“We came pretty close to meeting the theoretical numbers, which is astonishing to do in a real world setting on a public road.

Its performance reflects the dedication and focus with which we pursued this achievement,” Shelby said in a news release. “It’s been 10 years since we held this record with our first car, the Ultimate Aero, and the Tuatara is leagues ahead. Officials were on site to verify all world record criteria was met - including review of Dewetron GPS measurements, which tracked the speed runs using an average of 15 satellites - and to confirm the new record.Ĭompany owner Jerod Shelby said it was monumental for him and his 24-employee company. The crosswinds are all that prevented us from realizing the car’s limit.” As I told Jerod, the car wasn’t running out of steam yet. “As I approached 331 mph, the Tuatara climbed almost 20 mph within the last five seconds. And with better conditions, I know we could have gone faster,” Webb said in a news release. He said the Tuatara could have gone even faster. 'We are entering a time when we are no longer faced by the limit of machines, but by the human factor.' 'Accomplishing a feat of engineering that pushes the limits of a road-legal car by a margin this large is both exciting and inconceivable, even to me,' Webb said. The milestone surpasses the 278 mph (447 kph) reached by Swedish car company Koenigsegg Automotive in 2017. The car produces 1,750-horsepower and costs $1.9 million. Guinness World Records said Richland-based SSC North America's Tuatara model is the fastest production car.
