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.

Audi A3 diesel fails independent emissions test in Europe

The best-selling model under Volkswagen's Audi division was emitted about double the legal limits of nitrogen oxide (NOx) levels for Europe, Reuters says, citing laboratory tests overseen by the European Commission's Joint Research Center (JRC) in August. The Audi A3 was found in two tests to emit about double the legal limit of NOx, though one of the tests had the A3 within the limits when the engine was cold. An Audi spokesman told Reuters that the A3 was independently tested to have emissions levels within the legal limit and that he wasn't aware of the JRC test results. Still, the findings are another example of how Volkswagen, Europe's largest automaker, can not seem to shed the issues surrounding the diesel-emissions scandal that broke last September. VW has been fined about $19 billion for equipping diesel cars with software that cheats emissions-testing systems. About 11 million cars were affected, including about a half-million vehicles in the US. In addition reaching a $15 billion settlement with US regulatory bodies such as the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) earlier this year, VW has been fined $15 million by the South Korean government, which may impose more penalties because of allegations of false advertising. Audi is not the only VW unit to face further scrutiny. Germany's Transport Ministry and Federal Motor Transport Authority are taking a closer look at VW's Porsche division for potential emissions-cheating efforts, Bloomberg News recently reported. Additionally, the European Union is saying that at least seven of its member nations failed to provide sufficient oversight of automobiles' emissions-testing process, and may take legal action against Germany, Spain, Luxembourg, Czech Republic, Lithuania, Greece, and Great Britain, according to a separate Reuters article.

Audi Adaptive Cruise Control | 2017 Autoblog Technology of the Year Finalist

Not your father's cruise control, Audi's adaptive system is another step on the road to autonomous driving. That earns it a spot as one of our Technology of the Year finalists. Audi Adaptive Cruise Control can slow down or speed up your vehicle depending on the conditions. It's also capable of coming to a full stop and then resuming speed. This allows the vehicle to move with traffic without engagement from the driver using Traffic Jam Assist at speeds up to 40 miles per hour. It's not being marketed as an auto-pilot setup. Rather, this system can increase driver safety by automatically braking as the vehicle in front slows and then accelerating once the path becomes clear. The cruise control has five programmable settings to regulate distance between vehicles. Linked with the navigation system, Audi's ACC suite uses a camera and radar to respond to its environment, a key development for future systems that will need to communicate with the grid. The system can read street signs, allowing it to slow down or speed up. Additionally, when a destination is set, the vehicle will automatically brake when a turn is looming to alert the driver he or she needs to take action. It will brake through the turn and then speed up upon completing the maneuver. We especially liked this, as many navigation systems don't inform the driver when to turn or take an exit until the last possible moment. Further, when navigating curves, the Audi system will brake the vehicle and resume speed as conditions require. This Adaptive Cruise Control is a layer of artificial intelligence we can get on board with. It's like having a co-pilot to assist the driver when the inevitable fatigue or distractions appear. It engages like a normal cruise control system. Simply pull the stalk in the steering wheel mount, and there's a button to modulate the distance. We tested Audi's Adaptive Cruise Control on an A4, where it is an $1,800-option as part of the Driver Assistance Package. Working in combination with Audi's Virtual Cockpit and head-up display, ACC provides the driver a sense of awareness and greater level of information than other systems on the road. Companies like Volvo and Porsche offer similar setups, but we like the intuitiveness of the Audi program. Automakers have been saying for years that the autonomous technology is essentially here, they just need the infrastructure and regulations to catch up.
