The Caterham team owner Tony Fernandes has warned that he could walk away from Formula One unless his tail-end team showed significant improvement this season.
The Malaysian entrepreneur, who also runs Queens Park Rangers football club and the AirAsia airline, says there wouldn't be any point carrying on if the team remained uncompetitive.
Caterham came into the sport as Lotus Racing with two other new teams in 2010 when a budget cap was talked about and then abandoned.
None have scored points in four seasons and Spanish-based HRT folded at the end of 2012.
Last year, Caterham finished last of the 11 Formula One teams while QPR were relegated from the Premier League.
Caterham will have two new drivers this year in Japan's Kamui Kobayashi and Sweden's Marcus Ericsson.
Fernandes compared Formula One unfavourably to football, saying it was too predictable, too expensive, not exciting enough and with insufficient chances for underdogs to create an upset.
