The upcoming new four-door Porsche, spied wearing only minimal camouflage, appears to have a more elegant and sloping roofline than the existing model. Other details like the lights, mirrors and grille openings look fairly consistent with what we've been seeing on Porsche's other models as they've trickled out.
Based on the new MSB platform, the new Panamera is set to share its underpinnings with the next Bentley Continental and possibly an Audi variant as well – though the prospect of a Lamborghini version to follow the Estoque concept seems to be off the table. The new platform will, however, make the new Panamera lighter than the current model. A new range of V6 and V8 engines are expected to provide motivation, driving the rear wheels or all four, along with the available e-hybrid system.
Porsche's first four-door sedan was introduced in 2009 and underwent a facelift in 2013, so the all-new second-generation model should arrive sometime later this year or next as a 2017 model. This new model could provide the impetus for Porsche to put the Sport Turismo shooting brake version into production as well, and maybe – just maybe – a two-door coupe and possible convertible versions to follow in the footsteps of the 928.
