McLaren repeat: No need for alarm bells

McLaren insist there is no need for "alarm bells" after the team's MP4-25 was spotted with a rather unusual device attached at Jerez on Wednesday morning.

Concerns were raised about McLaren's 2010 challenger at the first pre-season test at Valencia last week when the MP4-25 was splashed with 'fluminescent' paint.

This paint is often used by teams to get a better understanding of a car's aerodynamic shortcomings, however, McLaren were quick to insist that there is "no cause for alarm."

Less than a week later and the team is once again having to deny problems after Jenson Button took to the Valencia track on Wednesday morning with a strange sidepod structure on his car.

The device, which is used for measuring aerodynamic flow structures, once again had McLaren putting out fires before they started.

A team spokesman told Autosport that there is no need for "alarm bells", adding that it is "normal engineering work.

"Given the limited amount of testing that teams have been permitted over the past two seasons, as a team we feel it's necessary to put as much emphasis as we possibly can on accurately measuring the flow structures we encounter at the track so that we can match them to the flow structures we are able to simulate in CFD and the windtunnel back at the factory."
