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 builds 5-millionth vehicle with Quattro

Quattro, the trademark name Audi has put on its all-wheel-drive system engineered for passenger vehicles, recently celebrated its five-millionth installation. The driveline has been offered in more than 140 different vehicles since its introduction more than three decades ago.
The all-wheel-drive technology made its world debut at the 1980 International Geneva Motor Show, beneath the floorpan of the Quattro Coupé, a low-volume two-door. It didn't take consumers long to embrace Audi's innovative approach. While most four-wheel-drive systems at that time utilized heavy transfer cases or second cardan shafts, Quattro was virtually tension-free, light, compact and efficient. Most importantly, enthusiasts found it was especially suitable for sports cars.
Today, the automaker offers Quattro on its full line of passenger vehicles and it is unquestionably successful (the technology enjoyed a 43 percent take rate in 2012). On models with transverse-mounted engines (A3 and TT), Audi uses an electronically controlled multi-plate clutch with hydraulic actuator. Under normal conditions, the clutch sends power almost exclusively to the front wheels (if wheel slippage occurs, up to 100 percent of the torque may be sent to the rear). Vehicles with transverse-mounted engines (A4, A5, Q5, etc...) use a self-locking center differential sending 40 percent of the engine torque to the front axle and 60 percent to the rear under normal conditions (it is able to send the majority of the power to the axle with better traction when needed). The highest-performing Quattro systems use torque vectoring to further improve cornering grip and speeds.

2014 Audi SQ5

It may be obvious at this point, but here in the United States, European manufacturer routinely give us the short end of the stick. Now, I'm not talking about models or brands that don't come here, like the Mercedes-Benz A-Class or the entire Renault line. No, instead, I'm referring to cars that are sold right here in the Land of the Free in one bodystyle, while Europe enjoys the same vehicle with a wider variety of configurations.
A prime example of this is the Audi S4/S5 line. In America, we can have the supercharged twins in two-door coupe, four-door sedan, and cabriolet body styles. Meanwhile, our Euroland cousins get the same trio of bodystyles, as well as the A5/S5 Sportback, a characterful 'four-door coupe,' and a versatile hauler, the S4 Avant. At first glance, Audi of America lacks a vehicle that can compete with the latter's blend of performance, versatility and subdued looks. So, what's an American with around $60,000 and an obsession with quick, conservative haulers to do? Well, he can buy an SQ5. (Though it bears mentioning, our US-spec SQ5 is vastly different than what's available to our European friends.)
The SQ5 has a huge number of things going for it that make it a viable alternative to a proper hot wagon, and foremost among them are its looks - this is a sleeper. Audi has thankfully decided not to molest the clean looks of the standard Q5 when penning the sportier model.
