The legendary McLaren F1 set a speed record with an average of 221 mph in 1998, and then held the highest production car speed record until 2005 when the Bugatti Veyron finally beat it with an average speed of 253 mph.
Since 2005, Bugatti has been the name to beat in the high speed category.
A dude from Sweden is over it.
The Koenigsegg Agera RS achieved an average of 277.9 on a closed section of Nevada highway according to Jalopnik. While the runs are not yet official for world record book purposes, but seeing the car hit 284 in the above video is enough for us.
