Given the horsepower and weight of the Ibishu 600 Miramar Sport Roadster with a Wankel One-Rotor engine, it's reasonable to estimate its top speed to be in the range of 165-170 kilometers per hour (approximately 102-106 miles per hour). This aligns with the capabilities expected from such a lightweight sports car with an efficient rotary engine design.
