Formula 1 - Lotus plotting championship charge after launch of E21

Kimi Raikkonen says Lotus are aiming to "win more races and fight for the championship" after launching their new car for 2013.

The Finn finished third in the drivers' championship last season but wants to add to his maiden title from 2007, with team principal Eric Boullier saying their target is to "break into the top three" of the constructors' championship in addition to more race wins.

Lotus earned a first victory in their current guise at the Abu Dhabi Grand Prix, but finished fourth overall behind Red Bull, Ferrari and McLaren.
