The first photos of Porsche’s new GT3 and GT4 machinery have been revealed, following a multi-day test for the German manufacturer at Monza.

Both the soon-to-be-launched 2019-spec Porsche 911 GT3 R and new Cayman GT4 Clubsport MR appear to have been testing at the Italian circuit, alongside Porsche’s current-generation 911 RSR GTE car and another unidentified car, which could be the 911 GT2 RS.

The images, courtesy of monzamotorsport.com, shows noticeable aero changes to the GT3 model, including a re-profiled nose, increased cooling ducts on the side and a larger rear diffuser.

Porsche’s second-generation GT4 car, meanwhile, is understood to feature a 4.0-liter flat-six engine compared to its current 3.8-liter powerplant.

Sportscar365 believes that the new GT3 car could be formally launched next month ahead of its race debut later this year, likely in VLN competition. A similar timeline for the GT4 model could also be possible, as part of Porsche’s all-new customer GT lineup offering for 2019.
