Audi rumored to leave top-tier endurance racing after 2017

Volkswagen's ongoing diesel scandal is turning out to be an expensive problem for the German automaker. With a recent settlement expected to cost the company up to $14.7 billion, the company is scrambling to find ways to save cash. In light of this, Audi could be pulling out of the highest class of endurance racing, which it has dominated for years. A report from Germany's Auto Motor und Sport, indicates that Audi has already finalized the automaker's departure from the World Endurance Championship's top-tier LMP1 class after the 2017 season. Another report by Autocar cites an unnamed insider to corroborate the LMP1 exit rumors. The report fingers the VW Group's ongoing diesel scandal's financial fallout as the main culprit for Audi bowing out of LMP1. The move to could also be due to the group's decision to move away from diesel technology. Audi's LMP1 car, the R18, utilizes a V6 turbo-diesel engine. The Porsche 919 Hybrid, on the other hand, uses 2.0-liter turbocharged V4 engine that runs on gasoline. Audi has won the legendary 24 Hours of Le Mans 13 times since 1999, making Audi an unstoppable force in endurance racing. Porsche, Audi's corporate sibling, reentered endurance racing with a LMP1 competitor of its own in 2014 and won the constructor's championship last year. Audi's decision to leave LMP1 could give Porsche a shot at creating its own Le Mans-winning dynasty. Autocar reports that Audi is expected to continue fielding cars in other WEC classes, like GT3 and GT4, and perhaps the brand will even enter Formula E. We reached out to Audi for some clarification on the matter and a spokesperson stated that the rumors were "pure speculation at this point."

Audi Q7 plug-in hybrid spied, Porsche powertrain possible

It's no secret that a new Audi Q7 is on the way. The replacement for the aging, three-row luxury CUV has already been spotted once, in December of 2013. Now, though, we have images of the second-generation model lapping Germany's Nürburgring Nordschleife, and it just happens to be showing a feature we reported on at the end of July - a plug-in-hybrid powertrain.
Given away by its high-voltage stickers on the window and a spare door to hide the charger - note how both the driver and passenger sides sport an access point - our spies snapped a series of photos, and put forth the compelling idea that the new Q7 would use the PHV system from the Porsche Cayenne S E-Hybrid.
If that's the case, that should mean at least 320 horsepower from a 3.0-liter, supercharged V6, while an electric motor chips in a further 95 ponies for a total system output of 416 hp.

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.
