Sources have managed to snap the first shots of the new (and presumably last-generation) Porsche Panamera sans most of the camouflage near Porsche's development center in Weissach, Germany. The second-generation Panamera arrived in 2017, so a replacement seems imminent based on the timeline of the original model, which lasted six years.
The final product seems to borrow styling elements from the Porsche Taycan. As for engines, there's no word yet on what will power the next-generation Panamera, but previous spy shots hinted at a hybrid drivetrain based on the presence of two fuel doors. However, all angles in this latest spy shot batch only include the passenger side, so it's unclear if the prototype had a charge port on the driver side.
