shifter round out the interior work on this special edition RS4.

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 R8 Competition ready to rock LA

The heyday of the first-generation Audi R8 is winding down, and the Four Rings already has a bespoke factory to start building the next model soon. In the meantime, the German brand is sending its supercar off with a bang at the 2014 Los Angeles Auto Show in the form of this limited-edition 2015 R8 Competition - the most powerful production vehicle ever made by the company.
Audi is earmarking just 60 examples of the Competition for the US, and this is more than just a trim package to say farewell. Power for the supercar comes from the usual 5.2-liter V10 that's massaged to develop 570 horsepower, an extra 20 hp over the already quite potent V10 Plus, and the only available transmission is the seven-speed, dual clutch S Tronic gearbox. The tweaks let this limited R8 rocket to 60 miles per hour in 3.2 seconds and achieve a maximum velocity of 199 mph. To haul that speed to a stop, it also gets ceramic brake disks with red calipers.
Of course, having such a rare supercar means showing off a little. Audi takes inspiration from the R8 LMS Ultra racecar for the Competition and tries to bring some of its details to the street. The model wears matte carbon fiber pieces replacing the rear spoiler, mirror housings, side blades, front spoiler and rear diffuser. For an extra mean-looking touch, it also has high-gloss black paint covering the wheels and exhaust pipes.
