Sounds promising!

https://en.wikipedia.org/wiki/Homogeneous_charge_compression_ignition



"Homogeneous charge compression ignition (HCCI) is a form of internal
combustion in which well-mixed fuel and oxidizer (typically air) are
compressed to the point of auto-ignition. As in other forms of
combustion , this exothermic reaction releases chemical energy into a
sensible form that can be transformed in an engine into work and
heat."

Automotive-HCCI-Engine-Laboratory

"HCCI combines characteristics of conventional gasoline engine and
diesel engines. Gasoline engines combine homogeneous charge (HC) with
spark ignition abbreviated as HCSI. Diesel engines combine stratified
charge with compression ignition abbreviated as SCCI."

I hope it won't be called an Rx-9. Mazda has already made an Rx-9,
back in '77-'81 it was also called the Luce and it failed.

The concept looks more like a descendant of the 3rd Gen Rx-7, which
is well known and respected through-out the world.... So, my fingers
are crossed that it'll be a 4th Gen 7.

RX9 make more sense for the new buyers.

Mazda needs to get serious about the heat rejection to the coolant if
this is going to work. They need to use  stainless steel for the
rotor housing liner and the rotor. Stainless has a much, much lower
coefficient of heat transfer than steel. It was cold this morning and
I much appreciated the RX8 fast warm up and hot heater :)

Like Windows, it should be called RX10, :-)
