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.

Porsche accused of using steering inputs to cheat on emissions tests

Last week, the German transport authority KBA announced it was investigating Porsche and Audi for cheating on emissions tests. Wirtschaftswoche, a German economic publication, says the KBA's investigation focuses on a system that uses steering inputs to determine whether or not the car is being tested. While Audi has recalled 24,000 models, Automotive News reports that currently Porsche denies any wrongdoing. According to KBA, if the affected cars measured a steering input of 15 degrees or more, they would emit excess nitrogen oxide emissions. It's important to note that this is different than Volkswagen diesel CO2 emissions. The cars broke European strict emissions standards, so it's unclear what impact this has on cars in the US. Audi has recalled the A7 and A8, though it's unclear which Porsche models the KBA is investigating. Fifteen degrees is a small amount of steering input. The wheel can move that much just to move around a pothole or bump in the road. Essentially, if you're driving, you're moving the wheel at least 15 degrees in one direction or the other. If these allegations turn out to be true, it's going to be another blow to Volkswagen, Audi, and Porsche. While public trust in Volkswagen is supremely low, for the most part, Porsche's image has remained fairly clean. NOx emissions don't have as big of a long-term effect as CO2, though they're still bad for humans.

Chevy Corvette Z06, Ford F-150 Raptor join Lego Speed Champs

Get ready to park some performance machines on your desk: Lego's 2016 line of Speed Champions kits will add seven new vehicles for next year, according to an update to the database Brickset. These include some serious muscle like a Chevrolet Corvette Z06 and Ford Mustang GT. There's also a listing called "Chevrolet Camaro Drag Race" and a very cool combo titled "Ford F-150 Raptor Ford/Model A Hot Rod". Fans of European performance don't need to be jealous, though. The database shows a kit called "Porsche 919 Hybrid and 917K Pit-Lane." Plus for fans of the Four Rings, the Audi R18 E-Tron Quattro and R8 LMS Ultra are also getting their own Lego models. Fourtitude appears to have some leaked shots, if you want to see what these kits will look like. Lego has partnered with Porsche, McLaren, and Ferrari and offers Speed Champions kits for vehicles like the Porsche 918 Spyder, McLaren P1, Ferrari 458 Italia GT2, and LaFerrari. The models in the series aren't as heavily detailed as the massive Mini Cooper or Volkswagen Bus sets, but they make up for that in value. The individual cars retail for a fairly affordable $14.99. The Formula One playset tops the current range at $99.99, but it comes with a truck, racecar and team figures.
