Thailand's Longest Running Modified Car Show
XO Autosport is Thailand's longest running modified car show brand, organized by Grand Prix International PLC. XO Autosport Thailand's flagship show grew out of the XO Autosport magazine, which has been published for over 30 years, making it one of the most recognized names in auto tuning culture across Southeast Asia.
What started as a print publication covering Thai auto tuning expanded into a full-scale live event series, bringing the magazine's audience face to face with the cars, builders, and brands they had been reading about. The annual flagship show takes place at IMPACT Muang Thong Thani in Nonthaburi, just north of Bangkok. It has become a home event for the country's tuning community, and XO Autosport Thailand's reach now extends well beyond Bangkok thanks to satellite meets around the provinces.
What Cars Are on Display?
The show fills multiple halls with hundreds of custom vehicles. The floor covers everything from JDM street builds and widebody kits to full engine swaps, air suspension setups, and concours-level restorations. Builders from across the country bring their best work, and the standard of preparation is consistently high.
Cars are judged across categories including best engine bay, best interior, best paint, and overall best in show. The quality of builds on display rivals anything you would see at SEMA or Bangkok Auto Salon. For enthusiasts of turbocharged performance cars or Japanese imports with extensive modifications, this is where the auto tuning community puts its best work on public display.
Souped Up Zone and Live Entertainment
The show combines a modified car competition, an aftermarket parts expo, and live motorsport entertainment under one roof. Vendors and performance shops sell parts, accessories, detailing products, and auto tuning tools. Major aftermarket brands use the event to launch new products and run promotions you will not find anywhere else.
The Souped Up zone has become a signature feature and is the single biggest draw for younger fans. Souped Up, also operated by Grand Prix International, focuses on motorsport and performance. Expect souped engines on the dyno, live drifting demonstrations, souped up revving competitions, and crowd-focused activities throughout the weekend. The Souped Up brand also runs smaller events at venues across Thailand during the rest of the year, which keeps the auto tuning scene visible outside of the main annual show.
For anyone building a project car in the region, this is the best place to see what is available and talk directly with suppliers. The event draws serious entries from builders who spend months preparing for competition day. XO Autosport Thailand's reputation pulls in auto tuning shops from across the country who set up booths to showcase their latest work and connect with customers.
Where Is the Show Held?
IMPACT Muang Thong Thani is in Pak Kret, Nonthaburi, roughly 30 minutes from central Bangkok depending on traffic. Parking is available on site, though it fills quickly on event days. The indoor exhibition halls mean the show runs rain or shine, making it a reliable home for the annual gathering.
The venue is also home to the Bangkok International Motor Show, the IMPACT Speed Classic, and several other major automotive events throughout the year.
How to Attend
The main show typically takes place between March and July, with the exact dates and theme changing each edition. General admission is usually 100 to 200 THB. International visitors will find the event easy to navigate. English is spoken at most vendor booths, and the food vendors and open seating areas make it a comfortable day out.
