learn.whatIsHeading
Calculates acceleration time from 0-60 mph based on power-to-weight ratio and traction. Indicates vehicle performance.
Trin-for-trin guide
- 1Power-to-weight ratio (HP ÷ weight in lbs)
- 2Estimate from published data or calculate from torque curve
- 3Account for launch losses (1-3 seconds)
- 4Consider gearing, traction, and aerodynamic drag
Løste eksempler
Input
Accel 0-60 in 8 sec
Resultat
7.5 m/s^2
Almindelige fejl at undgå
- ✕Comparing 0-60 times in different conditions (dry vs. wet, altitude)
- ✕Not accounting for launch technique (affects traction)
Ofte stillede spørgsmål
What power-to-weight ratio do I need for quick acceleration?
10+ HP/1000 lbs: quick; 6-10 HP/1000: normal; <6 HP/1000: slow.
Why do EVs accelerate so fast from 0?
Instant maximum torque; ICE engines ramp torque; EVs achieve peak torque at 0 RPM.
