Design work for both projects is said to be at an advanced stage, with Alpine boss Carlos Tavares and Caterham owner Tony Fernandes said to have approved designs that will push the £50,000 Porsche Boxster rivals in different directions.
"This is not a project that will create two cars that look the same, like the Toyota GT86 and Subaru BRZ," said van den Acker. "What we plan to create is two cars that will look completely different. People will not recognise them when they are parked together."
Renault marketing boss Steve Norman has previously told Autocar that the Alpine will have DNA that is "French and not German".
“It must be light and look different, and have a touch of French dash,” said Norman. “It’s not a car for dandies, though. We know who the buyer is: he’s either French or a Francophile. And the car has technical innovation as part of its DNA.”
The Alpine A110 will also play a key role in shaping the reborn brand's new car according to van den Acker. "It is the car that sparked the dream of rebuilding the brand," he said. "To not acknowledge that in my design would be to disappoint the dreams of these enthusiasts."
