they have been working on a wankel rotary engine for almost 70 years.
Someday they get one that not only works but scales up in production.
Seems to me that the tools are now available to make that happen.
I have no clue as to whether this is the “One”.
Looks like this approach may solve the seal problem.
I remember that an automotive company produced a line of small pickup trucks powered by a Wankel engine. A guy in my battalion had one. Do you remember which company it might have been. The guy liked it.
On a related note, AMC intended to use a Wankel engine in the Pacer.
Co-worker of mine traded in his 1988 Fiero GT (The year they finally got it right) for an RX7. I’ve never driven an engine that had such a perpetual power curve. It just smoothly hummed to the red line while you were pressed into the seat. Unfortunately every 20K it was in the shop for engine overhauls. A very bad-ass car. It’s reliability though made it British, instead of a Japanese product.
Did Mazda vehicles once have a type of rotary engine?
