Mazda is quite clear that the RX-Vision might never go on sale

Thanks for explanation as I was always wondering how those parts getting lubricated. In this case Wankel engine, like two-stroke engine, will have a hard time to pass current stricter emission standards!

I imagine that is one big hurtle, yes. Ironically, a lot of RX-7 owners, myself included, add two-stroke engine oil to the gas tank at fill-ups. Ratios vary but 1 oz oil to 1 gal fuel is pretty much the standard. Racers use more, those with still-function oil injection systems use less.

Didn't know that! But if you put two-stroke engine oil to the gas tank, does it cause blue smoke from the tail pipes as I still remember those motorcycles with two-stroke engine in the old days had always had a lot of blue smoke following it!

That's where the proper ratio comes into play. Anything higher than 1:100 oil:fuel ratio tends to produce noticeable smoke in my opinion. I run 1 oz oil to 1 gal fuel, which is 1:128, and I only notice a small amount of smoke during cold start up. Compared to old two-stroke dirt bikes even 1:50 isn't bad. I'd really like to have a functioning oil injection system in my car but that involves either rigging up one of the older mechanical systems or upgrading my ECU to run the newer electronic units. It's fun getting strange looks while pouring oil into the tank at gas stations though.

The torque of a hamster wheel and the fuel economy of a big block. What's not to like.

The engine in our CX-5s is somewhat different then the piston engines available to us in the 80s. I look forward to driving and owning a Mazda with a new rotary engine. I suspect that one feature it will share with the old ones is it will be a blast to drive.

I really want to own one, too! I've owned pushrod, cam-in-block sports cars and a supercar, and cam-less VVT, and I'd like to add rotary to the list.
