Introduction

applicable laws and regulations.
Note: In the event of conflict between the
English and domestic language, the English language shall take
precedence.
Purpose. The purpose of this test is for a
vehicle performance assessment relative to the vehicle's tendency
to power hop in either the forward or reverse direction. It can
also be used to gather data for use in computer models and/or
Hardware in Loop (HIL) simulations to evaluate and correlate power
hop behavior on high horsepower vehicles. Finally, it can be used
to evaluate the performance of vehicle components (axles and
propeller (prop) shafts, etc.) after being subjected to severe
loads resulting from induced power hop.
Applicability. Passenger cars and light
trucks.
Remarks. This test is typically run by GM Test
Operations Group and the Driveline Development Group. It is used
for development of the drivetrain and suspension. This system
includes but, is not limited to, driveshaft, half shafts, axles,
sub frame and suspension bushings, dampers, tires, etc.
