Billed as one of the biggest car shows in the world, it is set to run from March 3rd to 13th at the Palexpo convention centre next to the Geneva airport.
According to a tally by the ATS news agency, the number of exhibitors has fallen annually since 2013, when there were 260.
But André Hefti, the car show's general manager, said earlier this week that there was no space left for extra exhibitors.
All of the 77,323 square metres of exhibition space in Palexpo's seven halls was taken.
More than 120 world and European car models will be premiered at this year's show, which is expected to attract between 650,000 and 700,000 visitors.
Non-refundable tickets for admission are available online ranging from 16 francs for adults to nine francs for children from six to 16, pensioners and the disabled.
A group rate for more than 20 people costs 11 francs per person.
Tickets are available from other sales points, including Swiss Federal Railways (SBB), which offers reduced rail fare-admission fee packages.
