Updated Audi R8 GT caught testing

When Audi introduced the refreshed 2014 R8, one of the first things we noticed was that the new R8 V10 Plus offers identical output to the outgoing R8 GT, suggesting that this limited-production model was either due to be cancelled or poised for a serious power increase. Fortunately, these spy shots have us suspecting that the latter is more likely.
Like the previous R8 GT, this new model will likely hit the gym, dropping some weight and packing more punch, but while that's all speculative, we do see that better handling is definitely in the cards. Aside from the aero-improving chin spoiler, fascia winglets and fixed rear wing, this R8 also has upgraded brakes with bigger calipers and what appear to be cross-drilled ceramic rotors. We hear output could be increased from the current 560 horsepower up closer to the 600-hp range, and laid to the pavement via Audi's Quattro all-wheel-drive system. It also very likely that Audi will keep production numbers for a 2014 R8 GT rather low, with the outgoing model limited to just 333 units globally.

Audi and FAW to launch A6 E-Tron in China

Audi and its Chinese joint-venture partner FAW have announced that they'll be building a production version of the Audi A6 E-Tron Concept, shown at the 2012 Beijing Motor Show. Based on the China-only long-wheelbase A6, the plug-in-hybrid model is being targeted specifically at the People's Republic.
Audi is promising a 50-kilometer (31-mile) electric range for the fuel-sipping sedan, although there are precious few details beyond that. We do know, though, that this will be a Chinese-built vehicle, with assembly slated for the FAW-Volkswagen joint-venture factory in Changchun. We presume we'll find out more when the Beijing Motor Show kicks off a few weeks from today.
"We are the market leader in China's premium segment and will continue systematically with the application of efficiency technologies. Audi is thus supporting the Chinese government's targets for the reduction of fuel consumption," said Dr. Dietmar Voggenreiter, the president of Audi China.

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.
