Bangkok hosts the most prestigious motor shows in the region. Each year, there will be two main international level motor shows in Bangkok - the Thailand International Motor Expo organized by Inter-Media Consultants is usually held between November-December, and Bangkok International Motor Show organized by Grand Prix International Group, usually held between March-April.

Bangkok International Motor Show (BIMS) is an OICA sanctioned event. OICA is short for Organisation Internationale des Constructeurs d’Automobiles or International Organization of Motor Vehicle Manufacturers, and is the only body that collectively represents the global automotive industry. The organization's exhibition committee coordinates international motor exhibitions.

This year, the 33rd Bangkok International Motor Show 2012 will be held between 28-March to 8-April at Impact Muang Thong Thani exhibition center (Hall 1 to Hall 3).

The theme for this year's event is "Technology Difference." Mitsubishi will be launching its eco-car, previewed as the Mirage at last year's Tokyo Motor Show while Suzuki will be unveiling a still-secret eco-car. Hyundai will be launching all new the Elantra sedan and while Ford will debut its new generation Thai made Focus.

650 models will be on display. Participating manufacturers include BMW, Chevrolet, Ford, Honda, Hyundai, Isuzu, Kia, Lexus, Lotus, Mazda, Mercedes-Benz, MINI, Mitsubishi Motors, Mitsuoka, Nissan, Peugeot, Rolls-Royce, SsangYong, Suzuki, Thairung, Toyota, Volkswagen and Volvo. Even Rolls-Royce will be participating for the first time.

According to the organizers, Proton, which participated last year, will be skipping this year's BIMS. The reason cited was lack of budget from Proton's local distributor Phranakorn Auto Sales and no support from parent company Proton.

Participating bike manufacturers include Big Bull, BMW, Ducati, Harley-Davidson, Honda, Kawasaki, Modern Bike, Stallions, Suzuki, UDA, Vespa and Yamaha. Ducati and Harley-Davidson are participating for the first time.
