A set of slides that included Porsche's upcoming projects have reportedly leaked from an internal dealer meeting that took place in Atlanta, Georgia.

There's no confirmation of their authenticity, but the stuff revealed in the slides look and sound reasonable.

The first piece of information is in regards to the new GTS versions of the Porsche Cayman coupe and Boxster roadster models, with features said to include a 15-horsepower bump for a slightly faster 0-60mph (96km/h) sprint time, Sport Design front and rear fascias, 20-inch Carrera S wheels, upgraded steering wheel, and leather interior. It's also mentioned in the slide that the two models will break cover at the Beijing Auto Show in China next April.

Then there's the all-new Porsche 911 Targa, which alleges that the Targa will have a "Fully automatic roof system to satisfy customer demands for comfort". We're not sure how this will work given that the new Targa will feature a similar center pieces as the classic version of the car. The snapshot of the slide says that it will be available in both Carrera 4 and Carrera 4S trims.

The final car featured in the leak is the upcoming Macan, which is a rendering from a German magazine. The presentation says the Cayenne's little brother will be unveiled at the 2013 LA Auto Show, which isn't really news, but it does reveal details on the prices and engines.

The U.S. range will kick off with the Macan S powered by a 3.0-liter V6 and priced from around $52,000, and the Macan Turbo with a force-fed 3.6-liter V6 starting at $75,000.

But let us remind you that we're not sure if the information above is true, and sourced from an official Porsche meeting.
