SSC Tuatara Hits 282.9 MPH In New Top Speed Run To Prove Naysayers Wrong ++ That's the average of two runs, with the absolute top speed being 286.1 mph. With the Tuatara’s original top speed attempt tarnished by controversy, SSC North America had no other way but to redo the run. In an attempt to clear up any accusations about tampering with the video footage of the original run that took place last October, the hypercar marque now claims it has legitimately set a new top speed record during a second official run. Rather than going back to the Nevada State Route 160 where the first attempt took place, SSC gained access to the Johnny Bohmer Proving Grounds at Space Florida's Shuttle Landing Facility. We’ve covered our fair share of top speed runs that took place at the former Space Shuttle runway in Florida, but no other car has gone faster than the Tuatara.
