Question 1

What is a good 0-60 mph time?

Accepted Answer

Under 6 seconds is considered fast for regular cars, under 4 seconds is sports car territory, and under 3 seconds is supercar/hypercar level. Average family sedans typically achieve 7-9 seconds.

Question 2

Why is 0-60 mph used instead of 0-100 km/h?

Accepted Answer

0-60 mph is the standard in the US and UK, while 0-100 km/h is used in metric countries. 60 mph equals about 97 km/h, so the times are very similar but not identical.

Question 3

Does weight or power matter more for acceleration?

Accepted Answer

Both matter equally in the power-to-weight ratio. Removing 100 lbs has the same effect as adding proportional horsepower. Light cars with moderate power can match heavy cars with high power.

Question 4

How does altitude affect acceleration?

Accepted Answer

Naturally aspirated engines lose about 3% power per 1,000 feet of altitude due to thinner air. Turbocharged engines are less affected as they compress intake air.
