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.

2015 Audi A3 configurator is up and running

Potential customers for the new Audi A3 should set aside some time during their lunch breaks to head over and build their ideal example of the new sedan. The official configurator, complete with pricing and options, has gone live on the Audi website.
Customers can choose from three trim levels (Premium, Premium Plus and Prestige), while each trim can be had with either the Volkswagen Group's familiar 2.0-liter, turbocharged, 220-horsepower four-cylinder or a 1.8-liter, turbocharged, 170-horsepower four-cylinder. Buyers of the 2.0-liter will enjoy Quattro all-wheel drive while power for the 1.8T is channeled through the front wheels only. A six-speed, S-Tronic dual-clutch transmission is standard across the range.
You can check out full pricing on the A3 right here, but as a means of recap, the base Premium trim with the 1.8-liter engine starts at $29,900. A Premium Plus 1.8T starts $32,800 and the Prestige 1.8T will cost $38,700. Adding a 2.0-liter turbo and Quattro increases the price by $3,000, regardless of trim. Those prices don't include an $895 destination charge.

Is Audi readying hardcore final edition R8?

The days may be numbered on the current Audi R8, but if our latest round of spy photos is any indication, Audi's first supercar is going to go out with a bang. This camo'd tester was spotted parked somewhere in Europe, and if doesn't at least belie a faster R8, it certainly indicates that a more aerodynamically intense model is coming.
The tall rear wing is the most obvious aerodynamic change. It's joined out back by a none-too-subtle diffuser and the cannon-like exhausts of the R8 V10 Plus, while the front and side of this particular R8 are home to new side sills and winglets on the lower front fascia.
We'll be keeping our ears to the ground for any more on what looks to be another variation of first-generation Audi supercar. Until then, let us know what you think this car may foreshadow. A new halo model? A gentleman racer? Have your say below.
