The official launch of a new Norfolk-made bio-diesel sports car has been cancelled at the 11th hour.

Trident Performance Vehicles Ltd, of Beeston, near Dereham, was due to be unveiling its 6.6lt V8 car, the Iceni, at The Forum, in Norwich, tomorrow morning prior to a 1,000 mile challenge on one tank of bio-diesel fuel.

But the journey from Norfolk to Monaco by Trident sales director Kelly Bevan and motoring journalist Suzannah Sorrell was postponed today following a “last minute change of plan”.

The Norfolk company said the Iceni was still going to be displayed at this week's Top Marques Show, however, the car was now being transported to Monaco on the back of a lorry.

A spokeswoman added that the 1,000 green mile challenge was being rescheduled for a later date.

“We are really sorry for the inconvenience caused, but it was out of our control.”

“We have been let down by a supplier of a gear box, however, the 1,000 mile run is going to happen and we hope to do it for the Monaco F1 Grand Prix next month,” she said.

A spokeswoman from Breckland Council, which supported the Trident scheme with a £3,000 REV project grant, added that officials at the Top Marques Show - the most prestigious luxury and super car show in Europe - had requested the Norfolk car to arrive a day earlier than scheduled.
