Porsche seems to be having a hard time keeping the 992-generation 991 under wraps, as not one but two prototypes have been caught almost completely undisguised following online leaks and other recent sightings. This time, a red example has joined the blue model that was spotted last month. On closer inspection, some sections have been covered up, but we still get a clear view of the production model potentially months before the official reveal.

Of the two, the blue model is more elegant and features the sport exhaust suggesting we could be looking at the new Carrera S, while the red model sports a beefier quad exhaust setup. Overall, the design changes are evolutionary rather than revolutionary, just as you would expect from a new 911. There are some key changes under the skin, however.

The 992-generation Porsche 911 rides on an updated MMB platform, which is stronger and stiffer and can incorporate hybrid powertrains. Because of this, the new 911 is also slightly longer and looks more muscular with wider wheel arches. At the front are new LED headlights, which have been covered up in tape, along with a redesigned front bumper with large intakes at each corner. Slim taillights are connected by a full-width light bar that remind us of the Taycan.

In terms of powertrains, the base 992 Carrera is expected to produce around 400 hp a flat-six engine, while the output of the Carrera S could increase to 450 hp and the range-topping Turbo S will allegedly pack 620 hp. A hybrid version will also join the range for the first time in the model's history, which is expected to be the most powerful 911 ever made packing 700 hp. The 2019 Porsche 911 is expected to break cover at the Paris Motor Show in October, so we shouldn't have long to wait to find out all the details.
