2. Geneva International Motor Show – Geneva, Switzerland
3. Frankfurt Motor Show (IAA) – Frankfurt, Germany
4. Tokyo Motor Show – Tokyo, Japan

Keep in mind that this is not an exhaustive list, and other significant automotive trade shows might emerge in the upcoming years, or currently popular ones could be discontinued.
