Do rotary engines have good gas mileage?

More of the heat from combustion is lost to the coolant cooled cylinder walls in a rotary engine and thus unavailable for use as work energy. There are two problems with rotary engines, one is bad gas mileage, the other is bad reliability.

Why is Rotary bad?

Rotary engines have a low thermal efficiency as a result of a long combustion chamber and unburnt fuel making it to the exhaust. Finally, emissions are poor and fuel economy is terrible, and ultimately this is the cause of it’s death.

How many MPG does a rotary engine have?

Mazda presented a report by J. D. Powers and Associates, a Los-Angeles research firm, indicating a majority of owners of the rotary engine Mazda were getting 17 miles per gallon in city driving and 20 miles on the highway.” The fuel economy for this vehicle was originally reported as 10.7 mpg due to a clerical error.

Are rotary engines worth it?

Rotary engines are high-revving and can produce a lot of power in the right hands. They are easy to modify, customize, and build, and you can do so pretty inexpensively to create a fast car. Rotary engines are used in a lot of pro-compact drag racing cars because they can handle an absurd amount of power.

Will Mazda make another Rotary?

Come early 2022, albeit in hybrid form in the upcoming 2022 model year MX-30 range-extender version (in which the rotary engine acts as a generator only), Mazda will add this new rotary-range-extender model to their current MX-30 gasoline-hybrid and fully electric lineup that will land in U.S. showrooms later this year …

What killed the rotary engine?

When you put it all together, emissions killed off the rotary. The combination of inefficient combustion, inherent oil burning, and a sealing challenge result in an engine that’s not competitive by today’s standards on emissions or fuel economy.
