by James Rutter

In 1994, Chevy sold a 6.5-liter V-8 diesel as an optional engine for its 2500 line of full-size three-quarter ton trucks. Buyers could purchase the light-duty 2500 in rear-wheel or four-wheel drive in a regular cab with an 8-foot bed or an extended cab with a 6.5-foot bed. Chevy offered rear- and four-wheel drive heavy-duty versions of the 2500 with a regular or extended cab and an 8-foot bed.


In 1994, Chevy offered two 6.5-liter displacement diesel V-8 engines for its 2500 trucks, a turbocharged and naturally aspirated version. The naturally aspirated 6.5-liter V-8 produced 155 horsepower and 275 foot-pounds of torque. Chevy's turbocharged V-8 generated 190 horsepower and 385 foot-pounds of torque. All models of the 1994 2500 trucks came with a standard five-speed manual transmission that buyers could upgrade to a four-speed automatic with overdrive.


Fuel economy for these trucks depended on the engine, transmission and drive configuration. A rear-wheel drive non-turbo delivered an estimated 17 mpg city and 22 mpg highway with the manual transmission and 15 mpg city and 20 mpg highway with the automatic transmission.

Four-wheel drive models with the naturally aspirated engine rated 15 mpg highway and 20 mpg city with the manual transmission and 15 mpg city and 18 mpg highway with the automatic transmission. The rear-wheel drive turbocharged delivered an estimated 15 mpg city and 19 mpg highway with the automatic transmission; four-wheel drive turbocharged models rated 14 mpg city and 17 mpg highway with the automatic.

The rear-wheel drive regular cab light-duty 2500 carried a maximum payload of 2,848 pounds and towed up to 10,000 pounds. A rear-wheel drive extended cab light-duty 2500 hauled a max payload of 2,657 pounds and had a maximum towing capacity of 10,000 pounds.
