The Porsche Panamera is a mid/full-sized luxury car (E-segment/F-segment in Europe) manufactured and marketed by German automobile manufacturer Porsche across two generations using a front-engine, rear or all-wheel drive configuration. Porsche debuted the production first generation Panamera at the 13th Auto Shanghai International Automobile Show in April 2009, launching hybrid and diesel versions in 2011. In April 2013, the company introduced a facelifted model, again at the Shanghai Auto Show, followed by the US introduction of a plug-in hybrid version, the Panamera S E-Hybrid, in November 2013. Porsche introduced the second generation Panamera in 2016. The Panamera name, as with the Carrera name, derives from the Carrera Panamericana race.

Being derived from the V8 engine of the Panamera S and Panamera 4S, the V6 retains the V8's technologies like Direct Fuel Injection, infinitely variable intake camshaft adjustment with variable valve lift (VarioCam Plus), an on-demand oil pump, water cooling with thermal management, a variable intake manifold, as well as integrated dry sump lubrication with two-stage extraction of oil, and an Auto Start-Stop function (only with the PDK transmission).
