New Certification Procedure to Verify Engine Horsepower & Torque

May 10, 2005

DETROIT — A new engine horsepower and torque certification procedure developed by the Society of Automotive Engineers (SAE) Engine Test Code committee was recently approved.The new voluntary procedure (J2723) ensures fair, accurate ratings for horsepower and torque by allowing manufacturers to certify their engines through third-party witness testing. General Motors is the first automotive manufacturer to begin using the new procedure and expects to use it for all newly rated engines in the future. The first engine to become certified under the new process is the 7.0L LS7 V-8 for the 2006 Corvette Z06. The LS7 was certified at 505 horsepower and 470 lb.-ft. of torque.
