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.

Hackenberg says next Audi A4 set for Frankfurt debut

The current Audi A4 is among the oldest vehicles in the brand's lineup. Having debuted back in 2008, it's long overdue for an update, and according to our friends at Indian Autos Blog, that'll happen in roughly six months. IAB spoke to Audi research and design chief Ulrich Hackenberg, who indicated that the fifth-generation A4 will be shown at the 2015 Frankfurt Motor Show in September. The new sedan will be unveiled in "a pre-presentation" before the auto show itself, Hackenberg told IAB, adding that "you'll be happy to see it." Information beyond that, though, remains sparse. Based on our previous spy photos, we expect the new A4 to ride on the Volkswagen Group's modular MLB Evo platform that's been stretched to accommodate a larger wheelbase. The styling, meanwhile, will be more evolutionary, inspired in part by the new TT. Expect more on the next-generation A4 as September approaches. Related Video:

Audi reveals facelifted A7 and S7 in Europe [w/videos]

Audi has revealed the nip/tuck and stylistic upgrades for the A7 that we got clues to in spy shots from back in January. The single-frame grille has been subtly reworked along with the lower front fascia and headlilghts. Those bulbs are underlined by a new design for the LED DRLs, and - in Europe - they can be had with Matrix Beam LEDs that come with dynamic turn signals. Out back is a tweaked bumper, as well as new exhaust tips and taillights with an LED pattern that mimics the front lights.
Cockpit inhabitants get new surface treatments like the aluminum and Beaufort walnut inlays, Valcona leather and five possible colors for the seats. The company's MMI Navigation Plus with MMI Touch is fitted with an Nvidia chip for faster graphics processing, and LTE-enabled internet connectivity is standard.
Up front, the 3.0-liter bi-turbo TDI gets a power boost to 320 horsepower and is attached to an eight-speed transmission; a seven-speed S tronic transmission is paired to the rest of the line. The revised 3.0-liter V6 TDI recently discussed at the Vienna Motor Symposium also joins the lineup, here offered in both the 272-hp and 218-hp variants, that latter "ultra" version said to return 50 US miles per gallon.
