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 A7 getting nip and tuck

It's been less than two years since the Audi A7 first went on sale in the US, but European buyers have been able to enjoy the sleek and stylish hatchback for twice as long. As such, Audi is preparing to give its A7 a mild refresh with tweaked exterior styling, but we're also expecting some of the features found in the all-new 2015 Audi A8 to possibly trickle down to the A7.
From what we can tell in these spy shots, the A7 is getting a minor facelift that includes a restyled front fascia and new headlights, which will likely boast Audi's new Matrix LED system. At the rear of the car, similar changes have been made with a fascia that now gets integrated outlets and different taillights that have a Lamborghini-like display.
Not apparent in these images - but still a good bet for production - we'd expect to see the new A7 get some of Audi's updated engines or new driver assist technologies. No definite word as to when we'll be seeing the refreshed A7 in person, but considering how close to production ready as this car seems to be, our bet is on the upcoming Geneva Motor Show.

Audi plans RS3 for US

Rejoice, performance-car fans. The Audi RS3 (pictured above) is probably coming across the Atlantic. If that happens, the US-market RS3 will likely be a sedan, not the five-door body style offered in Europe. Hot hatch fans might shed a tear at this news, but we'll the RS3 any way we can get it. Audi of America CEO Scott Keogh feels the same way. "We really, really want the RS3," he said to Automotive News. "I'm very confident we'll see that car in the market. That's as far as I'm going to go. In Europe, the RS3 Sportback packs a 2.5-liter turbocharged five-cylinder with 362 horsepower and 343 pound-feet of torque mated to a seven-speed dual-clutch gearbox. That grunt get to the ground via a torque-vectoring all-wheel drive system that can route up to 100 percent of the power to the rear wheels when necessary. The sprint to 62 miles per hour goes by in just 4.3 seconds. Of course, a tiny, hardcore sedan isn't on every buyer's shopping list. For those who want a little more room with their luxury, the Q8 is also on the way. "That is absolutely a car that we will see in the United States," Keogh said to Automotive News. The big crossover shares its platform with the next Q7, but will have sleeker bodywork similar to vehicles like the BMW X6 and Mercedes-Benz GLE Coupe. The Q8 is slated to launch in 2017 with US sales following the European debut. Recent rumors suggest that a fully electric E-Tron version could be part of the lineup as well. Audi's American arm isn't as crossover crazy as some other automakers, however. According to Keogh, the tiny Q1 CUV might not come to the US because it's not the right fit for the market.
