World's Fastest Production Car

The Hennessey Venom GT.

The Hennessey Venom GT hit 427.6km/h during testing at a naval air station in the United States, which the manufacturer says makes it the world's fastest production vehicle.

Hennessey used two VBOX 3i data logging systems to measure the exotic hypercar's speed and had VBOX officials present to certify the figures. The top-speed run was accomplished over a distance of two miles (about 3.2km) using a full-production Venom GT.

"While a Veyron Super Sport did run 267.8mph (430.9km/h), Bugatti speed-limits its production vehicles to 258mph (415.2km/h)," said company founder and president, John Hennessey. "Thus, at 265.7mph (427.6km/h) the Venom GT is the fastest production car available to the public."

Venom GT is powered by a 7.0-litre V8 engine fed by twin turbochargers that team to produce 928kW and 1564Nm of torque at 19 psi (1.3 bar) of boost pressure.

Hennessey plans to only build a total of 29 Venom GTs.
