Audi A3 E-Tron plug-in hybrid set to whiz into Geneva

The Audi A3 E-tron, which we drove in prototype form last year, is headed to the 2013 Geneva Motor Show next month. The plug-in hybrid will feature a total of 204 horsepower and 258 pound-feet of torque from the combination of a turbocharged 1.4-liter engine and a 75-kW electric motor. That motor itself is positioned between the internal combustion engine and the machine's six-speed dual-clutch transmission. The setup is good enough to scoot the A3 E-tron to 62 miles per hour in 7.6 seconds and crank out a top speed of 138 mph. Perhaps more impressively, the hatch can whir its way to 80 mph on all-electric power with an EV range of 31 miles.
Audi claims the A3 E-tron gives the world a "realistic glimpse into the future of mobility," so it's a bit unclear if the model will see production. We're encouraged by the specificity of Audi's press release (which is full of stats) and the fact that they don't label this vehicle a concept. You can check out the full press release below and judge for yourself.

Audi R8 V10 Plus vs. Renault Clio Cup racecar will make you go hmmm...

Match up a hot hatch with a supercar of the same vintage, and we'll tell you who will win every time. It's easy, really, as the supercar invariably features a more advanced suspension, stickier tires and most importantly, more power. What if the hot hatch is race prepped, though?
In that particular case, all bets are off. A circuit-tuned suspension, a stripped-down cabin, an ultra-quick sequential transmission and the greatest equalizer of them all, slick tires, are all that's needed to turn the typical hot hatch into a proper dragon slayer.
Perhaps seeking to prove this, Evo has put together an interesting head-to-head between the Audi R8 V10 and a race-prepared Renault Clio Cup. Host Dickie Meaden takes us through each car, highlighting the bits and bobs on both sides which should make this a tight competition. And boy, is this one tight.

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.
