Porsche has already confirmed that it will offer a hybrid version of the Panamera after the gasoline Panameras make their market debut later this year (no official date on when the hybrid Panamera will arrive in dealerships). According to AutoCar, Porsche is also planning a diesel version of the new Panamera and is looking to use existing Volkswagen diesel engines.
Porsche is also said to be working on an even faster Panamera that will sit above the Turbo model. It will use the same strategy as the Cayenne GTS and will do away with the Panamera Turbo’s standard air suspension and replacing it with steel springs.
