By now, we pretty much know exactly what the new 992 Porsche 991 will look like, thanks to revealing spyshots of near-undisguised prototypes. However, our spy photographers have now captured the new car and the current 991 model line astern, giving us a better look at the changes between the generations.

At the front, the changes are subtle, with the most prominent being the longer bonnet that now ends at a new horizontal bumper shutline, giving it a more classic 911 look. The front air intakes have also been mildly reprofiled, and there are also new flush-fitting door handles and revised door mirrors.

More apparent are the tweaks at the rear of the car, including new full-width tail lights (seemingly on all models now, not just the all-wheel drive ones), a vertical centre brake light, a larger active rear spoiler and a redesigned diffuser that now carries the rear number plate recess.

Past spyshots gave us a look at an interior that looked similar to that in the new Panamera and Cayenne, with a horizontal dashboard, a tall centre console, a large centre display and (unlike the Panamera, thankfully) manual air vents. There will also be digital instruments for the first time, retaining the trademark five-dial design and flanking an analogue rev counter.

As for the engine, expect the cooking Carrera models to retain the 3.0 litre turbocharged flat-six from the facelifted 991, likely reengineered for improved power, fuel economy and emissions. The seven-speed manual and PDK dual-clutch transmissions should also soldier on.
