Red Bull departed from Monza baffled, after winner Sebastian Vettel and and third placed Mark Webber nursed gearbox problems throughout the race weekend.
“We already had problems on Friday,” world championship leader Vettel is quoted by Germany’s Auto Motor und Sport.
Before the race, the team had to open the gearbox and replace damaged parts, and during the Italian Grand Prix, both drivers were instructed to ‘short-shift’.
The drivers were also told to select a ‘rain-mode’ setting, delivering smoother gear changes, which explains why Fernando Alonso remarked on Vettel’s flashing red tail light.
Red Bull was alerted to the problem after the telemetry showed high oil temperatures.
“Frankly, it’s a mystery,” admitted car designer Adrian Newey.
“Monza is particularly hard on the gearbox, but we’ve never had a problem like this,” he added.
“With Mark it was serious, while for [Sebastian] it was more of a precaution. It is possible that we will open his gearbox in the factory and everything is fine.”
Team boss Christian Horner added: “Caterham uses an identical gearbox and had no problems.” (GMM)
