Horsepower ÷ weight = a rough 0-60 estimate. How fast is your ride?
A common estimate is: 0-60 time ≈ (weight/HP)^0.75 × a tuning constant. This empirical formula accounts for the diminishing returns of additional power — doubling HP doesn't halve your 0-60 time because of tire grip, aerodynamics, and drivetrain losses.
Traction (AWD vs RWD vs FWD), tire compound, transmission type (DCT shifts faster than manual), altitude (less air = less power), temperature, and launch technique all affect 0-60 times. A 500 HP RWD car on cold tires may be slower than a 400 HP AWD car with launch control.

0-60 time: 5.2 s
With 300 HP and 3,500 lbs (11.7 lb/HP), the estimated 0-60 time is 5.2 seconds. This is an empirical approximation — real-world results vary with traction, gearing, and drivetrain losses.
