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.

VW Sport Coupe Concept GTE 'marks beginning of a new design era' [w/video]

You didn't think that Volkswagen was going to come to Geneva armed only with a bunch of European-market minivans and wagons, did you? Of course not. Last week VW gave us our first glimpse at a new show car for the Swiss auto expo, and here it is in full: the Volkswagen Sport Coupe Concept GTE. Set to be unveiled at the Geneva Motor Show this week, the Sport Coupe is envisioned as a successor to the current CC, but beyond previewing a specific model, this concept showcases a new design language that's set to characterize all new VWs to come. And judging by how good it looks from the images in the slideshow above, that could prove to be a very good thing indeed. The concept strikes us as the sleekest iteration yet of the company's flexible MQB architecture that already underpins vehicles as small as the Golf and as large as the new Skoda Superb. It's larger than the current CC in every dimension but height, and pushes the wheels further out on a longer wheelbase. And with a liftgate at the back instead of a trunk, it strikes a form more similar to the Audi A7 than the Passat-based CC. As with recent past concepts, VW has taken the opportunity to showcase its hybrid powertrain technologies, fitting the Sport Coupe with a plug-in hybrid system that couples a 3.0-liter turbocharged V6 to a pair of electric motors and a six-speed dual-clutch transmission. The internal combustion engine drives 295 horsepower and 369 pound-feet of torque to the front wheels, while an electric motor integrated into the gearbox contributes another 54 hp and a second one kicks in 114 hp at the rear. Juiced by a lithium-ion battery housed in the center tunnel and offering all-wheel traction, the combined output of 374 hp is said to be capable of propelling the concept to 62 miles per hour in five seconds flat and on to a top speed of 155 mph. It can travel for 32 miles on electric power alone and on to an overall range of 745 miles, netting the equivalent of 118 miles per gallon on the European cycle. Inside, the four-seat cabin is laden with digital displays: there's a 12.3-inch unit – dominated by the speedo and power meter – in place of a conventional instrument cluster. The center stack incorporates a 10.1-inch infotainment display, and the rear-seat passengers have access to another 12.3-inch display at the back of the center console and another pair of 10.1-inch displays in the seatbacks.

Porsche 911 and Nissan 350Z get smoked by unlikely hero

So a Nissan 350Z Procharger and a current Porsche 911 GT3 drive onto the Autobahn together - stop me if you've heard this one before - and they decide to race. We're not sure how much power the Z is packing, but the stock model topped out at 306 horsepower on the last year of its run in 2009. And if that's a stock GT3 then it will be rocking something like 475 horsepower. So the Z and the GT3 give it a racing go, and just as one of them starts to pull away they're both overtaken by one of the most unlikely dark horses you could imagine. It's a really short video and we won't spoil the surprise, so check it out above.
