The Thailand International Motor Expo is the country's largest annual motor show, running for 13 days every December at IMPACT Challenger halls in Pak Kret, Nonthaburi (just north of Bangkok). The 2026 edition is the 43rd year of the event.
Every major automaker in Thailand sets up massive displays with their latest models, concept cars, and special-edition launches. Porsche, BMW, Mercedes-Benz, Toyota, Honda, and dozens more. It's where manufacturers drop their biggest promotions of the year, and many Thais time their car purchases around Motor Expo deals.
The show opens December 1 with a VIP and press preview, followed by a charity day on December 2 (100 THB admission), and then public days from December 3-13. Weekday hours run noon to 10pm, weekends and holidays 11am to 10pm.
Beyond new cars, Motor Expo features aftermarket accessories, performance parts, motorcycle displays, and special exhibition zones. The event regularly draws over a million visitors across its run.
