November 4 was just another Saturday for most, but it was a milestone for Koenigsegg Automotive. That day, their Koenigsegg Agera RS automobile broke five speed records, earning it the title of being the world’s fastest street-legal car.

KOENIGSEGG AGERA RS BREAKS SPEED RECORDS

Niklas Lilja, one of the company’s production drivers, drove the Agera RS as it beat five previous world records. The Guinness World Records hadn’t verified Lilja’s run on Saturday, but Koenigsegg nevertheless posted about their accomplishments:

The Agera RS drove on a closed road stretching from Pahrump, Nevada, to Las Vegas, maintaining an average speed of 277.9 mph, which Koenigsegg boasts is the highest top speed for a production car. Notably, the the Bugatti Chiron previously held this record at 267.81mph.

The second victory was finishing a 0 to 400 km/h run in 33.29 seconds, besting the prior record of 36.44 seconds. Notably, the Agera RS itself held the previous record, which was attained last month. Koenigsegg also scored the records for the highest average speeds for “a flying kilometer on a public road,” “a flying mile on a public road,” and the highest overall speed on a public road. These records are respectively at 445.54 km/h (276.9 mph), 444.66 km/h (276.36 mph), and 457.49 km/h (284.55 mph).

Faster cars do exist, but the Agera RS can now claim to be the world’s fastest street-legal car. Of course, the Agera RS will someday be in danger of loosing these crowns to its competitors.  Hennessey Special Vehicles’ forthcoming Venom F5 is aiming to reach 300mph, and other automobile engineers will surely continue to push the envelope further. However, for now, the Sweden-based Koenigsegg crew can enjoy their victory lap.

Two videos are available for those who wish to sample the Agera RS’s run, showcasing it obtaining the record average speed and the swiftest acceleration from 0 to 400 km/h.
