Yes, but those are production-based series, so of course would allow factory-style engines. But as far as I know rotaries have been outlawed in the Le Mans series.Lighter and more compact. Lower C of G and better weight distribution and centralization. Also the RE Amemiya FD has been using a rotary in the Super GT series and JGTC when it was called that. Then there's the Formula Mazda series in the states that use relatively stock rotaries out of the RX-8.
Why do you think they are unreliable?
Technically they're very reliable, just short-lived like I said. If you've got a built and turbod rotary you can predict exactly what will go wrong, and when.Perhaps it's because of their high tendency to be unreliable.

Can anyone help me ID this car? I saw it in the Meguro ward of Tokyo, Japan. Not sure what it is though... I want to say a Datsun Blue Bird, but I think that's wrong.

an old datsun sunny truck i beleive.
There aren't any timing belts to tension, no valve lash to adjust, no rockers or lifters or pushrods or any sort of drivetrain that could potentially develop problems. There are three moving parts and provided you keep them oiled they'll hold their compression for 200,000 miles with half the maintenance required of a piston engine. Everything is short lived once you start adding power though.Riiiight.

From what I've seen, they seem to last longer if you run the piss out of them on a regular basis. Weird, but coming from someone who works on Mazdas, he says the ones that come in with problems are usually the ones owned by old people who never drive them hard.the NA models are fine. The Turbo rotaries are the problem.
That's pretty much true for most cars.From what I've seen, they seem to last longer if you run the piss out of them on a regular basis. Weird, but coming from someone who works on Mazdas, he says the ones that come in with problems are usually the ones owned by old people who never drive them hard.
Fuel consumption goes up and down just like anything, and oil consumption depends on rpm so those aren't really reasons. The main reason is because rotaries' compression ratio varies with rpm - at lower rpm the compression is actually mighty low. The engines run very dirty down there and carbon buildup can muddle its performance. It's quite noticeable so you have to rev it out every now and then to keep it clean.The other thing I've heard from rotaries is that whether you potter around at low speeds or thrash them, fuel and oil consumption is pretty much the same. So you may as well thrash them.
Is that smoke coming from the tires or from the failed apex seals?J/K..
