The fastest Hummer car ever made is the 2003  Lingenfelter  H2   at 6.30 seconds.
While the Hummer 0 to 60 MPH times and quarter mile data detailed here have been pulled from a number of credible sources, there are also many different factors that can impact speed.
How fast a Hummer accelerates depends on the vehicle's tires, whether the test is conducted inside or outside, the weather conditions at the time, the wind velocity for or against the car, and the driver's ability. For this reason, different sources can test the same car and clock different times.
