First, let's go over the basics. Round headlights, bulging front fenders, wide hips, and that distinctive roof and window line. All of these will remain on the 911 until the end of time, with some slight modifications to the formula every so often. On the new model, the headlights are tilted back a hair and sit slightly flusher with the fender. This has the effect of lessening the fender bulge. Also, the headlights no longer meet the bumper, and when combined with the longer hood, give the front end a shape reminiscent of the 993 generation.
Around to the side, the window looks almost identical to the current model – but the current one looks almost identical to the generation before that. The door handles have been redesigned and now sit flush with the door itself. Aside from that, the profile has changed very little. Stuttgart may burn if Porsche designers tried to stray too far from this design.
Like the front, there are a number of small but notable changes to the rear of the car. The movable rear spoiler extends to the edges of the bodywork rather than ending at the edge of the hood. The first model in these photos appears to be a 911 Carrera 4S given the bumper width light bar and the vents in the bumper's corners. Unlike the 991.2 generation, it looks like Porsche is considering switching back to quad exhaust tips for the S models. The second car has front and rear bumpers that resemble the 911 Turbo, but it lacks the side air intakes that have been present since the 993 version.
No word on how much of the new engine line will carry over. For 2017, Porsche switched to turbocharged engines for every model except the 911 GT3. The move was met with some initial criticism, but so has every change the automaker has ever introduced. This model looks fairly far along in development, but don't expect to see a full reveal anytime soon. We're sure Porsche wouldn't want to tank sales of the recently introduced 991.2.
