The Hennessey GT Venom has just become the fastest production car in the world hitting 435.31 kilometres per hour (270.49 miles per hour).
Former racing driver Brian Smith powered the 7.0-litre twin-turbo GM-sourced V8 engined vehicle across the space shuttle landing strip at the Kennedy Space Centre to pip the old record set in 2010 by a Bugatti Veyron.
But his feat will not get the official stamp from the Guinness Book of Records which demands the car makes two runs over the flying kilometre.
NASA could not authorise a second run at the Space Centre for the team on the day.
Smith said he believed he could have gone even faster if the runway has been longer.
