A big advantage is its reliability, because the slow movements of the inner parts of the engine and the low vibration, thanks to the only rotor that gives the motion...
Um..... the cars that have come with rotaries in the past have had very poor reliability. In all previous Mazda RX models, the apex seals (they are like piston rings for a rotary) wear out quite frequently(under 100,000 miles, alot of the time). It's over $1000 just for the parts when these break, and if you're paying someone else to put them in the price is outrageous. Meanwhile any American V8 or Japanese 4, 6 cylinder can go 200k miles with no internal engine work.
