The darkened shots, showing the model in what appears to be a pit garage, reveal that the GT3 will retain the distinctive, race-inspired rear wing design seen recently on later-stage prototypes. The preview release also confirms the unveiling will take place on 16 February at 2pm UK time.
Although we've not had a view of the car's front end, the extensive number of prototypes spotted around Germany with ever-reducing levels of disguise through last year revealed a number of key GT3 details.
Alongside the prominent wing, there is a sizeable rear diffuser, front splitter and centre-locking wheels, which are now a hallmark of the model. A pair of new air intake slits can be seen in the bonnet, while the lower grille is significantly wider than any current 992-generation car's. There's also a centre-exit dual tailpipe.
Those sightings followed an earlier video of the track-focused model being tested at speed on the Nürburgring, revealing its flat-six soundtrack.
The collection of clips of a prototype undergoing track development confirms what we knew already: that the next GT3 will retain the naturally aspirated boxer engine loved by enthusiasts.
Although it's hard to be sure, it sounds like the 992-generation GT3 hasn't lost any of the previous model's volume and tone, despite the addition of a petrol particulate filter and other emissions-reducing tech.
Also seen at the end of the video is a GT3 minus the trademark wing, suggesting the sought-after Touring model will make a return.
Further details have yet to be revealed, but we do know the 911 Speedster’s heavily revised 4.0-litre flat-six engine will be carried over to future GT models as Porsche’s GT division persists with naturally aspirated engines.
GT boss Andreas Preuninger said: “We’ve invested in the future with this engine. I can’t comment on future projects but we would be stupid not to re-use this engine somewhere.
“Our philosophy in GT cars is to stay naturally aspirated. We want to keep that engine for the future and that’s why we’ve made such a tremendous effort to get the engine right without taking emotion and performance away.”
