Model likely hit a top speed in excess of 271 mph.

Hennessey Performance is celebrating its 25th anniversary by announcing the Venom GT Spyder has set a new world record.

An official announcement is scheduled for Monday April 11th but the teaser video suggests the car beat its previous speed record of 270.4 miles per hour which was set at the Kennedy Space Center in 2014.

Nothing is official but Hennessey used last year's SEMA Motor Show to introduce an updated version of the Venom GT Spyder.  It features an improved biturbo 7.0-liter V8 engine which can run on E85 Flexfuel.  This change enables the engine's boost pressure to be increased from 19 pounds per square inch to 26 psi.

The engine produces an impressive 1,451 horsepower which is an increase of 207 hp.  The company estimated it will enable the car to accelerate from 0-60 miles per hour in 2.4 seconds before hitting a top speed in excess of 280 mph.

If that latter figure pans out, the Venom GT Spyder will easily beat the Bugatti Chiron which is electronically-limited to 261 mph in Top Speed mode.  However, it is important to note Bugatti has previously said the limited top speed is "by no means the end of the road" for the Chiron.
