Bugatti and SSC have been fighting for the production car speed record since the 2000s. Bugatti set its first record with Veyron in 2005, when the first iteration of the supercar hit 253.8 mph. SSC stole their record in 2007 with the Ultimate Aero TT, improving the benchmark slightly at 256.1 mph. Bugatti recaptured its record in 2010 with the Veyron Super Sport at 267.8 mph. The record is currently being held by the Koenigsegg Agera RS at 277.8 mph, but Bugatti set an unofficial record in 2019 with the Chiron Super Sport 300+, the first production model that reached beyond 300 mph with a 304.7-mph benchmark.
