Sauber has announced that it will launch its 2015 car online on Friday morning.
The Sauber C34 will be launched at 9am GMT on the same day that Ferrari unveils the SF15-T. Sauber also confirmed that the new car will run at the first test in Jerez, with its new driver line-up of Marcus Ericsson and Felipe Nasr sharing duties over the four days.
Ericsson - who tested for Sauber in Abu Dhabi last year after terminating his Caterham contract early - will drive on the first and last days of the test, with Nasr getting his first taste of Sauber machinery on days two and three.
The C34 will again be powered by Ferrari, with the team looking to bounce back from a disappointing 2014 season having failed to score a point at all last year, finishing 10th in the constructors' championship behind Marussia.
