After SSC North America’s disputed top speed run of 331 mph, they’re back again to prove their Tuatara is the real deal. The team traveled to the Johnny Bohmer Proving Grounds at the Kennedy Space Center Shuttle Landing Facility in Florida. This allowed them to utilize the 2.3-mile strip for their top speed run, which is obviously less than what State Road 160 afford them (7 miles). Joining the SSC team was Racelogic USA. In fact, it was Jim Lau, Technical Director of Racelogic USA in North America, who installed and verified the data logger (Racelogic VBOX 3i 100Hz GNSS system).
Their Northbound run resulted in a max speed of 279.7 mph and the Southbound run had a max speed of 286.1 mph. Combined, the two-way average is 282.9 mph. This speed puts it 5 mph over the Koenigsegg Agera RS which had a two-way average of 277.9 mph. You can see the runs for yourself, complete with onboard video speed overlay collected using a VBOX Video HD2.
