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.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.

IIHS bestows 2015 Audi A3 with Top Safety Pick+ [w/video]

There's some good news for Audi today, as the Insurance Institute for Highway Safety has named the all-new A3 one of its Top Safety Pick+, the institute's highest award for safety.
While there are no shortage of cars that can handle the standard IIHS trial, the tough small overlap test needed to earn TSP+ has flummoxed more than a few vehicles from prestigious, safety minded manufacturers. In the A3's case, though, it handled the small-overlap tests well.
According to the IIHS, there wasn't much intrusion into the cabin from the impact, which simulates a 40-mile-per-hour impact on 25 percent of a car's front end. The crash test dummy was held in place, with just a low risk of injuries. You can view the crash test video below, as well as read a brief press release from the IIHS.
