Sauber will reveal its 2013 F1 car, the C32, in the days before it makes its track debut at the start of (northern) winter testing.
Team founder Peter Sauber had already announced that the new Ferrari-powered single-seater will run for the first time at Jerez on February 5, 2013.
The team on Thursday invited the media to an official launch event at its Hinwil, Switzerland, headquarters.
Nico Hulkenberg, Sauber's new driver to replace Sergio Perez, has already had his seat fitted. His team mate will be Mexican rookie Esteban Gutierrez.
CONTENDERS ONCE AGAIN
McLaren-bound Perez, who reached the podium three times in 2012, was quoted by Swiss magazine Speed Week as stating that: "Sauber will be strong again, I am firmly convinced. The rules are fairly stable, the team has understood its car well, so why should they be worse than 2012?
"I even think there could be races they are capable of winning."
"Sauber has done a lot for me, so I want them to do well more than any other team - with the exception of McLaren, of course!"
In other pre-season testing news, Reuters correspondent Alan Baldwin wrote on Twitter that he believes Mercedes has booked the Jerez circuit for filming on the day before the first official test begins.
"Wonder who will be first in the car," asked Baldwin, contemplating Mercedes' 2013 line-up of Lewis Hamilton alongside Nico Rosberg.
