Ever since Bugatti unveiled the Chiron, we’ve been anxiously waiting for a new top speed world record for production cars from the French automaker. But, we didn’t get it. Instead, Bugatti set a new record for accelerating from 0 to 400 kph and coming back to a stop, achieving it in 41.96 seconds. Pretty impressive, huh? Well, it was for a little more than a month, because Koenigsegg just smashed that record by a whopping five seconds. Specifically, an Agera RS supercar was driven by Niklas Lilja to 400 kph (248.5 mph) from a standing start and then back to a full stop in only 36.44 clicks.
