Hands Up Don't Sell!: Porsche issues stop-sale order for Cayenne Diesel

Porsche issued a stop-sale order for the Cayenne Diesel after the U.S. Environmental Protection Agency (EPA) levied additional accusations of emissions-test cheating against Porsche parent Volkswagen Group.

Sales of 2014 through 2016 Cayenne Diesel SUVs are being halted until further notice, in light of the “unexpected” EPA finding that the vehicles were equipped with software that allowed them to cheat on emissions tests, a terse Porsche statement disclosed. Dealers will not be able to sell any new or used Cayenne diesels they might have in stock until Porsche ends the stop-sale order.

Earlier this week, the EPA said that Volkswagen Group models using a 3.0-liter V6 diesel engine were equipped with the same “defeat device” software previously found on 482,000 2009 to 2015 models in the U.S. equipped with a different, four-cylinder powertrain. Although Porsche is stopping sales of 2014-2016 Cayenne Diesels, the EPA only cited the 2015 model, along with the 2014 Volkswagen Touareg TDI, as well as the 2016 Audi A6, A7, A8, and Q5 TDI.

As with models implicated in emissions cheating back in September, the EPA said these Audi, Porsche, and Volkswagen models were equipped with software that allowed onboard systems to detect an emissions test, and adjust vehicle parameters. On the road, emissions controls are bypassed, meaning these vehicles could be emitting up to nine times the legal amount of pollutants, the EPA said.

Porsche initially said it was “surprised” by the finding, and claimed that it believed the Cayenne Diesel was “fully compliant” with emissions regulations. The carmaker notes that all affected vehicles are still safe to drive, and that owners can continue doing just that. Porsche did not discuss a timeline for a recall, or any potential fixes.

While it deals with accusations of additional cheating, Volkswagen also admitted this week that it understated the levels of carbon emissions in certifications for 800,000 cars worldwide. It said it uncovered “unexplained inconsistencies” in reporting of emissions levels during an internal investigation relating to the ongoing diesel scandal. The company estimates this latest issue could cost it $2.2 billion.

The affected cars are “mostly diesel” models from Volkswagen and other brands like Audi, Seat, and Skoda, implying that some gasoline models may be affected as well. VW said a recall will not be necessary in this case, which is not related to the “defeat device” software.

Rivian R2 vs R1S: How will Rivian’s cheaper SUV compare?
The front three-quarter view of a 2022 Rivian against a rocky backdrop.

Rivian has finally unveiled the R2, its long-awaited attempt at a more affordable electric SUV. The new vehicle may not be available just yet, but fans of Rivian's design aesthetics and feature set are already looking forward to being able to order the new car. The R2 is targeted at being a more affordable take on the electric SUV and will sit alongside the flagship-tier R1S.

Let's get this out of the way right now: The R1S is most likely going to be a better vehicle than the R2. Rivian isn't replacing the R1S with the R2 — it's releasing the R2 as a more affordable alternative, and there will be some compromises when buying the R2 over the R1S.
