Hit a top speed of 265.6 miles per hour.

Hennessey Performance is celebrating its 25th anniversary by announcing the Venom GT Spyder has become the world's fastest convertible.

The world record was set on March 25th when a Venom GT Spyder driven by Ford Performance Racing School director Brian Smith hit a top speed of 265.6 miles per hour.  This is slower than the car's claimed top speed but it easily beats the previous record of 254.04 mph which was set by the Bugatti Veyron Super Sport Vitesse.

The Venom GT Spyder is powered by a biturbo 7.0-liter V8 engine that produces 1,451 horsepower and 1,287 pound-feet of torque.  It is connected to a six-speed manual transmission which enables the car to accelerate from 0-60 mph in less than 2.4 seconds.

In order to commemorate the new world record, Hennessey will offer three Venom GT Spyder World Record Editions.  The company declined to release details but confirmed each model will be priced from $1.3 million.

In a statement, John Hennessey said "I thought that this would be a special way to celebrate 25 years of making fast cars faster."  He also noted "This was a great way to validate the technical excellence of our car which includes high-speed stability with an open roof.”
