Performance Estimator

Rough acceleration estimate from power-to-weight.

Method

• hp/tonne = engine power ÷ (vehicle mass in tonnes) — an exact ratio, not modeled.
• 0-100 km/h and quarter-mile (400 m) times come from the work-energy theorem for a vehicle under constant wheel power: v(t) = √(2·P·t/m), assuming an 85% drivetrain efficiency and no aerodynamic drag, rolling resistance or gear-shift pauses.

Limits

This is an idealized, order-of-magnitude lower bound, not a lap or drag-strip simulation. Real cars take noticeably longer because of drag, a non-flat torque curve, tyre traction limits at launch, and time lost shifting gears.
