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.

Daily Driver: 2015 Audi S7

Daily Driver videos are micro-reviews of vehicles in the Autoblog press fleet, featuring impressions from the staffers that drive them every day. Today's Daily Driver features the 2015 Audi S7, reviewed by Seyth Miersma. You can watch the video above or read a transcript below. Watch more Autoblog videos at /videos. VIDEO TRANSCRIPT [00:00:00] Hi, all. This is Seyth with Autoblog. I'm here driving the 2015 Audi S7. I'm caught in a kind of annoying, normal, end-of-the-work-day suburban traffic right now, but even that helps to illustrate the point that I'm trying to make about the S7, is that it really is one of the best all-around grand touring cars that you can buy. A really, really good grand tourer has to do three things. [00:00:30] One, it has to look amazing. It has to feel really special inside and out. The second part is that it's got to be a great long-range cruiser. It needs to be powerful on the highway, be able to be very comfortable and quiet if you're taking it long distances, kind of like your typically Autobahn car. Three, and I think this is really difficult with the second one that I mentioned, I think that grand tourers have to be really great at driving like sports cars. [00:01:00] You're going along and you're touring on the highway and you know that a really great road is coming up. The car should be able to get off on that road and handle like something much lighter and still have that great cruising character. That's one of the reasons why I've always liked the entire Audi A7 line, but especially this S7 because the A7 itself in all of its guises is really a pretty great cruiser and a really practical all-around car with the space in the hatch [00:01:30] and reasonable room in the back seats. The S7 with the turbocharged 4.0-liter V8 making 420 horsepower and 406 pound-feet of torque really amps up the sportiness. Now don't get me wrong, the S7 is far from a sports car. It's not very light. It's got a long wheelbase. It is nimble, especially with Quattro, but it doesn't feel especially nimble. It doesn't want to change directions super quickly. It splits the difference between the two. That being said, [00:02:00] when you get up to some of your favorite roads, it doesn't disappointment you either because of all the power and grip and some pretty decent sporting character available. Of course one thing that you do lack in a big GT like this S7 vs.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.
