Porsche CEO outlines Cayenne diesel US repair proposal

Porsche has announced a plan to fix the emissions issue on the Cayenne with the 3.0-liter diesel V6, and it includes a software update and the replacement of the catalytic converter on some early examples, according to Reuters. The company believes these repairs are enough to make the SUVs emissions compliant, but the automaker's proposal still needs approval from the Environmental Protection Agency and California Air Resources Board before it can implement a recall. This authorization could come by the end of January. Note that the proposed 3.0-liter TDI plan is separate from the 2.0-liter TDI fix that was rejected by CARB on Tuesday. There are around 13,000 Cayennes on the road that the company needs to repair. Models from 2013 and 2014 would require a new catalytic converter and a software update, but those from 2015 and 2016 would just need the new software. "The technical aspects have all been submitted, we will wait whether there will still be proposals for corrections by the Americans," Porsche CEO Oliver Blume said to Reuters. He wasn't sure how long the repair process would take, but suggested less than half of the affected examples would require the upgraded exhaust hardware. Blume indicated to Reuters that Audi actually created this repair plan. The EPA first issued a violation notice against the 3.0 TDI in early November and later broadened it to around 85,000 vehicles from the 2009-2016 model years, including diesel examples of the Cayenne, Volkswagen Touareg, Audi A6, A7, A8, Q5, and Q7. Audi later admitted the engine contained previously undisclosed auxiliary emission control devices. CARB gave the automaker 45 days to come up with a recall proposal to fix the 15,000 affected models in the state. Related Video:

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
Take a look and let us know what you think in Comments.

Audi says fixing diesel emission problem is simple

Audi reportedly has a simple repair nearly ready to fix the emissions problem on 85,000 vehicles with the 3.0-liter TDI V6 in the US. "Swift, straightforward and customer-friendly solutions are in discussion," company exec Rupert Stadler told workers in Germany, according to Reuters. In late November, Audi announced that the 3.0 TDI had three previously undisclosed auxiliary emission control devices, including one that was potentially considered a defeat device under US law. At the time, the German automaker claimed it could repair the problem with just a software update. Stadler's statement indicates that just such a simple fix might be on the way. Even before Audi's disclosure of the emission control devices, the Environmental Protection Agency issued a notice of violation against the 3.0-liter TDI for allegedly having software to defeat emissions tests, and the agency later expanded the scope to any vehicle with the engine from 2009 through 2016. The affected models include the Audi A6, A7, A8, Q5, Q7, Volkswagen Touareg, and Porsche Cayenne. New diesel versions of these vehicles have a stop-sale. Audi offered owners of affected vehicles the same $1,000 Goodwill Package that parent company VW offered to its affected diesel owners. The money is split up into a $500 gift card and $500 to spend at the Audi dealer. The package also comes with extended roadside assistance. Audi needs to find a solution quickly because it's under a 45-day deadline from the California Air Resources Board to submit a recall plan for the 15,000 vehicles with the 3.0 TDI in the state. The automaker also must include a report on any effects to fuel economy and performance from the proposed repair. Related Video:
