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.

Weekly Recap: Porsche embarks on Mission E

Porsche's board of directors approved the company's first all-electric car Friday, signing off on production of the eye-catching Mission E concept that debuted in September at the Frankfurt Motor Show. It's set for launch by the end of the decade. The Frankfurt concept uses lithium-ion batteries to power two synchronous motors that create more than 600 horsepower and provide a range of 311 miles on the European cycle. It's capable of hitting 62 miles per hour in 3.5 seconds and can run the Nurburgring Nordschleife in less than eight minutes. In a statement, Porsche board chairman Oliver Blume called the Mission E the "beginning a new chapter in the history of the sports car." Porsche is backing that up with a roughly $1.1-billion investment that will create more than 1,000 jobs at its facilities in Zuffenhausen, Germany. The company will spend more than $760 million at its main site there to build a paint shop and a new assembly plant. It will also expand an engine factory to make electric motors. Porsche's renewed electric ambitions come as it grapples with fallout from parent company Volkswagen's diesel-emissions scandal. Porsche uses a VW diesel engine in the Cayenne SUV, which it stopped selling in November until a fix is found. Still, Mission E's scheduled landing could be as much as four years away – when Porsche and VW hope their diesel woes will be long over. The electric strategy is clearly a long play to provide its enthusiast owners with an efficient form of sport and luxury as fuel economy and emissions regulations tighten around the world. And if you still can't wrap your head around electric Porsches, the company also just announced plans to make the 911 Turbo and Turbo S even more powerful. Electric propulsion is part of Porsche's future, but for now at least, it isn't everything. OTHER NEWS VW sales crash 25 percent in November Finally, the other shoe dropped. Volkswagen sales plummeted 25 percent in November as fallout from the company's diesel-emissions scandal finally showed up on the sales charts. VW had managed to tread water with flat sales through September (the scandal broke more than halfway through the month) and October. The company stopped selling its 2.0-liter I4 and 3.0-liter V6 diesels as it works to make the engines complaint with emissions rules. VW admitted to rigging its diesel-powered cars so they could pass emissions tests in the United States and around the world.

Porsche turns up boost on 911 range with new Turbo and Turbo S

You didn't honestly think Porsche would stop with just a turbocharged Carrera and Carrera S, did you? No, that'd be silly. Of course Stuttgart had to follow up those two smash hits with a new Turbo and Turbo S. Naturally, both cars build on the 370-horsepower Carrera and 420-horsepower C2S. The base Turbo offers 540 horsepower and starts at $160,195, while the Turbo S packs 580 horsepower and demands an extra $28,900. Adding a folding fabric top to either model will drive the cost of entry up by $12,300, regardless of output. For those keeping track at home, that's a 20-horsepower bump for both vehicles over the previous models, while the Turbo's price jumps by $8,100 and the Turbo S will cost an extra $5,400. In terms of actual performance, the Turbo hits 60 in just 2.9 seconds and will carry on to 198 miles per hour, a one-tenth and three-mph improvement over the current car. Going for the Turbo S will only shave a tenth of second off the 60-mph sprint, although you'll pick up an extra seven mph on the top end. That compares favorably to the current car, which takes 2.9 seconds to get to the magic six-oh and stops accelerating at just 197. The stopwatch improvements are only part of the story. Porsche claims the new dynamic boost function will maintain turbo pressure during sudden throttle load changes, like you might experience when pushing the 3.8-liter, twin-turbocharged flat-six hard. That means snappier throttle response. As with the current 911 Turbo and Turbo S, Porsche's excellent dual-clutch transmission is the only way to fly. This content is hosted by a third party.

Both cars also get Porsche's Sport Chrono Package and Porsche Active Suspension Management as standard, while upgrading to the Turbo S will add Porsche Dynamic Chassis Control and carbon-ceramic brakes. While there's lots of free hardware, we're betting Porsche's options catalog will remain just as robust. As for the design, you can expect the same look shown on the new, turbocharged 911 Carrera, albeit with some Turbo and Turbo S exclusives. 20-inch wheels are standard, with super-wide rubber in the back – Porsche doesn't list tire specs, but the rear hoops are 11.5-inches wide. Both the 911 Turbo and Turbo S will get their big debut at the 2016 Detroit Auto Show. Naturally, we'll have much more then, including live photos from the show. In the meantime, read on for the official press release from Porsche.
