Rotary engines

behvah78 · 12-30-2003, 05:55 PM

Is the RX8/RX7 the only cars with rotary engines? and What is the disadvantage to this kind of engine? I have heard that you need to warm it up more before accelerating.

RX-2, RX-3 and RX-5 too. Disadvantage: horrid emissions, gas hog, low torque, easy to break. And every car should be at operating temperature before hard acceleration.

*edit: and REPU too, Rotary Engined Pick-Up

Was there an RX-4?
First was the Cosmo 110 I believe, then the Cosmo Sport (6th car).

Emissions can be passed fine, but you lose power.
Bad fuel economy? Yes.
Useless below 3000RPM? Yes.
Unreliable? Generally, yes.

Fun? YES!!

Yeah, duh, the cosmo's too. mm.. 3 rotors

I heard that in late 60's a F1 team tried using rotary engines but they got bankrupt the next year since the car was too slow.

"Bad fuel economy? Yes"
The fuel economy of the RX8s doesn't look that bad. Its 20mpg. My grand am has the same city milage and a higher highway milage and only gives me 2/3 of that power. Am I missing something here?? By the way they both have the same curb weight.

The EPA is who does fuel economy ratings, not manufacturers. You will NEVER see what the EPA says the car does in ANY car.

Also a bit of history: Mazda is the only Japanese manufacturer to win Le Mans. Using a rotary powered car no less!

So does anyone know the real mileage for the RX8 cauz I'm thinkin of getting one.

MBTN · 12-31-2003, 03:24 PM

I'd say 14-17 average.

They say you have to let that oil circulate around the inside of the engine. It has a different oil flow than that of a conventional engine. I would let the engine warm a little BEFORE accelerating hard. But that's with EVERY type of car, isn't it?

technically you should be warming up the engine on every car before you drive it, but more so on a rotary powered car. its also not a bad idea to let the car cool down for a little while after you drive it before you turn it off.

I'd luv to see a mustang with a big rotary engine

spirit_r · 01-15-2004, 12:57 AM
