What rear tail is that?

Artechnica: Bang on the money. Couldn't have said it better myself. Emissions was what killed the RX7 for sale in the states. Obviously they improved the design with the new Renesis motor.

Bob: Wrong again. First, "the points" you refer to are apex seals. They act like rings in a piston engine. They don't wear any different than rings in a piston engine. Detonation is what kills apex seals which is what usually is the problem when you have blown apex seals. To the best of my knowledge the apex seals have always been in a rotary engine. They were never "non replaceable" or fixed. The reason is that when the rotor rotates in the housing the edges (or points as you call them) have to move in and out in a groove on the edge of the rotor to keep contact with the surface of the housing. If they were fixed the rotor would bind. As for the lubrication, since oil is injected at the same time as fuel you should be getting lubrication right away. If you are really worried about lubrication just run pre-mix. I know people who do that because they don't always trust the oil injector system (mechanical failure). No disrespect but I think your mechanic friend is feeding you a line of BS. Like the statement I posted earlier there are a lot of "mechanics" that think they know what they are doing when it comes to rotaries but very few of them actually do.

Most rotary failures are due to overheating or detonation. Overheat a piston engine and you may have to replace a head gasket. Overheat a rotary and you are rebuilding the engine due to the engine design. Turbo rotaries are really risky when it comes to detonation and must be tuned by someone who knows what they are doing if you want it to be reliable. A normally aspirated rotary though will last and last until something else fails (cooling, etc.)

As for why Mazda isn't using it for all their cars just refer to Artechinca's response. Fuel economy and emissions pretty much killed it.
