2017 Audi A4 First Drive [w/video]

Internally, Audi refers to the A4 lineage with a B designation. Why the discrepancy? The model legacy traces back to the 1972 Audi 80, and the A4 name wasn't adopted until 1996 for the North American market. So the fifth-generation A4 is code-named B9. There is no confusion about what this car means to Audi. In 19 years, the brand has sold more than 12 million A4s around the world, which puts this new generation on the A-list when it comes to brand importance. If you squint, the new car looks like a facelifted version of the last-generation facelift unveiled in 2013. We get the same impression of the new A4 as we do with the third-generation Audi TT: it hasn't been comprehensively reconceived, it's been comprehensively re-detailed. But with a move to the updated VW group platform known as MLB Evo, 90 percent of the components on this car are new. On the outside, those changes are reflected through deeper sculpting on a body that's about the same height as before but 0.5-inches wider, one-inch longer, and with a wheelbase stretched 0.7 inches. The tweaked grille separates reworked Bi-Xenon headlights, which are standard across the lineup now – halogens go bye-bye. LED headlights are optional, as are the matrix units in other markets. Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. Above those lights is a version of a clamshell hood – its shutline forms the front third of the pronounced shoulder line along the sedan's flanks. Audi designed a new hinge that keeps the hood lined up properly over the life of a car because small misalignments show more easily on the vertical seams. In back there are updated taillights, a standard rearview camera, and a trunk opening that's an even one meter across. In the press presentations, any conversation quickly turns to weight loss and aerodynamic efficiency. The only curb weight we have from Audi so far is for the base sedan, empty and without a driver, with the 1.4 TFSI engine that we don't get, coming in at 2,910 pounds. The current US-spec A4 is listed at 3,583 pounds, and Audi claims US-market cars will lose anywhere from 70 to 100 pounds depending on specification. About 35 pounds of that comes from the chassis, with new forged aluminum links on the suspension, fixed-caliper, four-piston brakes up front, and wheels that are never heavier than 26 pounds. The rest of the weight loss comes from the body, mostly through greater use of aluminum.

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 A3 Clubsport Quattro concept bringing its 525 horses to W?rthersee

It's almost late May, and you know what that means: the last of the snow has melted, the Stanley Cup playoffs are in full swing, the flowers are blooming, and the performance-car faithful are descending on Wörthersee in Austria for the annual GTI-Treffen.
Not only is the Wörthersee Tour (as the automaker calls it) a chance for enthusiasts to show off their rides, it's also a prime opportunity for the Volkswagen Group to show some of its most dedicated customers what it can do. Past meets have given us such notables as the Audi A1 Clubsport Quattro, Volkswagen GTI W12-650 and Skoda Fabia RS 2000 Roadster, to name just a few. And now Audi has emerged as the first VW Group brand to reveal what it has in store.
It's called the A3 Clubsport Quattro, and seems to offer a pretty clear indication of what we should expect of the next RS3. The concept is based on the S3 sedan, but swaps out its 2.0-liter turbo four for a retuned version of Audi's sweet 2.5-liter turbocharged inline-five, retuned to produce a massive 525 horsepower and 442 pound-feet of torque.
