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.

2014 Audi RS7 [w/video]

Stunning Sportback Gets The Performance To Match
Saying the 2014 Audi RS7 Sportback is not as good as the not-for-North-America Audi RS6 Avant we recently tested is a bit like saying one more strip of crispy bacon would make our Waffle House All-Star Special breakfast even more special. The RS7 goes to ten while the RS6 goes to eleven, maybe, but they both rock our world. The RS7 is meant for the far wider buying audience worldwide, not just for western European family bombing runs, as with the RS6 Avant.
But, hey, this RS7 simply hurtles down the road in a singularly sexy way. And if you really want this bodystyle - and who could blame you? - the RS6 Avant doesn't really even matter anyway. After a full day on perfect dry and warm Swabian two-lanes driving this Audi very hard, we barely thought about it at all.

The Audi R8 doesn't need turbos to visit Jay Leno's Garage

When Audi launched the original R8 in 2006, it caused a sensation. For its second go at the model, Audi skipped the V8 and went straight for ten-cylinder power in two states of tune: the V10 and the V10 Plus. Of course Jay Leno had the more potent of the two visit his garage. In V10 Plus trim, the Audi makes over 600 horsepower – all from a naturally-aspirated V10 in a segment increasingly dominated by turbocharging. Rivals like the Mercedes-AMG GT, Porsche 911 Turbo, McLaren 570S, and Ferrari 488 have all adopted turbochargers, which makes the R8 something of a modern-day Shelby Cobra, as Leno puts it. See what else he has to say in the video above – and don't forget to watch to the end to see how the launch control works.
