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.

The hottest modern sports cars rendered as rally racers

The modern-day World Rally Championship a monumental amount of fun to watch – I should know, as I recently was lucky enough to head to the UK to watch WRC Wales Rally GB – but even the most monstrous of the current WRC cars are based on fairly pedestrian European hatchbacks. Back in the heyday of rally, the Group B era in the 1980s, much hotter cars were the basis of even more incredible competition machines, for the most part. Take the exotic Ford RS200, or the Lancia Delta S4 with its twin-charged engine. And the hatchback-based Group B cars were bonkers, too. So what would some of our favorite modern cars look like if Group B had never ended? A British site named CarWow hired an artist to reimagine everything from the Rolls-Royce Wraith to the Porsche 911 as a retro-inspired rally car, and they were kind enough to let us share the results in the gallery above. The gallery features an Alfa Romeo Giulia in Martini livery, an Audi TT in classic Ur-Quattro colors, a Fiat 500 Abarth sporting massive flares and a hood blister full of auxiliary lights, a new Ford Mustang in RS200 livery, a Lancia Delta in Alitalia colors, a Porsche 911 in Rothmans livery, a Renault-Alpine in classic blue, a Rolls-Royce Wraith tribute to the Jules cologne Corniche Coupe, and a relatively modern-looking VW Touran. So far, the favorite around the office is the incredible Mercedes-Benz S-Class that is an homage to the wonderful 300 SEL 6.8 AMG "Red Pig" that essentially put AMG on the map. Check out the gallery above and see which one you like the best. Related Video:

VW chair says component cost decrease keeps him confident of EV success

Volkswagen AG is in the middle of implementing a comprehensive electric vehicle strategy, one that we've been documenting for a long time. The Group stands ready to offer dozens of plug-in vehicles in the coming years if it feels there is sufficient demand and believes that selling a million EVs in Germany by 2020 is reasonable. That would be a solid number, but remember that VW sold over 5,923,000 passenger cars around the world last year, and the group as a whole sold over 9.7 million. At the company's annual Media Conference and Investor Conference in Berlin recently, the chairman of the board of VW AG - surrounded by some decidedly non-green examples of the VW Group's vehicles (some absurd new Bugatti, for example) - took some time to put the company's EV plans into focus. The upshot is that Dr. Martin Winterkorn is still guiding his electromobility ship into new waters, saying that "many more [plug-in] models will follow." Winterkorn said there are three main reasons he is confident in the ability of VW (and Audi and Porsche, at the very least) to push EV sales upward. Batteries are getting better, he said, and if the ranges can be extended, then customers are happy. But the real secret lies in reducing component costs. He said (as translated): It is important to look at the cost of the components: the battery technology, the electric motor and the electric components. Whenever you go into volume production, you of course have economies of scale. In two to three years' time, if we are able to achieve the goals we are setting for ourselves with cost and reach sufficient volume, I do believe that we can achieve two to three percent [market share] within VW Group. So, hitting a million EVs by 2020 is reachable. With the e-Golf and the e-Up off to excellent sales starts, we're willing to be confident as well.
