CARB has 20 days to confirm VW's 3.0-liter TDI emission fix

VW's diesel scandal has been in the headlines since last September, but solving the problem it proving difficult. Volkswagen Group has submitted a proposal to the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) to fix about 85,000 vehicles with the 3.0-liter diesel V6 in the US, Reuters reports. CARB now has 20 business days to test if the plan actually reduces emissions. If accepted, VW could finally begin a recall and end the stop sale on vehicles with these engines. In a statement, CARB pledged to, "respond following a thorough and complete review to make sure the plan addresses the presence of the illegal defeat device and follows the necessary environmental, vehicle and public health and safety regulations." Neither CARB nor the EPA outlined the proposed repairs, but Porsche CEO Oliver Blume already suggested the fix for the engine in the diesel Cayenne. Examples from 2013 and 2014 allegedly need a new catalytic converter and software update, and those from 2015 and 2016 only need the improved code. It's not yet clear whether this procedure would work for all models with the 3.0 TDI. While the EPA issued the notice of violation against VW's 2.0-liter four-cylinder diesel in September, the first one for the 3.0-liter V6 came in early November. By the end of the month, the agency broadened the scope to about 85,000 vehicles, including some examples of the VW Touareg, Audi A6, A7, A8, Q5, Q7, and Porsche Cayenne. The affected companies issued stop sales on new models with the engine. Audi eventually admitted to regulators that it didn't disclose three auxiliary emission control devices in the powerplant's code and promised to develop a software update to fix the problem. CARB gave the automaker 45 business days to submit the proposed solution. If accepted, this repair would allow VW Group to end part of the emissions scandal, but there's no guarantee the regulators consent to this solution. Just a few weeks ago, CARB looked at the automaker's plan to fix the 2.0-liter TDI and rejected it, claiming a lack of detail.

This month's deals on wheels: 3 cars with incentives, rebates

On television, they come at you rapid-fire: truck deals, car deals, SUV deals. You don't have time to read the fine print, and many sound too good to be true. What follows are three deals that are both good and true. And check out our entire list of incentives and rebates. VOLKSWAGEN JETTA: With Dieselgate winding down and VW's all-new three-row SUV – the Atlas – winding up, Volkswagen is selling sedans with incentives. The Jetta remains VW's bestseller in the US. If you're looking for an immodest deal on modest transportation, you can do worse than a lease on the 2017 Jetta S. THE DETAILS: Purchase at 0.9% APR (no down payment required, available on new 2017 Jetta models financed by Volkswagen Credit, participating dealers only). At that rate, you could save $1,600 over the life of a loan. Offer ends May 1, but given the tepid market interest in sedans, incentives will probably continue through the balance of the model year. NISSAN TITAN CREW CAB: While some buyers will wait for Nissan's recently announced Titan King Cab, and commercial users will grab the regular cab and 8-foot bed, we'll recommend a lightly optioned 4X4 crew cab with standard V8 power, California-penned sheetmetal and a made-in-America footprint. Nissan's full-size pickup is finally a credible competitor in the pickup segment. THE DETAILS: With $3,500 cash back, on top of whatever deal you negotiate, Nissan is effectively reducing the window sticker of a Titan S crew cab by almost 10 percent. MITSUBISHI OUTLANDER: Some cars show up on buyers' radar, some don't. Some aren't anywhere near the radar room. Mitsubishi's Outlander is one of those. But that doesn't diminish its basic attractiveness, especially for young families looking for an affordable three-row SUV with responsive power and competitive features. Add one of the industry's longest warranties and a compelling deal, and you suddenly have reason to track down a Mitsubishi dealer. THE DETAILS: It couldn't be simpler – negotiate your best deal on a 2017 Mitsubishi Outlander, and then receive a $2,000 rebate; on a remaining 2016, it's $3,000. We'd select a fully-equipped GT 3.0S – AWC, which hooks Mitsubishi's V6 to a conventional automatic (vs. a CVT on lower-priced models) and all-wheel drive. That's a window sticker of about $34,000, and you can count on an aggressive posture by the dealer to get your business. Mitsubishi Nissan Volkswagen Car Buying Buying Guide Truck SUV Sedan

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
