The current-generation Porsche 911 was unveiled in 2011, so the timing is about right for us to be seeing developmental versions of a facelifted model running around on public roads and on the Nurburgring.
Compared to earlier photos, this vehicle almost completely free of disguise.
Up front, there's a revised bumper with reshaped air intakes, a revised front splitter and thinner LED daytime running lights
At the rear, this vehicle features twin central exhausts, a different grille above the engine bay and a few extra air vents. These extra vents may be found on all variants of the revised car, as the 911 will soon adopt turbocharging across the entire non-GT range.
The 911 facelift was last spotted at the beginning of March. That vehicle, which was seen battling the white scourge of winter, had a fixed rear wing and a more aggressive aero skit.
Unlike that car, this prototype is a milder variant and is equipped with a pop-up rear spoiler, which was in the up position when it was spotted on the Ring and down when photographed in the town of Nurburg.
Parked and unattended, March's high-power version of 911 gave us all a clear look at the updated car's interior, which will feature a larger touchscreen and a new steering wheel.
It's expected that the revised 911 range will be unveiled at the Frankfurt auto show in September. The updated car will then head into showrooms around the world during 2016.
