The storyline is described by the publisher as being in the vein of The Fast and the Furious, with a bit of Initial D and Speed Racer mixed in.  The main character is a taxi driver with incredible driving skills, who hates racing due to the death of his famous racing father.

Topspeed features the work of creators George Lau, Man Wai Cheung and Wai Kit Leung, who have also contributed to Saint Legend, Heaven Sword & Dragon Sabre and Black Leopard.
