Force India have released a side-on image of their VJM07, showing off a new, blacker livery while avoiding a front-end view. They said the front of the car was a temporary solution and would look very different for the start of the season in March.

The team will have Sergio Perez of Mexico and Nico Hulkenberg of Germany as drivers in 2014 after dropping 2013 drivers Adrian Sutil and Paul di Resta. Perez comes from McLaren and Hulkenberg returns to Force India after a year driving for Sauber.

Perez is quoted by the team as saying the beginning of the new season is "a very big opportunity" for the team as new regulations and new engines create a fresh start for all the teams.

The new cars will hit the track for the first time in testing at Jerez in southern Spain next Tuesday but some teams are discreetly presenting them this week online.

The technical rules have changed significantly this season and cars have to combine a high chassis and low nose tip, which can be much narrower than last year. There has already been talk of 'anteater-style' solutions.

McLaren are due to reveal their car on their website on Friday , with Ferrari following in similar fashion on Saturday and Sauber on Sunday.
