Notes:
When comparing 60 mph to 100 mph runs straight out, you will see that in the 0 to 100 mph that the same segment is faster. Reason for this is the momentum of the moving vehicle enhances the required time to cover that "time to speed" at a faster rate.

All times are averaged out in both directions with a minimum of six runs per car. Experienced drivers are used…no professional behind the wheel. No power shifting! Many years of testing contains more than ten cars of each model and setup. Only blacktop surfaces are used. Weather test conditions must meet the following criteria: 60 to 70 degrees & 35% to 50% humidity.

All cars are factory stock unless noted in Spec catergories. Equipment used: Vericom 2000 Pro Performance (real time systems). Driver weight between 180-200lbs. Half tank of gas and tires at normal inflation levels. No (slicks) special tires are ever used.
