It appears as though the Panamera sedan will actually look something like a four-door hatchback. Cut lines clearly show a rear window that starts at the top of the C-pillar and extends all the way down to just above the license plate. It’s an odd design cue to say the least, but it should keep the Panamera from getting lumped in with the rest of Germany’s luxury sedans.
Other notable design elements include a side window that extends rearward all the way to the middle of the rear wheel and taillights that wrap around to the side of the rear quarter panel. Up front, it appears as though there might be a set of quarter-panel vents just after the front wheels along with the usual air intakes in the airdam to feed the V8 engine under the hood.
