Bonus: Concept or Near-Production Cars Koenigsegg Jesko: 300+ (Claimed) The Koenigsegg Jesko making its debut at the 2019 Geneva Motor Show. It comes with a twin-turbo 4.0-liter V8 that’s paired with an electric motor for a combined output of 1,035 horsepower. But the car’s aerodynamic body and mega-powered electrified powertrain result in a car that’s built for speed. Unlike most of the cars on this list, McLaren wasn’t attempting to set a new top speed record with the Speedtail. The runs were part of McLaren’s testing procedures and were performed at the Kennedy Space Center runway in Florida. Still, the story about how McLaren tested the Speedtail’s top speed is bewildering, as the automaker’s test prototype called the XP2 reportedly hit 250 mph more than 30 times, claims McLaren. The McLaren Speedtail has an asterisk by its top-speed run, because it never actually made a top speed run in the same way as the other supercars on this list and because it’s not street-legal in the U.S. The Ultimate Aero TT’s top speed run is even more impressive when you hear that the vehicle doesn’t have any electronic driver aids to help keep the car pointed in a straight line. It do so thanks to a twin-turbocharged 6.3-liter V8 engine making 1,183 horsepower. The wedge-shaped supercar came out of nowhere and managed to beat the mighty Bugatti and Koenigsegg. The company made the run on a closed stretch of road in the state of Washington. On September 24, 2007, Shelby Supercars (SSC) Ultimate Aero TT set a new world record by hitting 257 mph. SSC Ultimate Aero TT: 265 mph SSCįor seventh fastest car in the world, we have to travel back a few years to 2007. Bugatti also developed a convertible version, dubbed the Grand Sport Vitesse, which still holds the record for the fastest open-top production car at 254 mph. An impressive 1,200 horsepower and a slew of aerodynamic improvements helped the Super Sport to a top speed of 268 mph, clocked at Volkswagen’s Ehra-Lessein test track. Bugatti went back to the drawing board and returned with the Veyron Super Sport. Impressive as it was, the 250-mph Veyron was soon trumped by the 256-mph SSC Ultimate Aero. The $1.7-million Veyron utilized a quad-turbocharged, W16 engine to deliver 1,001 horsepower to all four wheels. A tremendous investment of time and resources yielded the Bugatti Veyron in 2005. Unlike its upstart rivals, Bugatti benefitted from the massive cash reserves of its parent company, Volkswagen. That’s why top speed records rarely get broken.īefore Hennessey and Koenigsegg jumped into the top-speed fray, Bugatti dominated the world’s fastest category. Beyond ensuring that a car has the right amount of power and efficiently flows through the air, finding a long enough stretch of road to get a car up to 300 mph is nearly impossible. Unlike other figures that are used to differentiate vehicles from one another, like zero-to-60 mph times, cornering G-force, or quarter-mile times, setting a new top speed record is insanely difficult.
