Just hours after Porsche posted its latest teaser video of the next-gen Panamera, three photos of the luxury sedan leaked on Instagram. The photos do well to highlight the changes made to the front and rear ends, and show off the Panamera's sleeker body.

At the front, we see the revised fascia gets a new grille design, headlights, and foglights, but the biggest changes happen in the rear. Gone is the hunchback look of the outgoing sedan. In its place is a much sleeker, more 911-like design. The proportions make it look much more like the four-door coupe it's supposed and less like an overgrown hatchback. The taillights feature a new design, and run the length of the rear. The lower bumper now features reflector strips just above the dual exhaust pipes on either side.

The next-gen Panamera was set to be revealed next week in Germany, and Porsche has released teasers leading up to the event. The Nürburgring serves as the location for the most recent teaser video, where a team of professional drivers suits up and uncovers the new Panamera. We see the luxury sedan from above, but thanks to the lighting, we can't make anything out. Now that the car has been leaked, we don't need to. The track lights turn green and we're left with a slight engine growl, along with the date and time to watch the official unveiling of the Porsche Panamera.

Earlier this month, Porsche shared a teaser photo of the rear lights and a video that highlighted the "madness" of the brand. Before the first video was released, we caught spy shots of the next-gen Porsche Panamera nearly free of any camouflage, looking production-ready. The new four-door will ride on VW Group's MSB platform, and we expect it to offer an updated version of the current model's 3.0-liter twin-turbo V-6, a 4.0-liter twin-turbo V-8, and at least one hybrid variant.

Check out the latest teaser video below, along with the leaked photos, and stay tuned for the official reveal on June 28.
