How does 0–100 km/h compare to 0–60 mph?

0–60 mph ends at 96.56 km/h, not 100 km/h. The 0–100 km/h time is approximately 3–5% longer: t(0–100) ≈ t(0–60 mph) × 1.03–1.05.

Why does the formula over-predict 0–100 times for AWD cars?

Hale's formula is calibrated for RWD cars. AWD eliminates wheelspin and typically outperforms the prediction by 20–35%.

What is the metric equivalent of Hale's formula?

t = 6.520 × (W_kg / P_kW)^(1/3), derived by converting Hale's imperial constants to SI and adjusting for the 100 vs 96.56 km/h endpoint.

What power-to-weight ratio is needed for 0–100 km/h in under 4 seconds?

P_kW / W_kg > (6.520/4.0)³ ≈ 4.24, meaning 424 kW per 1,000 kg. AWD hypercars achieve sub-4 sec through traction as much as raw power.

What This Calculator Does

The 0–100 km/h calculator predicts acceleration time using the metric-adapted Hale formula, the same empirical approach used by automotive journalists worldwide. Unlike 0–60 mph (which ends at 96.56 km/h), 0–100 km/h is the global standard — used in all European, Asian, and Australian automotive testing. Enter your vehicle's kerb weight in kg and power in kW (or hp), and compare the result against the European and JDM reference table below. The 0–100 metric time is approximately 3–5% longer than the equivalent 0–60 mph time because of the extra speed band.

It combines Vehicle Kerb Weight, Wheel Power, Flywheel Power (optional), Drivetrain to estimate 0–100 km/h Time, Equivalent 0–60 mph Time, Power-to-Weight.

Formula & Method

Metric Hale formula:

t_{0\text{-}100} = 6.520 \times \left(\frac{W_{kg}}{P_{kW}}\right)^{1/3}

where

W_{kg}

is kerb weight in kilograms and

P_{kW}

is wheel power in kilowatts. Wheel power from flywheel:

P_{wheel} \approx P_{flywheel} \times (1 - \eta_{drivetrain})

where typical drivetrain loss

\eta \approx 0.15

–

0.18

for RWD. Relationship to 0–60 mph:

t_{0\text{-}100\,km/h} \approx t_{0\text{-}60\,mph} \times 1.035

(same power, same car, identical conditions).

Notation used in the formulas: $R$ = 0–100 km/h Time; $x_{1}$ = Vehicle Kerb Weight; $x_{2}$ = Wheel Power; $x_{3}$ = Flywheel Power (optional); $x_{4}$ = Drivetrain.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Worked Examples

Hot hatch — 1,350 kg, 180 kW (241 hp) at wheels

t = 6.520 × (1350 / 180)^(1/3) = 6.520 × (7.50)^(1/3) = 6.520 × 1.957 = 12.76 sec ← predicted Comparison: A Volkswagen Golf R (1,515 kg, ~220 kW flywheel, ~185 kW at wheels) t = 6.520 × (1515/185)^(1/3) = 6.520 × (8.19)^(1/3) = 6.520 × 2.014 = 13.1 sec VW claims 4.7 sec with AWD launch control — real-world traction dramatically beats the formula prediction for AWD cars. Note: The Hale formula assumes RWD with traction-limited launch. AWD cars often outperform it by 20–30%.

Sports car — 1,580 kg, 350 kW (469 hp) at wheels

t = 6.520 × (1580 / 350)^(1/3) = 6.520 × (4.514)^(1/3) = 6.520 × 1.651 = 10.76 sec ← Hale prediction Equivalent 0–60 mph ≈ 10.76 / 1.035 = 10.4 sec Real-world deviation: A BMW M3 Competition (1,730 kg, 375 kW flywheel, ~315 kW at wheels) Hale: 6.520 × (1730/315)^(1/3) = 6.520 × 1.762 = 11.5 sec Claimed: 3.9 sec (AWD xDrive). Hale assumes RWD, poor launch — AWD with launch control cuts this by ~65%.

Common Mistakes

Using flywheel power instead of wheel power — deduct 15–18% for RWD, 20–22% for AWD (higher mechanical drag). A 200 kW flywheel car may deliver only 165–170 kW at the wheels.
Expecting formula accuracy for AWD cars — AWD with launch control bypasses traction limitations and typically outperforms the Hale prediction by 20–35%. The formula is calibrated for RWD with a competent launch.
Ignoring altitude effects — high-altitude testing (Denver: 1,600 m) reduces air density and engine power by ~15%, lengthening 0–100 times by a similar margin for naturally aspirated engines.
Comparing claimed times vs road-test times — manufacturers test on optimal surfaces (smooth tarmac, 20°C, sea level) with full launch control. Road tests in different conditions often show 0.3–0.5 sec slower times.
Confusing 0–100 km/h with 0–100 mph — 0–100 mph is a separate and much more demanding test; don't mix the two in comparisons.
