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.

VW internal investigation finds 'no evidence' against suspended engineers

Volkswagen is still working out the chain of events that led to emissions-evading software being installed in 11 million diesel vehicles worldwide and deciding who was responsible for the treachery. So far, the German automotive giant's internal investigation hasn't publicly named many suspects, and three suspended executive-level engineers have been found not to be culpable in the wrongdoing, according to an anonymous insider speaking to Reuters. VW knows that the software began being installed in the EA 189 engine in 2008. The internal investigation has found that the emissions-evading tech was created because the powerplant was found to fail US standards. Plus, the diesel mill wasn't meeting cost targets, according to Reuters. The automaker responded by suspending over 10 employees, but three top engineers among them might not have been involved. Those put on leave include Heinz-Jakob Neusser from VW, Ulrich Hackenberg from Audi, and Wolfgang Hatz who led Porsche's research and group-wide engine development. The internal detective work hasn't turned up any evidence against these three men. In addition to VW's own inquires, government investigators in both the US and Germany are taking a serious look into the company's actions, too. So far, the automaker is setting aside about $7.3 billion to pay to fix the vehicles with the evasive software. Depending on what authorities find, the costs could grow quickly. Beyond the financial implications, the scandal has led to a serious shakeup in VW's corporate structure. Related Video:

Will Audi's e-tron SUV's range match the Tesla Model X?

Tesla may soon get some competition from across the Pond when it comes to battery-electric SUV supremacy. Volkswagen's Audi division is preparing an SUV sized between its Q5 and Q7. And the company is suggesting that the model's single-charge range may challenge that of the Model X. Audi's battery-electric SUV, which was first shown off in a concept version at the Frankfort Auto Show in 2015, may start sales as soon as next year. More importantly, the model could have a single-charge range of more than 300 miles, UK's Autocar says, citing an interview with Audi executive Dietmar Voggenreiter. Granted, that estimate is likely for Europe's more generous NEDC cycle, which would put the range at closer to 250 miles by US Environmental Protection Agency (EPA) standards. Still, 250 miles would beat the 200-mile range of the base-model Tesla Model X and would be in spitting distance of the 100D model's 295 miles. What that means for US customers - price, on-sale date, and range - is unclear. Audi spokesperson Amelia Fine-Morrison, in an e-mail to Autoblog, said it was "too soon to confirm the details," and that the automaker would disclose more information closer to the official launch date. Still, Audi has said it looks to have as much of 25 percent of its global offerings be electrified by 2025, so this will likely be a big step towards that goal. Then there's the question of how big the domestic market will be (not to mention how much the Audi SUV EV will cost). During the three months ended Dec. 31, 2016, Tesla delivered a quarterly-record 9,500 Model X vehicles, so there will obviously be high-end demand for an electric SUV from an established brand like Audi.
