As part of its 70th anniversary, Porsche has taken the wraps off its new 911 Speedster Concept, which the brand describes as “a road-ready study of an exciting open-top sports car”.

Porsche says the drive technology under the concept’s two-tone shell is derived from its current GT models (the chassis essentially comes from the 911 GT3), while the “broad body” of the concept car has been borrowed from the 911 Carrera 4 Cabriolet. However, the wings, bonnet and rear cover are made of lightweight carbon-fibre composite material.

The Stuttgart-based automaker says the concept “offers a glimpse of a potential series-production version, although this model may not be presented until 2019”, adding that a decision on whether to move ahead will be made in “the coming months”.

Porsche says the exhaust system features titanium tailpipes while the flat-six (mated to a six-speed manual transmission) delivers more than 370 kW and spins to speeds of up to 9 000 r/min.

The 911 Speedster Concept features a shorter window frame with a more inclined screen and correspondingly shortened side windows. A rear cover fashioned from carbon-fibre connects behind the front seats, covering a roll-over protection structure and featuring a “double bubble”.

The show car furthermore features a lightweight tonneau cover instead of a convertible top, which Porsche says “protects the car interior from rain when parked”, and is attached using eight Tenax fasteners.

Inside, you won’t find navigation, radio or air conditioning systems, which have all been sacrificed at the altar of weight saving. The bucket seats, meanwhile, are made of carbon and covered in light brown Aniline leather.
