## What Cars Use a Rotary Engine?

The rotary engine, also known as the Wankel engine, is a type of internal combustion engine that uses a triangular rotor that spins within a figure-8 shaped chamber to create power. Rotary engines are known for their smooth operation, high power output, and compact size. However, they also have some drawbacks, such as lower fuel economy and higher emissions than traditional piston engines.

Only a few car manufacturers have ever produced vehicles with rotary engines. The most famous of these is Mazda, which has used rotary engines in a variety of models over the years, including the RX-7, RX-8, and Cosmo. Other car manufacturers that have used rotary engines include NSU, Citroën, and Mercedes-Benz.

## Advantages of Rotary Engines

Rotary engines have a number of advantages over traditional piston engines, including:

* **Smooth operation:** Rotary engines have no reciprocating parts, which means that they operate very smoothly.
* **High power output:** Rotary engines can produce more power than piston engines of the same size.
* **Compact size:** Rotary engines are more compact than piston engines, which makes them ideal for use in small vehicles.

## Disadvantages of Rotary Engines

Rotary engines also have some disadvantages, including:

* **Lower fuel economy:** Rotary engines are less fuel efficient than piston engines.
* **Higher emissions:** Rotary engines produce more emissions than piston engines.
* **Reliability problems:** Rotary engines have a reputation for being less reliable than piston engines.

## Conclusion

Rotary engines have a number of advantages over traditional piston engines, but they also have some disadvantages. As a result, only a few car manufacturers have ever produced vehicles with rotary engines. Mazda is the most famous of these manufacturers, and it has used rotary engines in a variety of models over the years. However, it is unclear whether rotary engines will ever become mainstream.
