Why does the 911 GT3 win?
The decisive inputs are the complete system, not peak power alone. The model applies drivetrain efficiency, launch traction, transmission shift interruption, vehicle mass, rolling resistance and speed-dependent aerodynamic drag at 120 updates per second. In this matchup, the Porsche 911 GT3 turns its 350 hp-per-tonne input into the earlier 1 km finish.
Every value above is generated under the same dry, level, equal-condition simulation. It is useful for relative comparison, not a substitute for an instrumented test of a specific car, tyre, driver, surface or weather condition.
