First posted on BMW's official Korean Instagram account, a darkened image shows a disguised 5 Series wearing the same redesigned front-end look as previously spotted prototypes.
Captioned 'the 5 and the 6', the image along with further social media posts reveals the 6 Series Gran Turismo will also be similarly updated and shown at the same time.
Previous spy shots of test mules preview the updated model in both saloon and Touring variants. Like the saloon, the estate appears to gain only subtle tweaks to the front and rear, but we can see that hybrid versions will be told apart by a bespoke front bumper design, with a horizontal vane spanning the width of the lower air intake.
Previous reports that BMW would significantly increase the size of the executive car's trademark kidney grille appear to be incorrect, as it looks to have grown more subtly than it did on the facelifted 7 Series.
The move is part of a broader strategy at BMW that aims to give each model its own individual appearance, with the latest 3 Series sporting a different front-end look.
Further design changes include redesigned headlights and a more heavily structured front bumper that incorporates newly designed air vents, including vertical air curtain ducts at the outer edges.
Changes at the rear are likely to be less significant, although the plastic wrap adorning the spied prototypes hints at styling revisions to the tail-lights, rear bumper, tailpipes and area around the numberplate.
Inside, the 5 Series is expected to receive new digital instrument graphics as well as a revised central display housing the infotainment functions.
Today’s 5 Series will get BMW’s latest iDrive 7.0 operating system as part of a running change from this month onwards, suggesting the 2020 model will carry this on until the introduction of an iDrive 7.5 system in the eighth-generation 5 Series model due in 2023.
The prototype displayed here is propelled by a plug-in hybrid powertrain, shown by the mandatory identification on its front doors as well as the flap for the charging port integrated into the front-left wing.
