Audi unveils A3 Sportback G-Tron with bi-fuel power, 808-mile range

By this time next year, the Audi A3 Sportback will be offered with a variety fuel-efficient powertrains ranging from diesel to the all-electric E-Tron, but perhaps the most interesting is the all-new G-Tron model, which uses Audi's innovative carbon-natural compressed natural gas called e-gas. Previously called A3 TCNG, we first heard about this technology last year, but now Audi has confirmed that this low-emission, sustainable-fuel will debut by the end of this year on the A3 Sportback G-Tron.
To create this e-gas, a plant in Werlte, Germany uses electricity to split water into hydrogen and oxygen. As hydrogen fuel cell vehicles become more popular, Audi says that this process could also be used to produce hydrogen fuel, but to create CNG, it mixes the hydrogen with carbon dioxide to create "synthetic methane." Since it is identical to the CNG available today, Audi's e-gas can be shipped and stored using the existing CNG infrastructure. Making the whole process even greener, Audi obtains the CO2 for this process from a nearby biogas plant, which would otherwise be released into the atmosphere.
Differentiated from the regular versions of the A3, the G-Tron features a pair of tanks under the rear cargo floor holding 15.43 pounds of CNG, which can power the car for almost 250 miles. What's more, the A3's conventional gasoline tank is still in place, giving the car an addition 560 miles of range. In total, that means the A3 G-Tron has a driving range of more than 800 miles. To run on both CNG and gas, Audi made changes to the car's 1.4-liter four-cylinder engine (including the turbo, cylinder head and fuel injection system) and catalytic converter.

Next Audi R8 E-Tron could have 280-mile range

Just 265 miles of range on a single charge? Meh. That's what the folks at Audi might be saying about the Tesla Model S and its estimated range. Because the German automaker says the next iteration of the R8 E-Tron could go 450 kilometers on a charge, or about 281 miles. This information comes from Automotive News, which cites a presentation from Audi technology chief Ulrich Hackenberg at the company's annual press conference. The fact that the car will soon be available "upon request" is also news. The project was thought to be shelved until reports came out late last year saying that Audi figured out a way to upgrade its lithium-ion battery technology to double its range. Audi spokesman Brad Stertz said the company wasn't disclosing details related to if or when the car would reach North America or how much it would cost (we're guessing a really large number of dollars) but he did say it was notable that the project was back on track. Audi made news in the summer of 2012 when the R8 E-Tron set the "series production electric car" speed record with a 8:09.099 minute-time at Nurburgring thanks to a boosted top speed of more than 155 miles per hour.

Audi S1 officially shows itself as 228-hp hot hatch [w/video]

We got the first leaked pics of the new Audi S1 Sportback five-door hot hatch yesterday, and as expected, Audi has unloaded the full details today, including confirmation of its S1 three-door sibling ahead of its debut at next month's Geneva Motor Show. The two cars are essentially identical aside from their door counts, and together, they represent a new entry-level rung into Audi's S car range.
The subcompact S1 is propelled by Audi's ubiquitous 2.0 TFSI four-cylinder, tuned here to produce 228 horsepower and 279 pound-feet with a six-speed manual transmission and all-wheel drive. The potent combo accelerates the S1 to 62 miles per hour in 5.8 seconds (5.9 seconds for the Sportback) and on to a top speed of 155 mph. Fuel economy is rated at an average 33.6 miles per gallon (40.3 mpg UK) in the UK cycle. The S also gets a completely different four-link independent suspension to replace the less sophisticated torsion beam setup found in the standard A1.
Styling also gets a bump in aggressiveness that befit the S1's performance upgrades. In addition to a new body kit with a lower front air dam and 17-inch wheels, the S1 comes standard with Xenon headlights, LED taillights and two new available exterior colors ­- Vegas Yellow and Sepang Blue. The interior gets combination leather and cloth sport seats, piano black trim and a retractable 6.5-inch color infotainment display.
