G-Power has really out done themselves this time with their G-Power Hurrincane RR M5; The “World’s Fastest Sedan”. Recently, the Hurricane RR surpassed 372km/h equating to roughly 231mph. The high revving v10 makes 800hp with the help of 2 superchargers and a good deal of meticulous engine work. Accomplishing 231 mph in a big full-size sedan is no easy task but G-Power has made it happen. Their 800hp RR kit is, unfortunately, not available to the public; However, their RS kit capable of 750hp is… Just bring a check for ~$71,000. Aero kit and the tires required to withstand those high speeds, not included in price.
