«It's nothing we shouldn't be able to fix,» said Bottas, who won 10 grands prix over his five years at Mercedes as team-mate to Lewis Hamilton. «It feels like we are in the very early stages of discovering the car.

The new Alfa Romeo is the final car to be unveiled after the introduction of F1's revolutionary new technical regulations this year.

It features a number of design solutions already seen on other cars, from a «scoop» front wing similar to the McLaren, to the undercut side-pods with extensive
