Caterham, last season the first F1 team to unveil its new car, will be one of a number choosing to launch at the opening test of 2013.

The Leafield-based operation will takes the wraps off its CT03 - interestingly not CT02 as would have been the case had it numbered its race cars sequentially without regard to its new road models - in the pit-lane at Jerez on Tuesday 5 February, immediately ahead of the first day of testing.

Caterham is the ninth team to set a launch dates for its new car, after Mercedes, Toro Rosso and Williams confirmed slots late last week. Only Lotus and Marussia remain to confirm their schedules, but both are reported to be on target to appear with their 2013 models in Jerez. Williams therefore looks likely to be the only team not to make the opening test with its new machine, while Marussia, Caterham and Force India all have to name a second driver.
