Source: General Motors.  * Preliminary, pending certification. A new voluntary power and torque certification procedure developed by the SAE Engine Test Code committee was approved March 31, 2005 . This procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through 3rd-party witness testing. GM expects to use this procedure for all newly rated engines in the future.
