Mercedes considering Audi Allroad rival

The Audi Allroad is something of an anomaly in the automotive world. Its competitors are limited to the recently released Volvo V60 Cross Country and perhaps the far cheaper Subaru Outback. The lifted premium wagon hasn't exactly done great for Audi, only selling a few hundred examples each month. Its best sales year was 2013, and even then, only 5,300 left US showrooms. Despite these limited prospects, word from Australia is that Mercedes-Benz is looking at launching its own competitor to the Allroad. "We are looking at every single niche, so we are studying this [Allroad] at the moment, but it is not confirmed," Matthias Luhrs, VP of sales and a member of the product management at MB, told Motoring.com.au. "We are looking obviously at C-Class and E-Class, but no confirmation at the moment." Fortunately, Luhrs recognizes that the Allroad isn't exactly a smash in the US. "In the US, no matter how long, short, high ... they don't like station wagons," Luhrs said, while adding that the Allroad concept is "developing quite successfully" in Italy and southern Europe. And for those hoping for a lifted C- or E-Class sedan, Luhrs also put the kibosh on that, saying, "We are not studying that." So what does this tell us? Well, it's still far from a sure thing that Mercedes will launch a lifted C-Class or E-Class Estate. And even if the company does go ahead with it, like the rest of the brand's long roofs (E-Class aside), don't expect to see it on US roads.

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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models.
