2020 Bugatti Chiron Automatic (AM-S7) vs 2025 Tesla Model S: Modelled Straight-Line Test

DragGap comparison data

The table below summarises the key modelled figures from DragGap's simulation. Each value is an estimated output from a consistent simulation model, not a measured result.

| Metric | 2020 Bugatti Chiron Automatic (AM-S7) | 2025 Tesla Model S | |---|---:|---:| | Body | Coupe | Sedan | | Output | 1641 kW / 2200 hp | 1641 kW / 2200 hp | | Mass | 1419 kg | 2178 kg | | Drivetrain | All-wheel drive | All-wheel drive | | 0-60 mph | 2.03 s | 1.91 s | | 0-100 km/h | 2.10 s | 1.97 s | | 1/4 mile | 8.16 s | 8.09 s | | 1 km | 13.71 s | 13.24 s | | Top speed | 430.8 km/h | 497.0 km/h |

Two ways to deploy the same projected output

The most striking thing about this matchup is that DragGap models both cars with the same enormous peak output: 1641 kW / 2200 hp, and both are all-wheel drive. Yet the two cars take very different routes to it. The 2020 Bugatti Chiron Automatic (AM-S7) is a lightweight coupe at 1419 kg, while the 2025 Tesla Model S is a far heavier 2178 kg sedan.

That weight difference normally would tell most of the story, but the simulation flips the expected script. Despite carrying roughly 759 kg more, the Tesla is the projected winner in DragGap's model.

Remember that every one of these figures is an estimated output from DragGap's model. They are useful for comparison, not measured real-world performance.

Straight-line pace: the simulated race

The modelled 0-100 km/h times are close, with the 2025 Tesla Model S at 1.97 s against 2.10 s for the 2020 Bugatti Chiron Automatic (AM-S7). Over the quarter mile the Tesla records a simulated 8.09 s versus 8.16 s for the Bugatti.

The margin grows over a full kilometre, where the Tesla's modelled 13.24 s beats the Bugatti's 13.71 s. Top-speed projections also favour the Tesla sharply, at 497.0 km/h against 430.8 km/h for the Bugatti.

In the modelled race, the Tesla Model S is recorded as the winner with a finish gap of roughly 49.7 metres and a victory margin of about 0.46 seconds. As with all numbers here, these are simulated projections, not measured results.

Why the heavier car wins in the simulation

At equal projected power and drivetrain, the Tesla's advantage in DragGap's model comes down to how the output is delivered and sustained. The Model S is modelled with a higher top-speed projection and keeps pulling for longer as speeds rise, which narrows and then reverses the gap that the Bugatti's lighter mass would otherwise open early.

Both cars are marked as modified in the simulation, so DragGap treats them as highly tuned projections rather than stock production examples. That is worth keeping in mind: these figures describe the specific modelled configurations, not the cars as they leave the factory.

A straight-line model also isolates raw output and gearing while leaving real-world launch physics and tyre behaviour to be inferred, which is exactly why these results should be read as modelled estimates.

What the numbers really tell you

If the priority is the fastest projected straight-line result, the 2025 Tesla Model S is the clear pick in this simulation, edging the Bugatti from a standing start and stretching away at higher speeds.

If instead you value the engineering spectacle of an internal-combustion hypercar that weighs barely 1400 kg and still projects 2200 hp, the 2020 Bugatti Chiron Automatic (AM-S7) is the more dramatic machine.

Both answers are valid depending on what matters to you. The simulation gives a consistent comparison, but your priorities decide which car is the better pick.
