Before this, the best top speed record for a sedan car was 362.4km/h by Mercedes bi-Turbo V12 Brabus Rocket. Now the new record holder is a speed of 365.7km/h which is equivalent to 228.4mph by a 750hp G-Power M5 Hurricane RS. Now that is some serious number for a BMW. The M5 Hurricane RS is upgraded by G-Power by adding high capacity twin superchargers with a boost level of 0.8bar. According to CEO of G-Power, they can still improve the performance of the M5 by raising the boost to 1.0bar. But only if they ever need it..
