Suit alleges multiple issues cause higher emissions, consumption
Covers numerous 2009-2016 models
A class-action lawsuit has been filed in British Columbia aimed at certain Porsche models, claiming that the vehicles emitted more CO2 and used more fuel than was advertised and claimed. The filing calls the changes deceptive and illegal and is looking for damages as a result.
The suit filed in BC Supreme Court is Trevor Stone, v. Dr. ING. H.C. F. Porsche AG, et al., (via Car Complaints), and says that it concerns 2009-2016 Porsche Boxster and Boxster S models as well as Cayman and Cayman S models, the 2012-2016 911 Carrera and Carrera S and the 2010-2013 Porsche Panamera S as well as certain Cayenne models.
There are three main claims: that the defendants “physically altered the hardware (the gears connecting the driveshaft and rear axle) and manipulated the software in Class Vehicles used for regulatory testing so that the testing vehicles would emit fewer pollutants and be more fuel-efficient than the versions the defendants sold or leased to consumers, that they “installed secret software in the electronic control unit (“ECU”) of Class Vehicles, causing them to perform differently in testing than on the road, and that “the Sport Plus mode exceeded legal limits of certain pollutants, making vehicles with this feature illegal to import or sell in Canada.”
The first alleges that Porsche used a more fuel-efficient gear ratio in the differential for testing than they did for actual cars sold, and bases its claims on testing performed in the US. The second mentions a software “cheat” mode similar to what had occurred with the VW Group diesel emissions scandal, and the third was based on a Porsche internal investigation and recent stop-sale of used vehicles that said that Sport Plus mode in certain vehicles could exceed allowable emissions limits. The suit claims Porsche was aware of the issues as soon as November of 2015.
The case was filed last month, and the allegations have not been proven in court.
