The American tuner does not seem too worried, as its Venom F5 is rumored to hit the 300 mph mark.

Hennessey has commended Koenigsegg for breaking the Venom GT's speed record.The Swedish supercar builder brought its Agera RS to Hennessey's home country, shutting down a long stretch of Nevada highway to record a two-way average of nearly 278 mph and a top speed of 284 mph.

Hennessey's Venom GT in 2014 claimed a top speed title with a 270-mph run at the Kennedy Space Center's 3.2-mile landing runway. The company claimed the car was still pulling until it ran out of road, however the achievement did not earn official Guinness status without a two-way average and a production run of more than 30 units.

Speaking to Top Gear, John Hennessey praised his Swedish rival for the record-setting run.

"Those guys crushed our number and I think it's great," he said. ""Christian did it right. He just played it cool and built a dedicated car to smoke everybody."

The rivalry between the Swedes, Americans and French will soon reach a new level when Bugatti's Chiron and Hennessey's Venom F5
are put to the test.

The F5 is said to be capable of launching from a standstill to 186 mph in less than 10 seconds, eventually hitting 300 mph if given enough room to stretch its legs.
