Video: Have You Ever Heard What a Six-Rotor RX-4 Sounds Like?

https://www.youtube.com/embed/UNy5L6Qow4M

The Mazda RX-4 originally came from the factory with a two-rotor Wankel engine said to be good for around 130 horsepower. This RX-4, however, is about as far away as one can get from the factory version, packing six rotors underneath its hood.

What do all those extra rotors do? Make noise, apparently (headphones users beware).

Heh. When I saw the engine I thought "they're either in NZ or in Puerto Rico".

Canoe bump?

There are a couple more 6 rotors in the world now.

Japanese shop Anniversary Racing Factory's Eunos Cosmo and a BMW from South Africa:

All that dust being sucked back into the open inlets during the dyno pull... sigh.
