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 Allroad Shooting Brake is a TT peep show

What you're looking at here is the almost-here third-generation Audi TT. Just compress the suspension a bit to take away its Allroad pretensions and rake its backlight to align better with the previous generation's aesthetic, and you're pretty well there. What you're looking at officially, of course, is the Audi Allroad Shooting Brake, a four-seat E-Tron hybrid showcar powered by Audi's venerable 2.0-liter TFSI four-cylinder (good for 292 horsepower) backed by a 40-kW electric motor and a secondary 85-kW motor acting upon the rear axle to provide low- and moderate-speed drive. The latter also provides through-the-road Quattro all-wheel drive when extra traction and power is called for.
All-in, Audi says the Allroad Shooting Brake's ETron powertrain is good for 408 horsepower and total system torque of 479 pound-feet, enough to haul the 3,500-pound German to 62 miles per hour in 4.6 seconds and up to a governed 155 mph. Despite that tidy performance, Audi says the Allroad Shooting Brake offers robust fuel consumption of 1.9 liters per 100k, equivalent to 124 miles per gallon, with a bladder-busting range of 510 miles.

Audi RS6 Avant vs. Vauxhall VXR8 Supercharged in wagon battle

The performance station wagon is the mature person's muscle car. As we get older, it's natural to add things like spouses, kids and dogs to our lives and each one necessitates a little more space. That doesn't mean we want to give up spirited driving though, and a quick five-door offers a great balance between needs and wants. In the latest video from Evo, we take a look at two, muscular European estates to see which is faster around a track.
Richard Meaden pits the Audi RS6 Avant and Vauxhall VXR8 Supercharged against each other; seeing that the cars go about utilizing their massive performance in very different ways. The RS6's all-wheel drive and luxury interior make it more of a scalpel around the track compared to the Vauxhall's rear-wheel drive hammer. Both offer the driver the chance to create some very smoky powerslides, though. Sadly, neither of these muscle wagons are available in North America, but scroll down to get a taste of them in the video.
