Ferrari have managed to get to the bottom of Fernando Alonso's DRS failure in Bahrain, saying it was a "first of its kind".
The Spaniard's challenge for the race win was over as early as the eighth lap as he was forced to make two unscheduled pitstops after his rear wing got jammed and failed to close.
Although he was unable to use DRS for the rest of the race, Alonso still managed to finish eighth as he proved he doesn't need the overtaking aid to pass drivers on the track.
Ferrari, though, is determined to make sure that they don't suffer a similar problem in future as they believe Alonso would have challenged Sebastian Vettel for the win.
"Analysis revealed that the problem was caused by the breakage of a mechanical component within the system," a statement on the website read. "It's the first problem of its kind on this system seen in the three years during which it has been used.
"The failure is not something that causes concern for the long term, however, paying great attention to reliability must always remain at the highest level. It has often been the case that it takes only a small problem to prevent the car's full potential from being exploited.
"The disappointment at what happened is even greater when one looks at the usual analysis of performance over the race weekend, which shows that Alonso could definitely have been fighting with Sebastian Vettel for the win."
Alonso's team-mate Felipe Massa had an even worse day as he finished in 15th place after suffering two punctures and the result left Ferrari 32 points behind Red Bull in the Constructors' Championship.
Team principal Stefano Domenicali was left frustrated and he admits they can't afford to have too many off weekends.
"We must work with renewed attention on this front," the Italian said. "We must also continue to develop the car and increase our understanding of the tyres, which is more crucial than ever this year.
"In these first four races of the season, we have not managed, for various reasons, to bring home the points that were within our grasp. That's why the gap to the top in both classifications seems quite large, but we must not be discouraged by this, quite the contrary, because we have seen so often, both in our favour and against, how things can change in a hurry.
"We believe in our ability to be in the fight for the titles right to the end and this time, we have been in that fight since the start, which has not been the case for a while. At the same time, we must be aware that in order to achieve our objectives, we have to be perfect in every area."
