...The RX 8 has the rotary engine. The "durability problems" were worked out by 1974 after 3 years of production. With the 70 cubic inch engine, 300 (SAE) horsepower at 10,000 RPM is routine. There are many older Mazda rotary engine vehicles on the road today, including the Rotary Engine Pickup.
And by the way, the Rotary Engine is an internal combustion Otto cycle engine.
Has anyone here heard of or seen this?
I remember the Wankel engine many years ago which was a rotary of German design. At least two Japanese automakers (NSU and Mazda) built cars using these. The engines were plagued with durability problems as new materials were needed for seals and such. The engine, pound for pound, put out more HP than piston types but never caught on and disappeared. This engine, as I understand it, is still in development and is primarily being designed for military applications. The engine is supposed be be quite light weight which lends well for aircraft use. I found this interesting.
In no way am I connected to or have I invested in this company (yet) BTW.
