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.

Audi planning RS Q7 performance crossover

Audi resisted getting into the crossover market altogether until it launched the original Q7 in 2005, and held back from producing a performance crossover until it caved first with the SQ5 and then with the RS Q3, both in 2013. And now that the tide has washed over it, Ingolstadt's next plan, according to Top Gear, is to launch a performance version of the new Q7. Though it remains unclear whether it would carry the S or RS badge, the performance-oriented version of the new Q7 will surely benefit from the hundreds of pounds in excess weight Audi managed to trim off the latest model over the one it replaces. Also unclear is whether said hi-po Q7 would go with a diesel or a gasoline engine. The diesel option would more likely go the S route than the full RS, but wouldn't be likely to make it to the States if it were only offered as a diesel. With the SQ5, it's worth noting, Audi offers a TDI diesel version in Europe and a gasoline TSI in North America, so we wouldn't be surprised to see it take a similar approach with the larger model as well. Whatever it does pack under the hood, though, the SQ7 or RS Q7 would be facing some stiff competition from the likes of the Mercedes GL63 AMG, BMW X5 M and Range Rover Sport SVR – not to mention corporate cousins like the Porsche Cayenne Turbo and upcoming Bentley Bentayga – while giving the Volkswagen group a bigger slice of that exclusive but expanding pie.

Malaise Era All-Stars

A few weeks ago, we bid a fond happy 40th anniversary to the automotive dark ages of 1973-84 that have come to be known as "The Malaise Era" - the performance ice-age when 160 horsepower was a lot and a 0-60 time of under 10 seconds was remarkable. Like music in the 1980s, everything in automobiledom didn't suck, however. There were a few bright spots. Here are five of our favorites:
