A car with 2400 horsepower can theoretically reach speeds well over 300 mph (480 km/h), but the actual top speed is determined by more than just raw power. The key limiting factors are aerodynamic drag and tire technology. As speed doubles, the force of drag increases fourfold, requiring a massive eightfold increase in power to overcome it. This is why achieving extreme speeds becomes exponentially difficult.
Real-world examples from the hypercar world demonstrate this. The Bugatti Chiron Super Sport 300+, with around 1600 hp, achieved a verified top speed of 304 mph. The Koenigsegg Jesko Absolut is theoretically capable of over 330 mph, thanks to its 1600 hp engine and the most aerodynamically efficient body ever seen on a production car. A 2400 hp vehicle would need a similarly optimized, low-drag body and specialized tires rated for such incredible stresses.
| Vehicle / Concept | Horsepower | Claimed / Theoretical Top Speed (mph) | Key Factor |
|---|
| Bugatti Chiron Super Sport 300+ | ~1600 hp | 304 mph (Verified) | Advanced aerodynamics & powertrain |
| Koenigsegg Jesko Absolut | ~1600 hp | 330+ mph (Theoretical) | Extreme aerodynamic efficiency |
| Hennessey Venom F5 | 1817 hp | 311+ mph (Claimed) | Lightweight carbon-fiber construction |
| Bloodhound LSR (Land Speed Record car) | ~1350 hp + Jet engine | 600+ mph (Target) | Designed purely for top speed, not road use |
| 2400 hp Custom Hypercar | 2400 hp | 350+ mph (Theoretical) | Requires bespoke chassis, body, and tires |
Ultimately, for a road-legal car, a 2400 hp engine is overkill for top speed alone without a chassis and body designed from the ground up to slice through the air. The engineering challenge isn't just making the power; it's building a car that can survive using it.
