Ferrari are confident the engine failure that cost Felipe Massa a win at the Hungarian GP was a "one-off."

Massa was in course for his first victory in three races when his Ferrari engine blew just three laps from the end in Budapest.

Ferrari, though, are confident that Massa nor his team-mate Kimi Raikkonen will suffer the same fate again.

"We are confident that the failure we suffered in Budapest was a one-off," a Ferrari spokesman told ITV.
