Next Audi A7 redesign will include more traditional rear end

A report in Automobile says that Audi is rethinking the design of the next A7. Audi told Car and Driver that owners "have trouble with the radical tail of the A7," so its model-defining rear end will give way to something more traditional. Automobile is light on specifics of the redesign, but the general direction is "a lower, wider, and more expressive shape." The philosophy behind the dimensions and styling is a "C/D shift," meaning Audi wants to give its C-segment hatchback the bearing, gravitas, and visual delight of a D-segment vehicle. That would help the A7 stand out from its in-house competition, and could make for higher transaction prices. Having heard about different design directions from Audi for years without much in the showroom to back it up, we could define what we'd love to see in two words: more Prologue. This is Audi, so you know the next A7 will be packed with tech. We expect an emphasis on touchscreen interfaces, a digital dash cluster a la the TT that moves with the steering column, a HUD with night vision, and an MMI system a few more steps down the evolutionary trail. Engines will see some upgrades like the addition of a plug-in hybrid, the excellent 2.0-liter, turbocharged four-cylinder getting a 74-horsepower e-boost assist to 326 horsepower, the 3.0-liter V6 slated for the S7 rising to 500 hp, and the 4.0-liter V8 in the RS7 pumping out 575 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.

Audi rumored to ditch Le Mans, DTM for F1

If you've been scratching your head wondering how - between Audi and Porsche - the Volkswagen Group could possibly support two rival top-tier LMP1 programs at Le Mans and the FIA World Endurance Championship, but stay out of Formula One entirely, you're not alone. In fact, Porsche was said to have been eying an F1 entry if Audi had internally blocked aspirations to return to Le Mans. But according to the latest rumors, it's Audi that's now preparing to shift away from endurance racing and onto the grand prix circuit.
Word has it that, following internal pressures from within the VW Group, Audi is finally gearing up for a full assault on F1. It's said to be developing a new six-cylinder turbo hybrid power unit - potentially at its new racing headquarters in Neuburg - and, in an expanded partnership with Red Bull, either take Renault's and Infiniti's places with the Red Bull Racing team or take over the Toro Rosso team entirely.
Although Ingolstadt has not campaigned in grand prix racing since the pre-war days of the Silver Arrows, it was said to have been the impetus for the FIA's push a couple of years ago for new four-cylinder engine regulations until Audi bailed on the idea altogether and F1 went for six-cylinder engines instead.
