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.

More automakers working to turn your smartphone into a shareable digital car key

The smartphone killed the phone book, audio player, the pocket digital camera, handheld GPS devices and voice recorders. Now that addictive, transistor-filled candy bar is coming for your car keys. The Car Connectivity Consortium (CCC) announced that it's unveiled Digital Key Release 1.0 Specification for its member companies, which is the first step in standardizing protocols. As of now, the potential is there for drivers to download a digital key that can lock and unlock the car, start it, and transfer the key to another operator in order to share the car. The CCC's aim is to save development costs, stave off a glut of similar-yet-competing technologies, and create keys that reflect the expanded use cases for cars, i.e., car-sharing services and to-your-car delivery. Next year's Release 2.0 Specification will standardize an authentication protocol between the phone and the vehicle — how a digital key is generated on a secure server and transmitted to the car and the device — and "promise more interoperability between cars and mobile devices." The CCC says that "NFC distance bounding and a direct link to the secure element of the device" will assure security. We take that to mean the phone will need to be in direct contact with the vehicle, at least to open the door. Carmakers and suppliers have been working on digital keys for years now, and the ecosystem for individual owners to open individual cars is growing. Audi showed off its Mobile Key at the 2015 Consumer Electronics Show, and now calls it Audi Connect Key, but we haven't seen much of it in the field. That same year, Volvo said it expected to sell cars with digital keys only by 2017, which clearly didn't happen. Last year, the head of sales at BMW asked, "Honestly, how many people really need [keys]? They never take it out of their pocket, so why do I need to carry it around?" Even though a digital key offers an owner more convenience and long-distance control over their vehicle, car sharing is the target — and that can even include traditional rental cars. In 2013, Continental began testing a digital key in France, aimed at integrating and simplifying the electric-car-sharing business; everything from finding a free vehicle to driving it and charging it could be done on a phone. A key could be programmed with the driver's information, so that any car the driver gets in will be automatically updated with that driver's preferences, say for audio or seating position.

Mueller named Audi boss, too

Matthias Muller, chairman of the board for the Volkswagen Group, has officially taken the role of chairman of the supervisory board for subsidiary Audi. Muller takes over the role from the disgraced Martin Winterkorn. This appointment should come as a shock to no one, and not just because we told you about it last week. Since Audi is part of the Volkswagen Group, which Muller leads, he's effectively been the head of the subsidiary brand since his appointment in late September. This news simply formalizes his positioning at the Ingolstadt-based company. This, of course, is not Muller's first go-around at Audi. He previously served as Head of Product Management Audi (along with Lamborghini and Seat), before taking the lead on product planning at the entire VW Group. Check out the official press release from VAG. MATTHIAS MULLER BECOMES CHAIRMAN OF THE AUDI SUPERVISORY BOARD Ingolstadt/Neckarsulm, December 7, 2015 – The Chairman of the Board of Management of Volkswagen AG, Matthias Muller, has joined the Supervisory Board of AUDI AG and becomes its Chairman with immediate effect. Berthold Huber will continue to be Deputy Chairman. Furthermore, the two vacant seats for members representing the shareholders will be newly occupied by Julia Kuhn Piech and Josef Ahorner. Matthias Muller has been a member of the Board of Management of Volkswagen AG since March 1, 2015 and its Chairman since September 25, 2015. After completing high school in Ingolstadt, he did a toolmaker's apprenticeship at Audi. He then studied informatics at the Munich University of Applied Sciences. After graduating in informatics, Muller continued his career at Audi in 1978, progressing to become the Head of Product Management for the Audi, Lamborghini and SEAT brands. From 2007 onwards, Muller was Head of Product Management for the Volkswagen Group and the VW brand as well as Executive Vice President of the Volkswagen Group. From 2010 until September 2015, Matthias Muller was Chairman of the Board of Management of Dr. Ing. h.c. F. Porsche AG. Josef Ahorner (55) is the chairman of the supervisory board and main shareholder of Emarsys AG, and was a member of the shareholder committee of Salzburger Porsche Holding from 1996 until 2008. Julia Kuhn-Piech (34) is a real estate manager and a member of the supervisory boards of MAN SE and the Truck & Bus division of MAN AG.
