Apollo Automobil has teased an image of an all-new supercar it plans to offer alongside the production version of the Arrow it unveiled at last year's Geneva motor show.
Other than its 'IE' name, and the single image showing a huge rear wing, little has been released on the new concept.
Rumours doing the rounds in Europe suggest the IE could be the FIA-approved racing version of Apollo's road car which has been developed under the 'Project Titan' moniker.
If so, it is likely to come powered by an all-new naturally-aspirated 750kW/1000Nm V12 which will be shared with the Arrow.
Originally, the reborn Gumpert supercar brand said it would build cars in co-operation with American-Italian specialist Scuderia Cameron Glickenhaus, but now reports suggest that deal has sunk.
Confusingly, Apollo says in the future it will continue to work with Turin-based Manifattura Automobili Torino (MAT) - the same company which assisted in development and engineering of the SCG003C revealed at the Geneva show last year.
Both a road-going Arrow and Apollo race car were planned to star at last weekend's Goodwood Festival of Speed but failed to arrive.
