The supercar world has always been about one thing — pushing limits. From design to performance, engineers and automakers compete to redefine what’s possible on four wheels. And in 2025, the competition has reached a whole new level.
Here’s a look at five record-breaking supercars that have crossed — or are built to cross — the 400 km/h mark, setting new benchmarks for speed, technology, and innovation.
1. Koenigsegg Jesko Absolut – Estimated 499 km/h:
When it comes to chasing top-speed records, Koenigsegg is always at the forefront. The Jesko Absolut is the Swedish automaker’s most ambitious project yet — and possibly the last word in combustion-engine speed.
With a twin-turbo 5.0-liter V8 engine producing 1,600 horsepower, a slippery 0.278 Cd drag coefficient, and cutting-edge aerodynamics, simulations show it could hit 499 km/h.
In August 2025, Koenigsegg set a world record for the 0–400–0 km/h run, completing it in just 25.21 seconds. While an official top-speed run is pending, experts believe the Jesko Absolut could soon dethrone every other car on the planet.
2. YangWang U9 Xtreme – 496 km/h
The YangWang U9 Xtreme from China’s BYD subsidiary stunned the world by reaching 496.22 km/h at Germany’s ATP Automotive Testing track.
This all-electric hypercar runs on four electric motors generating a combined 3,000 hp and a 1,200-volt Blade Battery system.
Limited to only 30 units, the U9 Xtreme is a clear sign that electric vehicles are no longer about efficiency — they’re about dominance. With incredible acceleration and futuristic design, it’s rewriting what EVs can achieve.
3. SSC Tuatara – 475 km/h
The SSC Tuatara, from the American automaker Shelby SuperCars, remains a name synonymous with controversy and achievement.
After much debate about its earlier top-speed claims, SSC proved its might with a verified run of 474.8 km/h at Florida’s Kennedy Space Center.
Powered by a 5.9-liter twin-turbo V8 producing 1,750 hp on E85 fuel, the Tuatara combines raw muscle with aerospace-grade aerodynamics — making it one of the fastest production cars ever tested.
4. Bugatti Chiron Super Sport 300+ – 490 km/h
Bugatti has long defined luxury and speed, and the Chiron Super Sport 300+ proved that legacy yet again. In 2019, it became the first production car to break 300 mph (490.484 km/h).
Its 8.0-liter quad-turbo W16 engine produces 1,577 hp, sending power through an advanced all-wheel-drive system.
Although production models are electronically limited to 440 km/h, the Chiron Super Sport 300+ remains an engineering marvel — a perfect fusion of speed, luxury, and stability.
5. Rimac Nevera R – 430 km/h
The Rimac Nevera R is proof that electric cars are not just the future — they’re the present.
With four independent electric motors delivering over 2,100 hp, the Nevera R achieves a top speed of 430 km/h and record-breaking acceleration numbers.
It uses a 120 kWh battery, carbon-fiber monocoque, and enhanced aerodynamics, including a larger diffuser and fixed rear wing. Beyond speed, it offers incredible control and instant torque — a combination unmatched by traditional supercars.
The Future of Speed: Engineering Beyond Limits
Crossing 400 km/h isn’t just about power — it’s about mastering aerodynamics, stability, and innovation. These five machines are not just cars; they’re engineering masterpieces pushing the boundaries of what’s humanly and mechanically possible.
From Koenigsegg’s mechanical precision to Rimac’s electric brilliance, 2025 proves that the pursuit of speed is far from over — it’s evolving faster than ever.The race to break speed barriers has always defined the supercar world, and in 2025, a handful of machines stand out for pushing beyond 400 km/h. These cars are marvels of engineering, blending extreme power with cutting-edge aerodynamics. Here are five record-breaking supercars that have crossed—or are capable of crossing—the 400 km/h milestone.
FAQs: 5 Supercars That Can Cross 400 km/h
1. Which car is currently the fastest in the world in 2025?
As of 2025, the Koenigsegg Jesko Absolut is considered the fastest car in the world, with a theoretical top speed of 499 km/h. Although not officially tested at that speed yet, its engineering and aerodynamics make it the strongest contender.
2. Which electric car is the fastest in the world?
The YangWang U9 Xtreme and Rimac Nevera R are among the fastest electric cars in the world. The U9 Xtreme recently hit 496.22 km/h, proving that EVs can now compete directly with traditional hypercars.
3. Has any car really crossed 400 km/h in real-world testing?
Yes, several cars have officially crossed the 400 km/h mark, including the Bugatti Chiron Super Sport 300+ (490.484 km/h) and the SSC Tuatara (474.8 km/h). These runs were verified at certified testing tracks.
4. Which car has the most horsepower among these supercars?
The YangWang U9 Xtreme leads in raw power with 3,000 hp, followed by the Rimac Nevera R at 2,100 hp and the SSC Tuatara at 1,750 hp. These hypercars are engineering marvels built purely for performance.
5. Are any of these 400 km/h supercars road legal?
Yes, cars like the Rimac Nevera R, Bugatti Chiron Super Sport 300+, and Koenigsegg Jesko Absolut are road-legal, though most are produced in extremely limited numbers and come with strict driving and safety conditions.
