BBC's Humphrey, Coulthard and Jordan preview 2012 F1 season

BBC F1 presenter Jake Humphrey is joined by chief analyst Eddie Jordan and co-commentator David Coulthard to look ahead to the 2012 F1 season, which starts in Melbourne on 16 March.

The trio give their thoughts on the use of 'stepped' noses' as featured on several cars this season, designed to lower the nose to meet new regulations while increasing the airflow under the front of the car.

The team also predict Red Bull will face a "ferocious" battle from challengers attempting to surpass the reigning drivers' and constructors' champions.
