The SSC Tuatara currently holds the title as "Fastest Production Car" in the world, independently measured and validated by Racelogic.
Racelogic USA was contracted by SSC North America to provide technical assistance with measuring and validating high-speed test runs of the SSC Tuatara during testing and record attempts conducted with Johnny Bohmer Proving Grounds at Space Florida’s LLF, Kennedy Space Center, Merritt, FL on January 17th, 2021. Speed and time data was collected with a Racelogic VBOX 3i 100Hz GNSS system, accurate to ±0.06 MPH, and traceable to ISO standards for speed measurement. The data logger was installed and data was verified by Jim Lau, Technical Director – North America of Racelogic USA. Onboard video speed overlay was also collected during these runs using a VBOX Video HD2 for further correlation, and is available publicly.
