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.

597-hp Audi RS7 Performance coming to US

The Audi RS6 Avant and RS7 Sportback certainly aren't hurting for power. Their 4.0-liter, twin-turbo V8s offer mountains of muscle as tall as the Alps. However, the engineers at the Four Rings are pushing those peaks just even higher for the new Performance versions of the pair. Tweaks to the engine management, bring horsepower up to 597 ponies and 516 lb-ft of torque. Temporary overboost can take the twist to 553 lb-ft, though. This high-performance duo can haul passengers with aplomb by hitting 62 miles per hour in 3.7 seconds – two tenths quicker than a regular RS. Even more impressive, the 12.1-second run to 124 mph also takes 1.4 seconds less than the standard version. Top speed remains the same 155 mph, but the optional Dynamic Package takes off the limiter to let the RS6 reach 174 mph and the RS7 go 189.5 mph. The eight-speed tiptronic remains from the standard RS versions, and it routes power through the Quattro all-wheel drive system with a 40:60 front-rear split. An optional sport differential at the back can also provide some extra assistance. Both Performance models come standard with an adaptive air suspension, but for those willing to spend a little more a stiffer RS sport suspension plus with Dynamic Ride Control is available, as well. The Performance pair launches in Germany at the beginning of November, but there's reason to get excited in the US, too. Audi spokesperson Mark Dahncke confirms to Autoblog that the RS7 Performance is coming here. More details about it should arrive around the Los Angeles Auto Show, he said.
