Sure it's no production car, but given that Hennessey did basically the same thing with the Venom GT, then the above car could theoretically also become the undisputed world's fastest production car had the base Ford GT been still built. What's amazing is the car did it half the length of track than the Venom GT but it's rated at 2000HP.
