Virgin F1's plans to introduce a car with a fuel tank big enough to finish races in time for the next grand prix may be scuppered by the current volcanic ash air crisis.
The team was forced to seek FIA clearance to introduce a new chassis earlier this year, after discovering that it had designed the car with a tank that was too small to finish races.
However, the Virgin race cars and personnel are currently stranded in Shaghai, meaning work has been delayed.
The Spanish Grand Prix is on 2 May.
