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.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.

Next VW GTI to get 10-speed dual-clutch gearbox

Following on Volkswagen's official announcement that it was working on a ten-speed, dual-clutch transmission, Auto Express has it on "good authority" that the new transmission will end up in the next GTI, GTD and Golf R. The brand's current seven-speed will be retained for lesser eight-generation Golfs. While the new gearbox won't be limited to just the higher-end Golf range, the new hatchback, expected in 2017, will be the first to get it, Auto Express reports. The new DSG is the same size as the Volkswagen Group's seven-speed dual-clutch, and will easily fit into VAG's MQB platform, so we should expect it to filter into the rest of the Group's vehicles, much like the seven-speed 'box has. The ten-speed is likely to see applications beyond even the small cars of the MQB platform. The gearbox can handle 405 pound-feet of torque, according to AE, making its application in larger offerings such as the gas-powered MLB cars and crossovers a likelihood. Beyond the new gearbox, Volkswagen is also toying with mild-hybrid tech for the standard Golf and better batteries for the e-Golf. As we said, expect the new Golf to arrive in European markets in 2017, with the current Euro-market Golf getting updated next year. As for the US, we wouldn't be surprised if VW followed the trail blazed by the Mark 7, with a North American arrival for the eight-gem Golf slated for a year or so after sales in Europe begin.
