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 says gas-electric Q7 E-Tron PHEV coming to US, China

That 166 MPGe diesel-electric Audi Q7 E-Tron Quattro we wrote about last week from the Geneva Motor Show? The US might eventually get those, too. With one important change. Audi disclosed details about the upcoming Q7 E-Tron Quattro SUV plug-in hybrid at the Geneva show that were truly impressive. The model will be able to go as far as 35 miles on electric power alone and will have a fuel-efficiency rating of 166 miles per gallon equivalent. The 373-horsepower beast will also be able to go from 0 to 60 miles per hour in about six seconds. Like we said, impressive. Now, we're finding out from Automotive News Europe that not only will the model debut in Germany next year, but the US and China will get versions as well. The difference? Whereas the standard European version pairs a 3.0-liter six-cylinder diesel engine with an electric motor, our version will use a 2.0-liter turbocharged gas engine as its non-electric mill, said Automotive New Europe, citing comments from Audi development chief Ulrich Hackenberg in Geneva. No word on when the US will start seeing its version of the Q7 E-Tron, so we'll just have to take a look at Audi's press release below from earlier this month for full details on the diesel Q7 E-Tron.

GRAND-AM, IMSA announce deal to bring DTM racing to US

It won't be until 2015 at the earliest, but the International Motor Sports Association (IMSA), Grand-Am and the Internationale Tourenwagen-Rennen have agreed to a licensing and cooperation deal that could bring a version of Germany's DTM series to the US.
When the American Le Mans Series and Grand-Am are officially combined next year, the resulting body will be called United SportsCar Racing (USCR). IMSA will be the sanctioning body for that series, and DTM races could be run as support events. It was also suggested by an ALMS chief that DTM races could be standalone or join NASCAR and IndyCar weekends.
With the so-called DTM America finally agreed to, there is now a way for manufacturers to run the same DTM-type cars in Europe, the US and Japan - last year Japan's Super GT series agreed to adopt "the basic technical regulations" of DTM for the GT500 class, the top class in the series. That already puts six manufacturers in play: Mercedes-Benz, Audi and BMW that run in Germany's DTM and Honda, Nissan and Lexus that run in Super GT. The DTM oversight body has invited American brands to Germany for the opening round of the 2013 season, and will begin actively courting their participation in the US series. Check out the press release from Audi with comments on the deal below.
