Gary Anderson questions McLaren front wing

BBC Sport Formula 1 technical analyst Gary Anderson explains how the front wing affects the performance of an F1 car, and gives his verdict on why McLaren may be struggling with theirs.

The new McLaren car proved to be more than two seconds off the pace at the season-opening Australian Grand Prix, with Jenson Button and Sergio Perez finishing ninth and 11th respectively.

Anderson also runs the rule over the Red Bull, Lotus and Mercedes front wing.
