Formula

Turns two timeslips into gaps that read like a race result.

Gap60 = A - B; trap gap = B - A; improvement% = gap60/A x 100

Alternative Form

Trap speed reflects power; 0-60 adds grip and launch

Explanation

0-60 rewards launch and grip while trap rewards power — together they profile both cars.

Step-by-Step Calculation

Follow each step to understand how the result is calculated from your inputs.

Step 1

Record the inputs.

0-60 — Car A:6.5 s
0-60 — Car B:5.0 s
Trap Speed — A:95 mph
Trap Speed — B:105 mph
Result: 4 inputs ready
Step 2

Apply the formula.

Gap60 = A - B; trap gap = B - A; improvement% = gap60/A x 100
Result: Primary result = 1.50 s
Step 3

Read every derived output.

0-60 Gap (A-B):1.50 s
Trap Gap (B-A):10.0 mph
0-60 Improvement:23.1 %
Result: 0-60 Gap (A-B) = 1.50 s
Final Answer
1.50

Worked Examples

See how the calculator works with different scenarios.

Scenario

Sport sedan versus coupe showdown.

Inputs

A:6.5 s, 95 mph
B:5.0 s, 105 mph

Calculation

Gap 1.5 s; trap +10 mph; 23.1% quicker

Result

B by 1.5 s and 10 mph.

Interpretation

Clear B win on launch and power both.

Understanding Your Result

Your Result: 0-60 Gap (A-B): 1.50 s

Typical range: 0.3 s is close; 1+ s is decisive.

What This Means

Measured performance gap in launch and top-end.

Why It Matters

Separates grip-limited 0-60 from power-led trap speed.

Professional Interpretation

Treat the primary result as a planning estimate, then validate on a dyno, at the track, or with logged sensor data. If measured numbers disagree by more than ~10%, re-check inputs (units are the usual culprit) before changing parts.

Recommendations

  • •Double-check units on every input before trusting the result
  • •Compare against the worked example below to sanity-check magnitude
  • •Validate with measured data (dyno, timeslip, datalog) when it matters

Learn — fuel economy, deeply

Performance comparison reads two timeslips as one gap.

1 · Where the gallon goes (energy path)

Engine heat

60–70% lost

Coolant + exhaust carry most energy away. Hybrids recover some via Atkinson cycle + regen.

Driveline

5–15% lost

Transmission, differential, accessories. CVTs and 8–10 speed autos lose less.

Aero drag

∝ v²

Doubles from 55→78 mph. Roof boxes hurt more than trunks.

Rolling + brakes

10–20%

Tires, weight, stops. Regen braking (hybrid/EV) reclaims city braking energy.

4 · Measure like a pro (the 3-tank protocol)

  1. Fill to first click at the same pump, record the odometer (Tank 0).
  2. Drive normally for 2–3 tanks; always refill to first click at the same pump.
  3. MPG = total miles ÷ total gallons across all tanks — averaging kills pump-click noise.
  4. Cross-check with the trip computer; a persistent >10% gap means the computer needs calibration — or the car needs service.
  5. Log with an OBD-II dongle for per-trip MPG if you want to isolate commute vs. highway behavior.

Practical Tips

  • •Compare same-surface, same-day runs
  • •Trap speed is the cleaner power signal
  • •Average multiple passes

Common Mistakes

Mixing units (inches with mm, psi with kPa)
Convert every input to the unit shown on its field before calculating.
Trusting a single output blindly
Cross-check with the worked example and, when it matters, a dyno or datalog.

Assumptions

This calculator makes the following assumptions to provide estimates:

Steady-state model: Formulas assume stabilized conditions; transients, heat soak and traction limits are excluded.
Standard factors: Empirical constants (BSFC, VE, drivetrain loss) use typical values — your combination may differ.

Limitations

Be aware of these limitations when using this calculator:

Estimate, not measurement: Predictions carry real-world scatter of roughly ±5–15% depending on the model.
No transient effects: Shift time, wheelspin, spool lag and heat soak are not modeled here.

Frequently Asked Questions

Answers to common questions about this calculator.

Which matters more, 0-60 or trap?
0-60 includes launch skill and grip; trap speed isolates power. Use both for a full picture.
Can I compare magazine times?
Roughly — but rollout, surface and weather differ. Same-day testing is far better.

Glossary

Technical terms used in mortgage calculations explained in plain language.

MPG
Miles per gallon. Distance travelled per gallon of fuel; higher is better. US gallon = 3.785 L.
L/100 km
Litres consumed per 100 kilometres; lower is better. Standard metric efficiency unit.
MPGe
Miles per gallon-equivalent. EV metric: miles travelled on 33.7 kWh (energy of 1 gal of gasoline).
CAFE
Corporate Average Fuel Economy — US fleet-average efficiency standard enforced by NHTSA.
Rolling resistance
Energy lost deforming tires as they roll. Low-pressure or wide tires raise it.
Aerodynamic drag
Air resistance growing with the square of speed — why highway MPG falls fast above 60 mph.
Hypermiling
Driving techniques (coasting, steady speed, anticipation) that maximise real-world MPG.
OBD-II
On-board diagnostics port. Scanners and dongles read live MPG, fuel trim and fault codes.
