GM developed the 6.5-litre, 397-cubic-inch engine in 1992. First versions of the motor showed increased performance over the previous 6.2-litre, advertising output at 190hp and 380 foot-pounds of torque. Eventually, the motor saw an increase in power in select applications, and output performance was advertised at 215hp and 440 foot-pounds of torque.


Built with cast-iron block and head material, the 397-cubic-inch motor was turbocharged. With a two-valve, overhead valve, the camshaft is positioned inside the cylinders. The 6.5-litre also features a larger bore x stroke dimension over the 6.2-litre, with 4.02 inches by 3.82 inches measurements.


In the beginning of its production life, the 6.5-litre diesel engine was paired with the Chevrolet/GMC heavy-duty pickup trucks and Suburbans. In 1994, the diesel motor became available to the Chevrolet Blazer/Two-door Tahoe, GMC Yukon and AM General Civilian/Military Hummers. GM continued using this engine in light-duty trucks/SUVs until 1999. In 2000, the 6.5-litre was only available in the Chevrolet/GMC 2500 and 3500 series, heavy-duty trucks. The following year, this engine was only made available to Chevrolet/GMC 3500 series trucks. After 2001, the AM General Hummer H1 series vehicles became the only consumer automobile to include the 6.5-litre turbo diesel. A marine series 6.5L engine is available for boats.
