Audi A3 E-Tron is a look at battery-operated things to come

Audi officially unveiled the A3 Sportback E-Tron at the 2013 Geneva Motor Show. While not a production model, the plug-in hybrid gives us a good glimpse at what the German automaker has in store for future products. The five-door gets around thanks to parallel hybrid drivetrain comprised of a turbocharged 1.4-liter four-cylinder engine and a small electric motor integrated into the vehicle's six-speed dual-clutch transmission. While the four-cylinder churns up 150 horsepower and 184 pound-feet of torque, the motor contributes 100 horsepower and 242 lb-ft of twist. All told, the design allows the E-Tron to serve up its full power from just 1,750 rpm.
An 8.8-kWh lithium-ion battery sits under the floor beneath the rear seat, complete with a liquid cooling system designed to keep the pack in its optimum temperature range. The A3 Sportback E-Tron can be charged in as little as 2.5 hours with a 3.6-kW charger, yielding an EV range of up to 31 miles. The machine can also travel using the electric motor, ICE or a combination of the two for a total range of 584 miles. Check out the full press release below.

2016 Audi A6

After dodging light traffic for more than 10 miles at speeds never exceeding 85 miles per hour, the left lane of the derestricted autobahn ahead of us finally opens wide. This is the opportunity we've been waiting for, and we bury the accelerator against its stop and hold it there. The transmission attached to the turbocharged four-cylinder of our 2016 Audi A6 drops a couple gears and begins an arduous battle against aerodynamic drag.
The sleek sedan cuts through the wind effortlessly up until about 125 mph, after which the speedometer needle slows noticeably as the outside world continues to blur. By 145 mph, there's no longer a discernible feeling of acceleration, yet the bright-orange speedometer needle continues its climb. Finally, the speedometer nearly reaches 160 before we are forced to firmly brake and return to saner speeds because of traffic looming ahead.
Automakers routinely host us in Europe and elsewhere to sample their wares in a much less restrictive driving environment. Which explains why we find ourselves standing in Dresden, Germany, a stunningly beautiful 800-year-old city along the Elbe River, overlooking Audi's latest executive express.

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.
