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 execs mulling turbocharged, entry-level R8

The just-launched, second-generation Audi R8 is apparently a pretty fantastic example of Vorsprung durch Technik. While it's sublime to drive, Audi might already be missing some potential sales due to the lack of an true entry-level version in the supercar's lineup. Lending further credence to an earlier rumor about just such a model, company execs are saying to expect an entry-level, turbocharged R8 to launch in the coming years. "It is inevitable that we will go to a turbocharged motor for it at some point," Audi technical development board member Dr. Ulrich Hackenberg said to Motoring. "It would be in this model cycle, to give us a fuller range." The executive certainly isn't mincing words about forced induction, but the V10's position in the lineup is also secure. "It doesn't mean we are not going to do a turbo, but naturally aspirated is here to stay as well," he said. If Dr. Hackenberg's direct assertion isn't enough, Quattro GmbH chief Heinz Peter Hollerweger further clarified to Motoring that the turbocharged engine would slot into the bottom of the R8's range. An unnamed "senior sales and marketing source" within the Audi also said that the company's turbo five-cylinder was among the currently favored choices for the application. The first rumors about the R8 getting a forced induction version arose just a few months ago. At the time, Audi's electrically turbocharged, 2.5-liter inline five-cylinder was considered an option. The model would solve a problem in markets, like China, that severely tax big displacement engines. Customers might not even need to worry about giving up too much performance either. In the Audi TT Clubsport Turbo concept, the powerplant has a total output of 600 horsepower and 479 pound-feet of torque. While 10 fewer ponies than the latest R8 V10 Plus, it would bring 66 lb-ft more twist to the supercar.

Audi highlights headlights on upcoming new R8

Audi is preparing to roll out an all-new R8... but it's not about to reveal the whole thing at once. So in the first in what promises to be a series of teasers, the German automaker is showing off the new supercar's headlights. (Or headlight, we should say, in the singular.) Not unlike the R8 LMX revealed in Paris, the second-generation Audi supercar will incorporate LED headlights with an optional laser high-beam module. Unfortunately since laser headlights are illegal in the United States, the option isn't likely to be offered here. That is, at least, until Audi succeeds in convincing federal regulators otherwise. Although the teaser image above, like the press release below, may shine the light (so to speak) principally on the headlights, the shrouded shape also gives us a (little) bit to chew on. Yes, it will be available in blue, but beyond that we can expect the new R8 to incorporate slightly more angular lines than the model it replaces, with a more pronounced trapezoidal grille up in an overall design similar to the new TT, only more so. But then we already knew that much and more from the undisguised image that leaked out a little over a week ago. Ingolstadt, 2015-02-16 Audi reveals laser headlights for the new R8 - New mid-engine sports car features high-tech headlights - Laser high-beam offers high light intensity and excellent range Audi is revealing the headlights of its new R8* as the first of a number of technology highlights of the top sports car. The R8 uses LED headlights which can be supplemented by a laser high beam lighting module as an option. The new R8 will set new standards among high-performance sports cars – including in its lighting technology. As an option, the latest car development by Audi can be equipped with a laser spot as the high-beam headlight. The special appeal of laser lighting is that it uses high-intensity laser diodes, which generate a lot of light energy from a very small component. Compared to LED high-beam headlights, laser high-beams attain nearly twice the lighting range. Each headlight contains one laser module that operates with four high-intensity laser diodes. This module bundles the four intense blue-light laser beams. Then a phosphor converter transforms the blue light into pure white light. An identifying characteristic of the laser headlights is their blue light signature. Standard equipment in the new R8 includes an LED headlight system.
