We heard the first details on the possibility of a new 550 shortly after Volkswagen unveiled the Volkswagen Bluesport concept. Back then, the 550 was believed to be one of the three production models rumored to be based on the Bluesport: one from Audi->ke14, one from Volkswagen->ke94 would have joined Porsche. Unfortunately, that all ended when VW announced that the Bluesport would bot be produced.

Now, new details suggest that the 550 will instead be built as a new Speedster version of the new-generation 911. Reports suggest that it will be built as a tribute to the classic 550 Spyder built from 1953 to 1957. The new model is rumored to be unveiled sometime in 2015, and will be limited to only 550 units.

According to AutoBild, the new 550 will feature hidden door handles -- just like the classic 550 -- a chopped-down windshield and a fabric top that will reside under a rear cover made from carbon fiber. This makes it possible for the fabric top to be used only when it is absolutely necessary.

Porsche 911 Speedster

Porsche unveiled its latest 911 Speedster model at the 2010 Paris Motor Show, when it was based on the 997-generation Porsche 911. The model was distinguished by an aerodynamic body kit package, tinted headlights, black accents, a soft-top cover, a special front apron, specific side skirts, a distinct rear apron and a choice of two paint options: Carrera White and Pure Blue.

Under the hood, it had a 3.8-liter, flat-six engine that produced 408 horsepower and was mated to a seven-speed PDK transmission.

Despite being a very expensive car -- it was priced at about €200k -- the car was sold out before being put on sale.
