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 mood at this year’s Paris Motor Show: Quiet

The Paris Motor Show, held every other year in the early fall, typically kicks off the annual cavalcade of automotive conclaves, one that traverses the globe between autumn and spring, introducing projective, conceptual and production-ready vehicle models to the international automotive press, automotive aficionados and a public hungry for news of our increasingly futuristic mobility enterprise. But this year, at the press preview days for the show, the grounds of the Porte de Versailles convention center felt a bit more sparsely populated than usual. This was not simply a subjective sensation, or one influenced by the center's atypically dispersed assemblage of seven discrete buildings, which tends to spread out the cars and the crowds. There were not only fewer new vehicles being premiered in Paris this year, there were fewer manufacturers there to display them. Major mainstream European OEM stalwarts such as Alfa Romeo, Fiat, Nissan and Volkswagen chose to sit out Paris this year, as did boutique manufacturers like Bentley, Aston Martin and Lamborghini. This is not simply based in some antipathy on the part of the German, British and Italian manufacturers toward the French market — though for a variety of historical and societal reasons that market may be more dominated by vehicles produced domestically than others. Rather, it is part of a larger trend in the industry. Last year, Mercedes-Benz announced that it would not be participating in the flagship North American International Auto Show in 2019 — and that it might not return. Other brands including Jaguar/Land Rover, Audi, Porsche, Mazda and nearly every exotic carmaker have also departed the Detroit show. Some of these brands will still appear in the city in which the show is taking place, and host an event offsite, to capitalize on the presence of a large number of reporters in attendance. And even brands that do have a presence at the show have shifted their vehicle introductions to the days before the official press opening in an attempt to stand out from the crowd. In many ways, this makes sense. With an expanding number of automakers, with diversification and niche-ification of models and with wholesale shifts that necessitate the introduction of EV or autonomous sub-brands, there is a growing sense that, with everyone shouting at the same time, no one can be heard.

Volkswagen Cross Coupe GTE concept previews new midsize CUV... again

Volkswagen has taken a big step towards the long-awaited second model to be built at its Chattanooga, TN factory, introducing the two-row Cross Coupe GTE Concept at the 2015 North American International Auto Show. The relatively handsome two-row crossover borrows its basic styling language from the CrossBlue Concept that launched at the 2013 Detroit show (that we later had a brief chance to drive), and the CrossBlue Coupe from that year's Shanghai Motor Show. To be entirely frank, it just looks like a much more production-ready version of the Shanghai concept. The more aggressive elements of that model, like its rear taillights, rounded wheel arches, and aggressive front and rear fascias, have been toned down considerably. In other words, this concept almost wouldn't look out of place on the average road. Changes in the cabin are similarly minor, with the same basic design as the CrossBlue, complemented by a 12.3-inch digital instrument cluster and a 10.1-inch touchscreen display. While it's still quite clearly a concept car interior, it's not hard to imagine VW transitioning this cockpit into a production model. Riding atop the Volkswagen Group's MQB architecture – making it a relative, albeit distant, of cars like the VW Golf, Audi TT and the Euro-market Passat – the Cross Coupe GTE is motivated by a 3.6-liter VR6 that's been mated to not one, but two electric motors (one on each axle). The gas engine offers up 276 horsepower and 258 pound-feet of torque, while the front axle's electric motor generates 54 hp and 162 lb-ft of torque, and the rear can deliver a more robust 114 hp and 199 lb-ft of torque. That cacophony can be easily boiled down to this: the Cross Coupe GTE has a total system output of 355 hp and 280 pound-feet of torque, which is good enough to get the five-seater to 60 miles per hour in six seconds, on to a top speed of 130 miles per hour. As a plug-in hybrid, though, there's more to the Cross Coupe GTE then just its power output. Range plays a big role, and in that regard, this concept is fairly average. It can cover 20 miles when its 14.1-kilowatt-hour lithium-ion battery is charged up. Beyond that, the drivetrain can be set to a number of modes to optimize the behavior of plug-in-hybrid powertrain. In E-Mode, which can be locked in via a battery hold/battery charge mode, all 20 miles of range are available, although the Cross Coupe's driver will only have the 114-hp rear axle electric motor to work with.
