Porsche is lining up a new supercar, closely linked to the hi-tech 918 Spyder hybrid, to mark its return to the Detroit motor show in January.

Sources in Germany say the centrepiece of the Stuttgart firm’s appearance at Detroit will be a “spectacular new concept that points towards a future roadgoing model”. It’s thought the car will share some key components, including elements of its platform, with the 918 Spyder, the star of the Geneva show earlier this year.

No details of the car have been released, but it’s possible that Porsche is planning to capitalise on high demand for the 918 by fast-tracking a more conventionally powered ‘halo’ model to market.

Porsche has been absent from the Detroit show since 2006. But it is returning this year as part of the ever-expanding Volkswagen Group line-up.
