1. What is Quarter Mile Time?

Definition: Quarter mile time measures how quickly a vehicle can cover a quarter-mile (1,320 feet) distance from a standing start.

Purpose: It's the standard measurement used in drag racing to evaluate a vehicle's acceleration and performance.

2. Understanding Quarter Mile Times

Typical quarter mile times vary by vehicle type:

• Production cars: 12-16 seconds
• Sports cars: 10-12 seconds
• Supercars: 9-10 seconds
• Dragsters: Under 5 seconds

Explanation: Faster times indicate better acceleration. Times are typically measured with professional timing equipment at drag strips.

3. Importance of Quarter Mile Time

Details: Quarter mile time is important because:

• It measures a vehicle's acceleration performance
• It's a standard benchmark for comparing vehicles
• It helps evaluate modifications and tuning
• It's used in professional drag racing competitions

4. Factors Affecting Quarter Mile Time

Key Factors:

• Engine power and torque
• Vehicle weight
• Traction and tire grip
• Aerodynamics
• Driver skill and reaction time
• Weather conditions (temperature, humidity)
• Track surface condition

5. Frequently Asked Questions (FAQ)

Q1: What's considered a good quarter mile time?
A: For street-legal production cars, anything under 14 seconds is good, under 12 is excellent, and under 10 is exceptional.

Q2: How is quarter mile time measured?
A: Professional timing systems use light beams or sensors at the start and finish lines to precisely measure elapsed time.

Q3: What's the fastest quarter mile time ever recorded?
A: As of 2023, the record is 3.659 seconds by a Top Fuel dragster (NHRA).

Q4: Does quarter mile time measure top speed?
A: No, it measures acceleration over a fixed distance. However, trap speed (speed at finish line) is often recorded alongside ET.

Q5: Can I measure quarter mile time on public roads?
A: No, this is dangerous and illegal. Quarter mile times should only be measured at authorized drag strips or racing facilities.
