The facelifted 992-generation Porsche 911 GTS has been spied testing once again as the automaker gears up for a market launch before the end of this year.

This particular prototype was snapped during the final days of its winter testing regime and our spy photographers speculate that the center-lock wheels are a telltale that this is indeed a GTS. While it may not look considerably different than the current model, there are still plenty of changes you’ll notice if you put on your glasses.

Many of the changes have been made on the front end. The headlights are new and while the overall shape has gone unchanged, Porsche has tweaked the shape of the four small LED DRLs within them. Additionally, the front air intakes are much larger than the outgoing 911 GTS, allowing Porsche to reduce the size of the small central grille area. The new intakes also stand out because they now have three horizontal slats rather than one and instead of the radiators being open and easily visible, they are hidden by a second set of slats, this time running vertically and with the ability to open and close.

Porsche has also made some changes to the 911 GTS’s rear end. For example, the LED taillights and light bar have been tweaked while the shape of the bumper has also been altered. In addition, the two exhausts have been pushed closer together and now sit nearer the center of the bumper. Alterations have also been made to the intakes on the engine cover.

Limited details are known about the powertrain of the new 911 GTS. In October last year, our spy photographers spotted another GTS prototype testing at the Nurburgring but that model was particularly intriguing as it had yellow stickers across the exterior, suggesting it was equipped with a hybrid powertrain. This led to speculation that the 911 GTS could be sold exclusively as a hybrid. However, the lack of yellow stickers on this latest prototype indicates that won’t be the case.
