VW recalling 2.64M vehicles worldwide over engine, light issues

Volkswagen is staging a massive, worldwide recall that's already grown from 1.68 million to 2.64 million vehicles and covers three different issues across a number of vehicles. We already reported on 61,000 Tiguans getting recalled over lighting issues - that was just in the US. Globally, however, VW will be recalling 800,000 Tiguans, according to Automotive News, with the focus on CUVs built between 2008 and 2011. The issue with the Tiguan relates to a simple fuse swap, so this is rather unremarkable, aside from the sheer number of vehicles being fixed. The real, troubling issues relate to gearboxes and pickups.
239,000 Amarok pickups (pictured right) are being recalled over fuel leaks, while 1.6 million vehicles are being recalled to swap the synthetic oil in dual-clutch transmissions with mineral oil. Now, the transmission issue is one for the global Volkswagen Group to address, not just the VW brand - vehicles from Audi, Škoda and Seat use the same seven-speed DSG and are covered under the recall, as well.
Why the switch from synthetic to mineral oil? Apparently, using the synthetic oil in a DSG and then subjecting it to stop-and-go conditions or heavy loads in a hot and humid climate can lead to electronic malfunctions, according to a Volkswagen press release. The switch, from the sounds of it, is largely a preventative measure.

A magical, disappearing ad for the hydrogen Audi A7 Sportback H-Tron

It's not quite Tupac appearing at Coachella with Snoop Dogg and Dr. Dre in hologram form, but it'll do for the gearhead set. Audi is looking to make a first impression for its A7 Sportback H-Tron hydrogen fuel-cell vehicle by making as little of an impression as possible. Like the car itself, Audi has, as it says in a video, "created ads that leave behind nothing but vaporized water." Pretty slick. Audi worked with German advertising agency Thjnk, on the campaign, which uses LED lighting and other bits of magic to first show an image of the sedan and then show it disappearing into a cloud of steam, according to Adweek. The publication posted Audi's 58-second video on the campaign (we've embedded a German version of the video for those looking to practice a bit of linguistics). The German automaker first revealed details about the A7 Sportback H-Tron late last year. The all-wheel-drive sedan can go as far as 31 miles on electricity alone. And the hydrogen fuel-cell drivetrain delivers almost 400 pound-feet of torque and a full (hydrogen) tank's range of 311 miles as well as a 0-62 mile per hour time of less than eight seconds and a top speed of 112 mph.

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.
