Video: Mazda rotaries keep singing

Among the bevy of engine sounds that fill the motorsports landscape, the Mazda Rotary that powered the 767B prototype and RX-7 GTO cars of the early 1990s hold a special place in the hearts, and ears, of enthusiasts. Those four-rotor engines had a unique wail that set them apart from others in the IMSA fields of the time.

Today, Mazda Heritage Collection is painstakingly restoring and running those cars – with others to come – at historic racing and events around the country. In this short video, we get an inside look at what it takes to keep these magnificent and unique machines on track for all to see, hear, and enjoy.
