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.

Will the Mission E be the world's first must-have EV?

The Porsche Mission E concept was recently green-lit for production and has a tentative production date just before the end of the decade. With the recent onslaught of all-electric technology, the question remains: Which automaker will release the first must have all-electric EV? Tesla has clearly gained experience in testing the worldwide appetite for luxury, six-figure EVs, having sold its 100,000th vehicle in just three years and six months. But it remains to be seen if automakers can truly manufacture the ultimate green driving machine. Audi has shown its R8 e-tron but acknowledged that it will be produced in only limited quantities. On the other end of the spectrum, vehicles like the Chevy Bolt and BMW i8 are being produced for mass consumption, but will they satisfy the enthusiast who is looking for more than a commuter car? Tesla's Model S has certainly raised eyebrows and collected accolades with "ludicrous" level straight-line performance, but how well will the vehicle stand up to long-term ownership for enthusiasts? Porsche has dismissed any notions of autonomous driving in its vehicles, suggesting that it will try to stay close to its high-performance roots. This would seem to suggest that despite all the forecasted performance cred of the Mission E – 582 horsepower, 0–60 in 3.5 seconds, and a 310-mile range – potential buyers may not be getting the latest and greatest in gee-whiz-bang autonomous technology. And while Porsche has offered that future iterations of its 911 and 718 may in fact use hybrid-assisted drivetrains, the execution of a true, mass-produced, all-electric sports sedan remains to be seen. One thing is for certain, unlike start-ups like Tesla, the larger, more established manufacturers have larger budgets and more time to invest in R&D. Consumers have raised expectations from the more mature automakers in terms of reliability and the overall finish of their products. The arrival of the Mission E production car may introduce us to electric sports sedans that emphasize performance over efficiency while still eliminating its carbon footprint.
