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.

What kind of watch do you wear?
Especially today, when wearing a wristwatch is practically obviated by the near-ubiquitous use of cellphones, the timepiece found on one's arm makes a statement about how people perceive themselves.
A sport watch from Nike or Garmin would seem to indicate enthusiasm for athletic pursuit. Inexpensive fashion statements from Nixon or Nooka could signify a love of high design. Splashing out on a true luxury timepiece from Rolex, Bell & Ross or Breitling serves as a sort of human plumage display to connote, "I have thousands of dollars - at least - of disposable income."

2014 Audi R8 officially on sale, starting at $114,900*

After skipping the 2013 model year, the Audi R8 is back for 2014 with a new look, added performance and a slightly higher starting price. In V8 coupe form, the 2014 R8 starts at $114,900 (*not including $1,250 for destination and a $3,000 gas-guzzler tax), but looking at that price, which has risen just $5,900 since the performance coupe first debuted in the US for 2008, inflation doesn't seem to have hit the R8 as hard as some other sports coupes - like, say, the Nissan GT-R.
Opting for the S tronic automatic gearbox will cost $9,100 for all models, while R8 V8 and R8 V10 models still offer the drop-top Spyder model for an extra $13,500. Not available in Spyder form, is the all-new 550-horsepower R8 V10 Plus, which starts at $170,545. Scroll down for the full pricing breakdown of the 2014 R8, which went on sale yesterday.
