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:

Which is quicker in the standing mile, a Subaru WRX STI or a Porsche Cayman?

The 2015 Subaru WRX STI and 2014 Porsche Cayman are both saddled with unfair reputations. The STI with its huge wing and gold wheels has the title of the ultimate boy-racer. On the other hand, Porsche brand snobs look down on he base Cayman as just a wannabe 911. In reality, they are both pretty fantastic performance cars. But what would happen if the two of them lined up at a stoplight, and maybe the guy in the suit in the Cayman started throwing some revs at the young man in the STI? Automobile decided to find out in a recent video pitting the two stereotyped hot rods against each other in a standing-mile drag race.
In terms of raw numbers, they are surprisingly close. Both use flat engines and six-speed manual transmissions here, but the Subaru has more power and torque. However, the Porsche makes up for it with 300 pounds less weight. Neither should have a problem with traction either thanks to the STI's sophisticated all-wheel-drive setup, and the Cayman's mid-engine, rear-wheel-drive layout.
The comparable specs certainly show themselves in the real world for the race. We're not going to give away the winner here because it's too exciting, but let's just say the finish is very, very close. Scroll down to watch both of them shrug off their stereotypes and show off their real performance.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.
