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.

Will Audi's e-tron SUV's range match the Tesla Model X?

Tesla may soon get some competition from across the Pond when it comes to battery-electric SUV supremacy. Volkswagen's Audi division is preparing an SUV sized between its Q5 and Q7. And the company is suggesting that the model's single-charge range may challenge that of the Model X. Audi's battery-electric SUV, which was first shown off in a concept version at the Frankfort Auto Show in 2015, may start sales as soon as next year. More importantly, the model could have a single-charge range of more than 300 miles, UK's Autocar says, citing an interview with Audi executive Dietmar Voggenreiter. Granted, that estimate is likely for Europe's more generous NEDC cycle, which would put the range at closer to 250 miles by US Environmental Protection Agency (EPA) standards. Still, 250 miles would beat the 200-mile range of the base-model Tesla Model X and would be in spitting distance of the 100D model's 295 miles. What that means for US customers - price, on-sale date, and range - is unclear. Audi spokesperson Amelia Fine-Morrison, in an e-mail to Autoblog, said it was "too soon to confirm the details," and that the automaker would disclose more information closer to the official launch date. Still, Audi has said it looks to have as much of 25 percent of its global offerings be electrified by 2025, so this will likely be a big step towards that goal. Then there's the question of how big the domestic market will be (not to mention how much the Audi SUV EV will cost). During the three months ended Dec. 31, 2016, Tesla delivered a quarterly-record 9,500 Model X vehicles, so there will obviously be high-end demand for an electric SUV from an established brand like Audi.

VW to unveil diesel-electric Twin-Up! in Tokyo

We've received multiple reports that Volkswagen will be bringing a diesel-electric concept to the 2013 Tokyo Motor Show, set to take place later this month. The car, called the Twin-Up!, is based on the Up! city car, with some sources claiming this is a thinly veiled concept that will eventually enter production.
According to Automotive News Europe, the Twin-Up! will reportedly return 214 miles per gallon on the US cycle by combining an 800-cc, two-cylinder diesel and an electric motor. It will also boast plug-in capabilities, and will be able to cover 30 miles on electric power alone.
Autocar has a more complete picture of the Twin-Up!'s powertrain, though, claiming it's a modified version of the hybrid system found in the Volkswagen XL1. The Twin-Up! will get a more potent, 47-horsepower electric motor to the XL1's 27-hp unit, but will retain that car's 47-hp turbodiesel. The battery pack will also grow, from 5.5 kilowatt hours to 8.6 kWh. Both of these increases are necessary due to the increased weight of the Twin-Up! - it's some 900 pounds heavier than an XL1.
