Porsche plans to expand its Panamera line-up to include three new powerplants – a Volkswagen-sourced V6, a diesel and some manner of hybrid – but in addition to offering new engines, the automaker may offer a harder, more performance-oriented model to slot in above the Turbo.

Similar to the strategy Porsche employed with the Cayenne, this new model – which could be dubbed the Turbo S or GTS – would nix the Turbo model's standard air suspension and instead fit a set of performance-tuned springs and shocks to maximize grip and on-track prowess.

As for future powertrains, a senior Porsche executive told Autocar that VAG's V6 and V8 diesels could be fitted to future Panameras, and we wouldn't be surprised to find the new Audi S4's supercharged, petrol-powered 3.0-liter V6 in Porsche's first production sedan in the coming years.
