Certainly! The Mazda RX-7 is renowned for its rotary engine, also known as the Wankel engine. Here's a detailed overview of its characteristics and workings:

### Rotary Engine Basics

1. **Design**: Unlike conventional piston engines, which use reciprocating pistons to generate power, the rotary engine uses a triangular rotor that rotates within a chamber. This rotor completes three faces of an epitrochoid curve (a curve traced by a point on the perimeter of a circle rolling around another fixed circle).

2. **Rotary Motion**: The rotor, driven by combustion, rotates around a central shaft. This rotary motion is where the engine gets its name.

3. **Advantages**:

   - **Smooth Operation**: Rotary engines are known for their smooth and high-revving nature due to their balanced rotational motion.

   - **Compact Size**: They are more compact and have fewer moving parts compared to piston engines of similar power output.

   - **High Power-to-Weight Ratio**: Rotary engines can achieve high power outputs relative to their size and weight.

   - **High RPM Capability**: They can rev higher than most piston engines, which contributes to their performance characteristics.

### Mazda RX-7 Rotary Engine Specifics

1. **Type**: The RX-7 typically used a twin-rotor Wankel engine (13B-REW for the third generation FD model).

   

2. **Displacement**: The 13B rotary engine used in the RX-7 has a displacement of 1.3 liters (654 cc per rotor).

3. **Turbocharging**: In some models

The top speed of the Mazda RX-7 varies depending on the specific model and generation. Here are some general figures based on popular models:

1. **First Generation (SA/FB, 1978–1985)**:

   - The top speed of the early RX-7 models with the 12A rotary engine typically ranged from around 120 to 125 mph (193 to 201 km/h).

2. **Second Generation (FC, 1986–1992)**:

   - The turbocharged models, especially towards the end of the FC generation, could achieve top speeds in the range of 140 to 150 mph (225 to 241 km/h).

3. **Third Generation (FD, 1992–2002)**:

   - The FD RX-7, particularly the later models equipped with the twin-turbocharged 13B-REW engine, had higher top speeds. It's reported that these models could reach top speeds exceeding 160 mph (257 km/h).

These figures are approximate and can vary based on factors such as engine tuning, modifications, aerodynamics, and road conditions. The RX-7's lightweight design, aerodynamic shape, and powerful rotary engines contributed to its impressive performance capabilities, especially in terms of acceleration and handling at high speeds.
