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.

Volkswagen Group's Vision 2030 strategy could bring revolution to the brands

One would expect a corporate plan called "Vision 2030," looking 11 years ahead through wildly tumultuous times, to involve great change and numerous forks in numerous roads. According to Automobile's breakdown of Volkswagen's path forward, though, the plans contain some lurid potential surprises. The ultimate aim is return on investment, and that means ruthless reorganization of a conglomerate with eight primary car brands, two car sub-brands, and Ducati motorcycles. The first two Vision 2030 cornerstones Automobile mentions are near boilerplate: Production network restructuring, and "streamlining of key technologies." The latter two are the ones that could upend what we know as the Volkswagen Group: focusing on the Group's core brands — meaning Audi, Porsche, and VW — and transitioning to EVs, autonomy, and other mobility solutions. Based on the report, a quote from Audi's CTO referring to the Audi brand could cover how the Group plans to handle all of its brands: "We need to find a sustainable solution for the indefinite transition period until EVs eventually take over." The boutique divisions adjacent to carmaking, Ducati and Italdesign, look likely to be spun off. For the halo car brands — Bentley, Bugatti, and Lamborghini — apparently shareholders want double-digit returns on investment, and the trio doesn't have long to hit the target. One eyebrow raiser is when the report states, "Bugatti is tipped to be gifted to [ex-VW Group Chairman] Ferdinand Piech." Piech fathered the Veyron during his tenure at VW, and it was thought he commissioned the La Voiture Noire, but he's lately stepped so far back from VW that he sold all his shares in the Group. Automobile quoted a senior strategist as saying of money-losing Bentley, "Why invest on a backward-looking enterprise when you can support a trendsetter? A proud history and excellent craftmanship alone don't cut it anymore." We guess no one at Ferrari, McLaren, or even Porsche got that memo. Bentley is reportedly close to being put in time out, and if brand CEO Adrian Hallmark can't right the Crewe ship, the hush-hush Plan B is to prop the Flying B up enough to lure a buyer. As for Lamborghini, caught between two masters at Audi and Porsche, even record-breaking numbers at the Italian supercar maker barely staved off sacrilege. It's said that VW brand CEO Herbert Diess considered putting a 5.0-liter Porsche V8 into the Aventador successor.

Notes from Day One of the 2013 Twelve Hours of Sebring

The 61st edition of The 12 Hours of Sebring is on, and Autoblog has come to central Florida with Audi to feast on jumbo boiled peanuts, pickled eggs and the final race for the LMP1 class at the oldest road course in North America. As Audi has been doing for more than a decade now, it's brought its latest endurance race car, the 2013-spec R18 etron quattro, to Sebring to begin testing for Le Mans.
Why the commitment to Sebring? Audi Sport executives have repeatedly called Sebring "punishing," "extremely demanding" and "one of the toughest tracks in the world." It is a 3.47-mile circuit that, in places, feels like it was made from the leftover bits of other circuits. Doing the 12-hour distance in Florida is thought to be a good start on lasting the 24-hour distance in France, and we can't think it a coincidence that Audi has won ten times here in the last 13 years and 11 times in Gaul.
Where there's rhyme - and victory - there is reason. We think we found a few of them on our first day where preparation, technology, fastidious attention to detail and sweat fit right in with swamp cabbage...
