Over the past few weeks the hypercar giants have been tussling for attention. Firstly the Bugatti Chiron claimed a world record for a test they invented in the Chiron by going from 0-249-0mph in just 42 seconds. Koenigsegg came to spoil Bugatti’s party just weeks later with the Agera RS, taking just 36.44 seconds to achieve the same test. Hennessy, not wanting to feel left out, announced the new Venom F5 which it claims could travel in excess of 300mph.

Bugatti and Hennessy are both taking their flagship vehicles (Chiron and Venom F5) out next year to have a go at the world record for the top speed. Ahead of that however, Koenigsegg has sent a strong message to both car companies over the weekend with the Agera RS. On a closed stretch of the Nevada highway the Agera RS hit 285mph, wth an average speed of 277.9mph after the two-way average was taken. Previously the world record was held by the Bugatti Veyron Super Sport which clocked 269.86mph in 2010.
