What is the advantage of a rotary engine?
Due to its revolutionary motion, a rotary engine operates with less vibration than a piston engine. This allows rotary engines to be tuned to run at higher rpm, thus producing more power. Another advantage of the rotary engine is that in the event of a breakdown, the engine will not seize up.
What’s the difference between rotary engine and a normal engine?
Modern automobiles will normally have either a piston engine or a rotary engine. Piston engines have up-and-down moving pistons that convert pressure into rotational motion, whereas rotary engines feature a radial layout with an odd number of cylinders.
Are rotary engines good engines?

Why was the rx7 discontinued?
Unfortunately, the RX-7 was discontinued in most of Europe by 1996 due to emissions regulations, although Mazda continued to produce cars for some markets, eventually boosting power output on later Japan-only models to as high as 280PS. The year 2002 marked the end of one of the most exceptional sports cars in history.
