LTE technology puts Audi in the driver's seat

The recently-launched Audi A3 Sportback was first-to-market with Long Term Evolution (LTE), or 4G, and LTE integration for connectivity on the move is an idea swirling all through the automotive world. Automakers see the faster speeds and faster responses of LTE compared to 3G as making it possible to one day have streaming video, cloud gaming, more intensive apps and even a virtual office with videoconferencing in your car. It will also enable more progress in machine-to-machine (M2M) adoption, giving cars a real-time ability to speak to one another and to infrastructure.
A video by Audi Deutschland looks at what might be possible not only for the average driver in an LTE-equipped car, but how a professional chauffeur might make the most of a car that can help him get his VIP passengers from carport to red carpet safely and on time. You can watch it below.

Next-gen Audi A5 shows its heavily camouflaged face

The new Audi A4 is set to launch at the Frankfurt Motor Show in September, so it shouldn't come as too big of a surprise that an updated A5 is on the way, as well. Our spies just caught the coupe testing for the first time while wearing heavy camouflage from nose to tail. Despite the concealment, some details are possible to make out, especially when comparing the two-door design to the previously spied A4. Audi is further differentiating the designs, and the A5's front end is significantly changed based on these photos. The headlights appear larger and more acutely angled than the narrower units on the sedan. Also, the lower bumper gets square intakes at each corner and the shape creates an additional opening in the center for the coupe. In profile, it's easy to notice the quicker sloping roof and smaller side windows. Only the rear end of the two models seem to share many significant cues. The new A5 reportedly rides on the same MLB Evo platform as the upcoming A4 to shed around 200 pounds. The two models might not launch at the same time, though, and the coupe could join the lineup somewhat later. S5 and RS5 variants are expected to join the range further down the line, too.

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.
