A CO2 gas-propelled model car launcher permits two or more model vehicles to be launched substantially simultaneously. Launching of the vehicles is achieved by moving a trigger plate sidewise which disengages a disc and thereby releases a firing pin whose forward movement punctures the CO2 cartridge. A height adjustment feature permits the launcher to accommodate model cars of different sizes. Multiple launchers may be ganged together and their trigger plates rigidly connected in such a way that sidewise movement of one trigger plate launches all of the model vehicles.
