The chase for 300 miles per hour is the ultimate engineering challenge in the automotive world. It demands extraordinary power, meticulous aerodynamics, tire technology that can withstand immense forces, and a driver willing to risk everything. Only a handful of production cars have ever exceeded 300 miles per hour, and the debate over which one truly owns that speed is fiercely contested.
The Bugatti Chiron Super Sport 300+ holds the official production car speed record, having achieved 304.773 miles per hour in 2019. The Koenigsegg Jesko Absolut is designed to exceed that figure, though it has yet to make an official record attempt. Both cars represent the absolute pinnacle of engineering. Both are limited in production, astronomical in price, and brutal in performance.
This article compares the Bugatti Chiron and the Koenigsegg Jesko across engineering, performance, aerodynamics, and speed record claims to determine who really owns the 300 miles per hour crown.
The Contenders: Two Different Approaches to Speed
Bugatti Chiron Super Sport 300+
The Bugatti Chiron is the successor to the Veyron, the car that first broke the 250 miles per hour barrier. The Super Sport 300+ is a limited edition variant designed specifically to chase the 300 miles per hour record. It uses an 8.0 liter quad-turbocharged W16 engine producing 1,578 horsepower. The car features a longer tail, revised aerodynamics, and a higher final drive ratio to achieve its record speed.
Koenigsegg Jesko Absolut
The Koenigsegg Jesko is named after the company’s founder, Jesko von Koenigsegg. The Absolut variant is designed for top speed, with a lower drag coefficient than any other Koenigsegg. It uses a 5.0 liter twin-turbocharged V8 engine producing 1,600 horsepower on standard fuel and up to 1,600 horsepower on E85. The car features a revolutionary nine-speed multi-clutch transmission and active aerodynamics.
Powertrain and Engineering
Bugatti Chiron Super Sport 300+
The Chiron’s W16 engine is one of the most complex production engines ever built. The W configuration combines two narrow-angle V8 engines sharing a common crankshaft. The engine features four turbochargers arranged in a staged configuration.
- Displacement: 8.0 liters
- Configuration: Quad-turbo W16
- Horsepower: 1,578 hp
- Torque: 1,180 lb-ft
- Transmission: 7-speed dual-clutch
- Drive: All-wheel drive
- Weight: Approximately 1,975 kg
Koenigsegg Jesko Absolut
The Jesko’s V8 engine is a development of the unit that powered the Agera. It features a flat-plane crank, twin-turbochargers, and a revolutionary Light Speed Transmission (LST). The LST has nine forward gears and can shift between any gear almost instantly.
- Displacement: 5.0 liters
- Configuration: Twin-turbo V8
- Horsepower: 1,600 hp (E85)
- Torque: 1,106 lb-ft (E85)
- Transmission: 9-speed Light Speed Transmission
- Drive: Rear-wheel drive
- Weight: Approximately 1,420 kg dry
Engineering Verdict
The Chiron’s W16 is an extraordinary piece of engineering, but it is heavy and complex. The Jesko’s V8 is lighter, simpler, and more powerful. The Jesko also features a more advanced transmission. The Koenigsegg has the engineering advantage.
Aerodynamics and Design
Bugatti Chiron Super Sport 300+
The Super Sport 300+ features a longer tail than the standard Chiron, reducing drag and improving high-speed stability. The car has a drag coefficient of approximately 0.36. The active rear wing and front splitter adjust to balance downforce and drag.
The design is elegant and aerodynamic, with a long, flowing tail and a distinctive paint scheme that transitions from dark to light.
Koenigsegg Jesko Absolut
The Jesko Absolut is designed for minimal drag. The car has a drag coefficient of just 0.278, one of the lowest of any production car. The Absolut deletes the large rear wing of the standard Jesko, replacing it with smaller fins and a more streamlined tail.
The design is more aggressive than the Bugatti’s, with sharp lines and dramatic air intakes.
Aerodynamics Verdict
The Jesko Absolut has a significantly lower drag coefficient than the Chiron Super Sport 300+. The Koenigsegg is more aerodynamically efficient, which should allow it to achieve a higher top speed with less power.
Performance and Speed Records
The Official Record
The Bugatti Chiron Super Sport 300+ holds the official Guinness World Record for the fastest production car. On August 2, 2019, a pre-production prototype driven by Andy Wallace achieved a two-way average speed of 304.773 miles per hour at the Ehra-Lessien test track in Germany. The production version is limited to 273 miles per hour to protect the tires, but the car is capable of exceeding 300 miles per hour.
The Koenigsegg Claim
Koenigsegg claims the Jesko Absolut is capable of exceeding 330 miles per hour. The company has not yet made an official record attempt. The Jesko’s 1,600 horsepower, low drag coefficient, and advanced transmission should theoretically allow it to surpass the Bugatti’s record. However, theory and practice are not the same.
The Record Verdict
The Bugatti holds the official record. It has been independently verified. The Koenigsegg is theoretically faster, but until it makes a verified attempt, the Chiron remains the king.
Production and Rarity
Bugatti Chiron Super Sport 300+
Bugatti built 30 units of the Super Sport 300+. Each car is pre-sold to collectors. The price was approximately $3.9 million.
Koenigsegg Jesko Absolut
Koenigsegg is building 125 units of the Jesko, including both the Absolut and the track-focused Jesko Attack. Production is limited, and all units are pre-sold. The price is approximately $3.0 million.
Rarity Verdict
Both cars are extremely rare. The Chiron Super Sport 300+ is rarer, with only 30 units built. The Jesko Absolut is more accessible, but still limited.
Driving Experience
Bugatti Chiron Super Sport 300+
The Chiron is designed for high-speed stability. At 200 miles per hour, the car feels planted and secure. The ride is surprisingly comfortable, and the cabin is quiet. The car is not a track weapon; it is a grand tourer designed to cover vast distances at incredible speeds.
Koenigsegg Jesko Absolut
The Jesko is designed for extreme performance. The Light Speed Transmission provides instant shifts, and the active aerodynamics keep the car stable at high speeds. The ride is firmer than the Bugatti’s, and the cabin is louder. The Jesko is a more intense experience.
Driving Verdict
The Chiron is the more refined car, designed for effortless speed. The Jesko is the more raw and focused car, designed for the driver who wants to be fully engaged.
The 300mph Club
The 300 miles per hour club includes only a handful of production cars:
- Bugatti Chiron Super Sport 300+: 304.773 mph (verified)
- SSC Tuatara: Claimed 282.9 mph (disputed)
- Hennessey Venom F5: Claimed 311 mph (unverified)
- Koenigsegg Jesko Absolut: Claimed 330+ mph (unverified)
The Chiron is the only car with an independently verified production car record.
Which One Owns 300mph?
The answer depends on how you define the question.
If you consider official, independently verified records, the Bugatti Chiron Super Sport 300+ owns 300 miles per hour. It has the Guinness World Record. It is the only car that has proven its capability.
If you consider theoretical capability, the Koenigsegg Jesko Absolut is the more promising car. Its lower drag coefficient, higher power output, and advanced transmission suggest it could exceed the Bugatti’s record.
Until Koenigsegg makes a verified attempt, the crown belongs to Bugatti.
