One by one, all models of Porsche’s extended 911 family are going under the knife for the 991-generation’s first facelift, with our spies now capturing the 911 Turbo S.

The 991 came forth to the public three years ago at the 2011 Frankfurt Motor Show and the updated variants are expected to be gradually introduced within the next 18 months, possibly under the 992 internal codename.

Most cosmetic changes including the head- (not used on this tester) and tail-lamp revisions, newly designed door handles, and interior improvements should be common across the board, with models like the 911 Turbo S pictured here to get some unique updates like the restyled bumpers and engine cover.

While we expect Porsche to implement changes to the chassis, we’re still uncertain if and how the Germans will update the 911 Turbo’s 513hp (520PS) or in the Turbo S’ case, 552hp (560PS), inline-six boxer engine.
