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 introduces frugal, 43-mpg Q7 Ultra in Europe

As Audi's largest model, you wouldn't expect the Q7 (standard 2017 model pictured above) to get very good fuel economy. But the new flagship crossover is a lot lighter than its predecessor. And now the German automaker is rolling out an even more efficient version. In Europe, at any rate. Bearing the designation that distinguishes the most fuel-efficient models that Audi offers, the new Audi Q7 Ultra 3.0 TDI Quattro packs a more frugal version of the 3.0-liter V6 turbo diesel. In Ultra spec, it produces 218 horsepower instead of 272, and 369 pound-feet of torque instead of 443. In exchange, it returns better fuel economy – now quoted at the equivalent of 42.8 miles per gallon (compared to 41.3 for the more potent version). That's not half bad for a crossover this large, even if it is on the European efficiency test, which returns higher numbers than what we're used to in the US. Of course, burning less fuel comes at a bit of a performance penalty: instead of 6.3 seconds, it now takes 7.1 seconds to reach 62 miles per hour from a standstill. Top speed is quoted at just over 134 miles per hour, down from 145. Of course, the E-Tron hybrid will be the most efficient model in the Q7 range, returning the equivalent of over 117 miles per gallon while reaching 62 in six seconds flat. That is, when it starts reaching dealers next spring. The kicker here is that while the hybrid is likely to emerge as the most expensive model in the range, the Ultra is the least. Its base price in Germany comes in at 58,000 euros, compared to 61,890 for the more potent TDI. Combine that with the fuel savings, and the Q7 Ultra is looking like the frugal choice indeed. New Audi Q7 as a highly efficient diesel - The Audi Q7 ultra 3.0 TDI quattro now available for order - Combined fuel consumption is 5.5 liters of fuel per 100 km - Base price is 58,000 euros in Germany An exceptionally efficient diesel version of the new Audi Q7 is launching on the market, which customers can now order: the Audi Q7 ultra 3.0 TDI quattro*. This engine not only reduces fuel consumption to 5.5 liters diesel per 100 km (42.8 US mpg); it also reduces the entry-level price for the Q7 model series to 58,000 euros. Audi will be delivering cars to dealers in Europe starting in September. The efficiency is ground-breaking: The combined fuel consumption of the 3.0 TDI with 160 kW (218 hp) is just 5.5 liters of fuel per 100 km (42.8 US mpg).

Audi A8 super high-tech headlight teased, whole car coming Aug 21

We have to wait one more week before we get to see the 2015 Audi A8 and S8, but it doesn't look like Audi is going to stay quiet until then. After releasing a pair of teaser videos over the last week, it has now released a first detailed picture of the new A8 revealing the trick Matrix LED headlight.
Between the high-beam and low-beam lights, the headlights contain 43 LEDs (not including those for the DRL/turn signal), but the innovative part of Matrix LED system is that a camera can control the high-beam lights - by either dimming them or shutting them off - when other vehicles are detected on the road to prevent the lights from distracting other drivers. Of course the big question remaining is if Audi can get these new headlights to pass the National Highway Traffic Safety Administration and its Federal Motor Vehicle Safety Standards. The taillights also get a cool design with 24 LEDs that use a sequential turn signal
As for the debut of the A8 and S8, we already knew the sedans would be unveiled on August 21 ahead of the Frankfurt Motor Show, but Audi finally made it officially official in a press release, which is posted below. Also be sure to check out the pair of teaser videos Audi has released for these cars recently.
