VW TDI ads star four 'salty' ladies and a stinky dog named Tuna

The Kim Kardashian sex tape just keeps on giving: it brought the Three Golden Sisters to our attention, and now Volkswagen has used their comedic, Bronx grandmother schtick to promote its TDI engines. The ads are another round in the fight against the malicious perceptions of diesel – like how they're slow and loud (they aren't), that it's hard to find a station to refill (it isn't), and that they stink (they don't). Tanner Foust makes an appearance in one spot to dispel the notion of sluggishness, and Tuna the Dastardly Dog proves that she (or he?) can outstink a diesel any day. You'll find Tuna in the ad above, the other three ads are below. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

VW teases GTI Supersport Vision Gran Turismo concept

Volkswagen was among the first to demonstrate its Vision for Gran Turismo with the GTI Roadster concept, last year. And now it's gearing up to release another one. Previewed in the video clip above and the images in the gallery below, the new GTI Supersport is once again conceptually based on the German automaker's iconic hot hatch. But instead of a roofless design rendered in red, this one has a fixed roof with pseudo NACA ducts and white bodywork, along with twin nostril air extractors in the hood, a giant carbon-fiber rear wing and diffuser, and large side vents. In short, it looks like it'll be awesome, and we'll likely see the full thing before too long – so watch this space.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
