100th Engine to Receive SAE Horsepower Certification - 2009 Corvette ZR1

    WARRENDALE, Pa., May 13 /PRNewswire-USNewswire/ -- The LS9 engine in
General Motor's (GM) 2009 Chevrolet Corvette ZR1 holds the distinction of
being the 100th engine certified through SAE International's Engine Power
Test Code - Engine Power and Torque Certification (J1349).

The 2009 Corvette ZR1 engine is certified at 638 hp at 6,500 rpm, with
604 lb-ft torque at 3,800 rpm.

Engine certification is based on a series of self-certification tests
conducted by the manufacturer that are witnessed and verified by an
SAE-qualified observer. The procedure for certification is outlined in
SAE's standard J2723; the actual horsepower testing procedure is described
in J1349.

Although engine manufacturers are free to cite power and torque figures
derived from testing conducted outside the scope of the SAE standards, only
those that strictly follow all of the SAE procedures can claim to be "SAE
J1349 Certified Power."

In addition to GM's Corvette ZR1, other GM engines as well as those
from Ford and Chrysler make up the first 100 to have been certified.

Another GM engine - the LS7 used in the 2006 Corvette Z06 - was the
first engine to be certified under this SAE program.
