The Porsche 911 Speedster concept car is expected to receive the green-light for production within weeks. The car is on display at the Goodwood motor show, the central theme of which is Porsche’s 70th anniversary.
Although the Stuttgart company has stopped short of confirming the 911 Speedster will be built, it describes the concept as a “potential series-production version”. Prototypes have already been spotted testing in Germany.
Autocar has learned that a final decision is now imminent, with a positive one expected. It should then be on sale within the year, in a production run of less than 2000 units but greater than the 356 units built of the previous 997-generation Speedster.
The Speedster, which would be a swansong for the current 991-generation 911, is the combined work of Porsche’s GT division and its Exclusive one, mixing its finest engineering department with the one responsible for bespoke designs.
As previously reported by Autocar, the open-top concept shares its chassis with the 911 GT3 and employs a six-cylinder engine delivering “more than 500hp” and revving to 9000rpm. This is expected to reflect the production 911 Speedster, which will use the GT3’s naturally aspirated 4.0-litre flat six. In the GT3, it delivers 493bhp and 339lb ft.
The concept uses a six-speed manual transmission. If the production version follows the example of the GT3, it will be offered with either a six-speed manual or seven-speed PDK transmission.
The 911 Speedster will have a lightweight tonneau cover rather than a convertible top, while other weight-reduction measures include the removal of the sat-nav, audio and air-con systems. The bucket seats are made of carbonfibre.
The concept car’s body is based on the 911 Carrera 4 Cabriolet but with wings, front bonnet and rear cover made from lightweight carbonfibre composite.
A rear cover, also made of carbonfibre, connects behind the front seats, covering a roll-over structure and featuring a ‘double bubble’ — an iconic design element of 911 Speedster models since 1988.
The concept features details that celebrate Porsche’s early racing days, such as the 1950s-style central fuel tank cap positioned in the middle of bonnet and the classic Talbot shape of the mirrors, and it’s part of the 70th anniversary of the firm’s sports cars.
The shape of the model, including the very low fly line, takes influence from the original 356 1500 Speedster that has inspired 911 Speedsters for the 930, 964 and 997 generations.
The last Speedster cost about £50,000 more than the GT3 of the time, suggesting the new model could sell for in excess of £155,000.
