In 1991 Chevrolet produced four main pickup styles: the smaller S-10, the regular-duty C/K 1500 and two heavy-duty models, the C/K 2500 and 3500. No major changes were present for this year as Chevy stuck with what was working for it. Primarily used as farm or ranch vehicles or work trucks, you can still see these models on the road today, still at work.
1991 Chevy S-10 Pickup
This smaller pickup featured two engine options, the 2.5-liter, 105-hp I-4 or the 4.3-liter, 160-hp V-6 engine. The first produced 105 hp with 135 lb-ft of torque and the second was capable of reaching 160 hp with 235 lb-ft of torque. It came in either a regular cab or extended cab and buyers could select between the short bed or long bed options.
The gas mileage rating for these pickups was quite good ranging from 21 to 33 mpg. The maximum amount of seating for regular cabs was three adults, while the extended cab offered seating for four adults.
Airbags were not offered on this model but ABS brakes were standard across the line.
1991 Chevy C/K 1500 Pickup
The C/K 1500 model was available with four engines: a 6.2-liter diesel V8, a 210-horsepower 5.7-liter V8, a 175-horsepower 5.0-liter V8 or a 160-horsepower 4.3-liter V6. A four-speed automatic transmission with overdrive was standard across all models. This pickup was also available in either a standard or extended cab, with two- or four-wheel drive, and the option of a long or short box was also offered.
The regular cabs were able to hold three adults, while up to eight could be seated in the extended cab, long box version of this pickup. Gas mileage was largely dependent on the size of the pickup, despite the fact that every model had the same engine.
1991 Chevy C/K 2500 Pickup
The 2500 heavy-duty pickup offered a choice of two gas engines, the 4.3-liter, 160-hp V-6 or the 4.3-liter, 155-hp V-6. On diesel models, the 6.2-liter, 150-hp V-8 was standard. A four-speed automatic transmission with overdrive was standard on all models except the extended cab long box model, which came with a four-speed manual transmission.
Airbags were not provided in any models but ABS brakes were once again standard in these models.
1991 Chevy C/K 3500 Pickup
Two different engines were made available for the largest size pickup in 1991. The 5.7-liter, 255-hp V-8 or the 7.4-liter, 290-hp V-8. A five-speed manual transmission with overdrive was offered standard on all models, but a four-speed automatic transmission was an available option. These pickups were only available in two-wheel drive and came with either the 5.7L engine in a regular or extended cab or the 7.4L version with either a standard or crew cab with a long box.
