Daredevil businessman Zef Eisenberg may have started braking too soon in the moments before he died while attempting to break a speed record in a Porsche 911 Turbo, an inquest heard.
The 47-year-old was trying to prove he had created the world's fastest Porsche when he was killed in a crash at Elvington Airfield, near York on October 1, 2020.
An inquest in Northallerton heard Mr Eisenberg was trying to break a number of land speed records in the "extensively modified" car.
