Renault has called off its scheduled test for next week at Barcelona.

Renault has called off its scheduled test for next week at Barcelona.

The German specialist magazine Auto Motor und Sport said the change of plans is in response to the troubled track debut of the French team's 2009 car, the R29.

The Enstone-built single seater, to be raced this season by Fernando Alonso and Nelson Piquet, has been regularly slow and also unreliable since it was launched in Portugal last month.

Instead of going testing next week, factory-based engineers will work on the car's shortcomings, Auto Motor und Sport said, before returning for two more tests in the run to March's Australian grand prix.

On the bright side, Nelson Piquet tried Renault's KERS system at the Kemble airfield in England recently and "everything worked perfectly", the Brazilian is quoted as saying.
