Ferrari introduces bold update for Russian GP

Ferrari has unleashed one of their biggest upgrades of the season for the Russian Grand Prix on Sundy, with a revamp to its front wing plus some experiments for next season also.

Ferrari are desperate for a positive result in Sochi, with Lewis Hamilton and Mercedes running away with the two championships.

The front wing is completely brand new and features a combo of ideas that have been used on Red Bull and McLaren cars in the past.

Another change for Ferrari is the turning vane, which is also looking ahead to next season.

Ferrari's change is definitely an aggressive one with Scuderia clearly determined to make this weekend their's.

Sebastian Vettel was the quickest in the first practice session earlier this morning and he'll be desperate to carry out that form for the rest of the weekend - being 40 points adrift of Hamilton in first place.
