A quarter-mile time is a measure of a vehicle's acceleration performance, typically used in drag racing and performance car evaluations. It measures how long it takes a vehicle to travel 1/4 mile (402.336 meters) from a standing start.
What is a quarter-mile time?
The quarter-mile time is a key performance metric for vehicles, particularly in the automotive and motorsports industries. It represents the time it takes for a vehicle to accelerate from 0 to 60 mph and then continue to cover the remaining 1/4 mile of the track.
This measurement is commonly used in drag racing and performance car evaluations because it provides a comprehensive view of a vehicle's acceleration capabilities beyond just the 0-60 mph time. A faster quarter-mile time indicates better acceleration performance.
Note: Quarter-mile times are typically measured on a dragstrip with a known distance of 1/4 mile. The exact measurement may vary slightly depending on the specific track layout.
How to calculate quarter-mile time
Calculating the quarter-mile time involves determining the time it takes for a vehicle to travel 1/4 mile from a standing start. This can be done using the following steps:
- Measure the time it takes for the vehicle to accelerate from 0 to 60 mph (t1).
- Calculate the distance covered during this acceleration phase using the formula: distance = (initial velocity + final velocity) × time / 2.
- Subtract the distance covered during the 0-60 mph phase from the total 1/4 mile distance to find the remaining distance (d2).
- Calculate the time it takes to cover the remaining distance (d2) at a constant speed (v2).
- Add the time for the 0-60 mph phase (t1) and the time for the remaining distance (t2) to get the total quarter-mile time.
This calculation provides an approximation of the quarter-mile time based on the vehicle's acceleration and top speed.
Formula used
The quarter-mile time (T) can be approximated using the following formula:
T ≈ t1 + (d2 / v2)
Where:
- t1 = Time to accelerate from 0 to 60 mph (seconds)
- d2 = Remaining distance after 0-60 mph phase (feet)
- v2 = Average speed during the remaining distance (feet per second)
This formula provides a reasonable approximation of the quarter-mile time based on the vehicle's acceleration and top speed.
Worked example
Let's calculate the approximate quarter-mile time for a vehicle with the following parameters:
- Time to accelerate from 0 to 60 mph (t1) = 5.2 seconds
- Distance covered during 0-60 mph phase (d1) = 220 feet
- Total quarter-mile distance = 1320 feet
- Remaining distance (d2) = 1320 - 220 = 1100 feet
- Average speed during remaining distance (v2) = 120 mph = 176 feet per second
Using the formula:
T ≈ 5.2 + (1100 / 176) ≈ 5.2 + 6.25 ≈ 11.45 seconds
Therefore, the approximate quarter-mile time for this vehicle is 11.45 seconds.
Comparison table
The following table compares the quarter-mile times for different vehicles:
| Vehicle | 0-60 mph Time (seconds) | Quarter-Mile Time (seconds) |
|---|---|---|
| Chevrolet Camaro SS | 3.6 | 10.8 |
| Ford Mustang GT | 3.5 | 10.5 |
| Dodge Challenger SRT Demon | 2.3 | 9.6 |

This table provides a comparison of quarter-mile times for different high-performance vehicles, showing the relationship between 0-60 mph time and quarter-mile time.
FAQ
The 0-60 mph time measures how quickly a vehicle can accelerate from a standing start to 60 miles per hour, while the quarter-mile time measures the total time to cover 1/4 mile from a standing start. The quarter-mile time provides a more comprehensive view of a vehicle's acceleration performance.
The approximation provided by this calculator is reasonably accurate for most performance vehicles. However, actual quarter-mile times may vary slightly due to factors such as tire grip, track conditions, and driver technique.
Yes, this calculator can be used for electric vehicles. Simply input the 0-60 mph time and top speed of the electric vehicle to calculate the approximate quarter-mile time.
