Several prominent names are skipping the show this year, including the CEO of Fiat Chrysler, Sergio Marchionne. Other notable absences include the bosses of Ford, Volvo, Rolls Royce and Aston Martin.
Volkswagen's luxury brands Bentley and Lamborghini will also not be on display.
One reason for these notable absences is that the companies are planning to attend larger shows in the future instead.
"We believe it's a case of waiting for some of the bigger shows - Detroit in January, Geneva in March and CES in January too, which is having an increasing automotive presence given the growing amount of technology in cars," the auto analysts at BMI Research told CNBC via email. CES is a consumer technology and electronics show which occurs each January in Las Vegas, Nevada.
