Some Porsche Models Found to Have Emissions Cheating Software

Well this is not very surprising considering the fact that Porsche is a subsidiary of Volkswagen. Given the benefits of scaling effects it's normal that VW tries to share as much technology as possible between its different car brands (e.g the chassis of Audi's cars are almost identical to VW's own models [2]), and software modules for fuel injection seem like a very good candidate for a shared technology platform as most of the underlying hardware comes from the same manufacturer (e.g. Bosch).

I wouldn't be surprised if other brands would be affected too, e.g. Seat and Skoda. That they also tuned the engines of Lamborghini, Bugatti or Bentley seems less likely since those cars are not renowned for their fuel-efficiency to begin with, but who knows.

That said, many people in Germany (including me) are very angry about this whole affair since this one act of fraud (and yes it was fraud) will probably do great damage to the reputation of our whole industry.
