SSC Tuatara 508.7km/h speed record claims were "substantially incorrect"

Last week CarAdvice reported the SSC Tuatara had broken the production car land speed record in the Nevada desert with an average speed of 508.7km/h in two directions. Now, the legitimacy of that achievement has been cast into doubt. Based on the known distance between set points along Nevada’s Highway 160 – and the amount of time it took for the car to reach them – high-profile YouTuber Shmee150 estimated the Tuatara’s peak speed was no higher than 450km/h.
