300-HP 2013 Audi S3 Sportback unwrapped

Not content to let Volkswagen have all of the fun with its GTI and Golf R, Audi is rebooting its five-door S3 Sportback with rather monstrous power. Headed for an official unveil at this year's Geneva Motor Show, the new S3 rolls out with a 300-horsepower, 280-pound-feet of torque turbocharged 2.0-liter TFSI engine under the hood. The four-cylinder powerplant is strong enough to shove the Sportback to 62 miles per hour in just 5.0 seconds when connected to the optional S-Tronic gearbox, or 5.5 seconds with the traditional manual transmission. Top speed is said to be an electronically governed 155 mph. Almost as impressive as those performance figures are the fuel economy ratings: the S- S3 is said to average 34 miles per gallon.
All S3 Sportback models offer Quattro all-wheel drive, ride on a sport-tuned suspension tuned to a lower ride height (about one inch) versus the standard Audi A3. 18-inch wheels with 225-section tires are standard equipment, and 13.39-inch front brakes should offer serious stopping ability.
Audi has done a lot of work shedding pounds from this latest MQB-architecture S3, as well. The car has a curb weight of roughly 3,186 pounds, or some 154 pounds less than the outgoing model. 11 of those pounds were cut via weight-saving measures in the 2.0-liter engine.

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.
