Sauber will unveil the C34 with an online launch on January 30, two days day before 2015 testing begins in Jerez.
Sauber was one of the few teams to confirm its launch plans and will join Ferrari by breaking cover on Friday, which will take place at 10am Swiss time. The schedule for the Jerez test has also been confirmed by the team, with Marcus Ericsson in the car on Sunday and Wednesday and Felipe Nasr taking over in between.
Ericsson and rookie Nasr form a new-look line-up for Sauber this season, with reports suggesting the latter’s Banco do Brasil sponsors will have a big impact on the team’s livery. Nasr competed in a blue and yellow Carlin, the colours of the bank, in GP2 last year.
