1) Bugatti Veyron 16.4 Super Sport — 267.8 miles per hour (official)
Reigning as the top-speed king for nearly three years, the Bugatti Veyron 16.4 Super Sport recently lost its crown because of a technicality. Guinness World Records originally bestowed the title of Fastest Production Car on the 1,200-horsepower Veyron Super Sport after it recorded a two-way average speed of 267.8 miles per hour at the Volkswagen proving grounds near Wolfsburg, Germany, on June 26, 2010. Guinness has since withdrawn the title after if learned customers’ cars were limited to 257.9 miles per hour, calling the limiter a “modification”; Bugatti calls it a safety device.
2) Hennessey Venom GT — 265.7 miles per hour (unofficial)
All too happy to see the Veyron fall, Texas-based-tuner-turned-manufacturer Hennessey says it Venom GT, based heavily on the Lotus Exige, is the new speed king, reaching 265.7 miles per hour in two miles, two fewer miles compared to the Veyron’s top-speed run. It accomplished this feat on February 9, 2013, at the Naval Air Station Lemoore in Lemoore, California, and it has a video to prove it. With Hennessey claiming its Venom GT produces 1,244 horsepower and weighs only 2,743 pounds, we have no reason to believe it isn’t true.
3) Shelby Supercars (SSC) Ultimate Aero Twin Turbo — 256.1 miles per hour (official)
Despite what many people will say about SSC’s build quality (or lack thereof), it was able to set a land-speed record for a production car with an average two-way run of 256.1 miles per hour in West Richland, Washington, on September 13, 2007.
4) Bugatti Veyron 16.4 Grand Sport Vitesse — 254.0 miles per hour (official)
With the Veyron coupe no longer in production and officially dethroned by Guinness, Bugatti released the Super Sport’s open-top twin on the Ehra-Lessien test track with Chinese racecar driver Anthony Liu at the wheel. Together, they were able to set a new world record for a roadster of 254.0 miles per
5) Bugatti Veyron 16.4 — 253.8 miles per hour (unofficial)
Bugatti set the whole world into a top-speed tizzy when it claimed that it averaged 253.8 miles per hour on April 19, 2005, with its then-new million-dollar supercar, the Bugatti Veyron 16.4. Bugatti was looking to become the world’s fastest production car, even preparing the car aerodynamically for the task with a Top Speed mode that shut a pair of diffuser flaps in the front and aligned the rear spoiler with the chassis.
6) Koenigsegg CCR — 240.1 miles per hour (official)
We know; we know. How is the 806-horsepower Koenigsegg CCR on our list when the 1,140-horsepower Koenigsegg Agera R is not? While it is true that the latter would handily outgun the former, Koenigsegg only speculates that the Agera R has a top speed of—wait for it—273 miles per hour. On the other hand, it has proved that the Koenigsegg CCR is capable of 240.1 miles per hour, taking the title from the McLaren F1 on the Nardò Ring on February 28, 2005.
7) McLaren F1 — 240.1 miles per hour (official)
Jonathan Palmer reportedly drove the F1 prototype XP3 around Italy’s Nardo test track at 231 mph, the production units’ limited top speed, but on March 31, 1998, racecar driver Andy Wallace piloted the delimited McLaren prototype XP5 to an average of 240.1 miles per hour at Volkswagen’s Ehra-Lessien test track. It still holds the crown for the world’s fastest production car with a naturally aspirated engine.
8) Aston Martin One-77 — 220.0 miles per hour (unofficial)
Aston Martin said one of the 77 One-77s achieved a top speed of 220.0 miles per hour during testing, setting a new record for an Aston Martin car.
9) Jaguar XJ220 — 217.1 miles per hour (official)
With Martin Brundle at the wheel, the Jaguar XJ220 set a new world record of 212.3 mph at Italy’s Nardò test track. After engineers removed the catalytic converters and raised the engine’s revolutions limit, it was able to reach 217.1 miles per hour.
10) Bugatti EB110 GT — 212.5 miles per hour (official)
Before Volkswagen purchased Bugatti, the revived nameplate was looking for a way to revive its stature in the automotive community. It started on the right foot: a supercar utilizing carbon fiber for its tub chassis, aluminum for its body panels, and a 3.5-liter, quad-turbocharged V-12. On May 23, 1992, the EB110 GT mule C7, with detached mirrors and Jean Philippe Vittecoq at the helm, recorded 212.5 mph at the Nardò test track.
