However, the Veyron SS is still recognised by the Guinness Book of Records as the world's fastest production car as the tome defines a 'production car' as one of which at least 30 units will be built, and Hennessey is building only 29 examples of the Venom GT.
Be that as it may, Texas-based Hennessey Performance is still trumpeting its feat by offering a 'World's Fastest Edition' variant of the Venom GT. Exclusivity is guaranteed, as just three examples will be built and sold.
Each unit commands an outlay of $US1.25m, but you can put the chequebook away, because all three cars have allegedly been pre-sold.
As for the 'World's Fastest Edition' moniker, it also alludes to the Venom GT's spine-compressing 13.63sec sprint from standstill to 300km/h – a feat that has earned it a spot in the Guinness Book of World Records.
Although mechanically unchanged from the standard Venom GT, the limited-edition model features red-white-and-blue stripes to leave onlookers in no doubt about the car's country of origin.
"The Venom GT is America's supercar and it broke 270mph (434km/h) on the same runway where the Space Shuttle landed at the Kennedy Space Center," said company founder John Hennessey.
"We wanted to offer a special paint scheme that would incorporate the colours of the American flag – the same flag we flew on the Space Shuttle runway. Thus, our special livery package includes a body in white with red and blue stripes."
The Venom GT's formula for achieving the speeds it is capable of is simple: huge power, minimal weight.
The low-slung two-seater's thumping 7.0-litre twin-turbo V8 cranks out 928kW, and this massive quota of kilowatts is tasked with propelling just 1247kg (almost 200kg less than a Lotus Evora S).
The key to the car's waiflike mass is down to lightweight aluminium construction, carbonfibre bodywork and featherweight carbon-ceramic brakes.
"We're thrilled about what we achieved at Cape Canaveral with the Venom GT," said Hennessy CEO Don Goldman, "and now the World's Fastest Edition is a living, breathing celebration of that record achievement."
According to US reports, Hennessey is now contemplating an excursion to the Nurburgring Nordschleife to see how the Venom GT stacks up against other hypercar luminaries – such as the McLaren P1 and Porsche 918, both of which have already dipped under the elusive seven-minute mark.
