The fastest car ever built is the ThrustSSC, a jet-powered vehicle that achieved a land speed record of 763 mph (1,228 km/h) in 1997, making it the first car to break the sound barrier. For production cars, the Bugatti Chiron Super Sport 300+ holds the record with a verified top speed of 304.773 mph (490.484 km/h) in 2019. These speeds are measured under controlled conditions, such as on dry lake beds or specialized tracks, and involve factors like aerodynamics, powertrain efficiency, and safety protocols.
Top speed records vary between purpose-built land speed vehicles and street-legal production models. Land speed cars like the ThrustSSC are designed for extreme velocity with minimal drag, while production cars balance speed with drivability and regulations. Achieving these speeds requires immense power; for instance, the ThrustSSC used twin Rolls-Royce jet engines producing over 100,000 horsepower.

When considering "fastest," it's important to distinguish between verified records and theoretical claims. Authority sources like Guinness World Records and Fédération Internationale de l'Automobile (FIA) provide official certifications. For everyday drivers, top speed is less critical than acceleration (e.g., 0-60 mph times) and handling, but these records push automotive innovation forward.

Oh man, the ThrustSSC is the absolute king—it hit 763 mph back in '97! That's faster than some planes. For cars you can actually buy, Bugatti's Chiron is insane at over 300 mph. I love geeking out over this stuff; it's all about raw power and slick design. But honestly, most of us will never need that speed—it's just cool to dream about while stuck in traffic.
