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.

Audi trademarks SQ2, SQ4, Q9 and F-Tron nameplates

Audi is planning a whole raft of new models for the near future, and now we have further insight into what at least some of those models might be. The German automaker has reportedly filed trademarks for a series of model names, including SQ2, SQ4, Q9 and F-Tron.
Following in the footsteps of the SQ5 performance crossover, the SQ2 and SQ4 nameplates would seem to indicate that Audi is planning performance versions of its upcoming compact crossovers. The Q9 would suggest that a larger crossover is in the works to slot in above the already gargantuan Q7. And the F-Tron name could be used for a fuel-cell version of the A7 or other models, following a similar naming pattern to the e-tron range of electric vehicles.
Of course Audi could simply be filing these trademarks as a safeguard and may not actually build any of these models. But one way or another, it indicates a certain measure of intent exists as Ingolstadt gears up to expand its lineup with 11 new models in the next few years.
