1999 GMC C1500 Review

Pickup truck durability with sporty power and guts.

Reviewed by Automotive on


The GMC light duty pickup has been a classic workhorse for quite some time. The market for pickup trucks is very competitive, so GM has infused its line of trucks with more horsepower and torque, as a means to lure younger buyers away from the Dodge Ram and Ford F-Series. The 1999 C1500 has a tough looking exterior with the power of a sport car.

Its new update has given the Sierra a larger cab, longer wheelbase, and multiple mechanical enhancements. The GMC C1500 is available with an extended or regular cab size with a short or long truck bed.

What's New

The 1999 GMC C1500 gets a completely new look. While the truck has evolved, the redesign gives it a much more spacious interior, a stronger and more rigid body frame, and a new line of five powerful engines.


The 1999 GMC C1500 doesn't have any major exterior changes. The wheelbases are slightly longer than previous incarnations, with the regular cab short bed truck riding a 119-inch wheelbase, while the regular cab long bed truck has a wheelbase of 133 inches. The extended cab short bed rides a wheelbase of 143.5 inches, while the extended cab long bed has a 157.5-inch wheelbase.

The 1999 GMC C1500 trucks now have a hydroformed frame that is comprised of three separate sections. Structural enhancements have eliminated rattles and squeaks, while also making the vehicle much safer than it was in the past. The SLE and SLT extended cab trims now have an optional side access door panel, making the truck more family friendly. While both Dodge and Ford have introduced four door trucks for the 1999 model year, the Sierra will most likely not get a four- door truck until the 2000 model year.


The 1999 GMC C1500 can seat anywhere from two to six people, depending on the style and whether or not optional seats are chosen. The C1500 seats are incredibly comfortable with great lumbar and lateral support. Seating can come with either cloth or leather upholstery. Leather is likely the preferred choice for anyone seeking some luxury with a pickup truck; however, the cloth seats are much cooler in incredibly hot weather. The front seats have the seatbelts built into them. This simplifies getting into the backseat since there are no hanging belts to duck under.

The 1999 GMC C1500’s instrument panel has been thoroughly upgraded with large print gauges, new heating and cooling controls, and three new power outlets. Large cup holders extend out from the center. Some buyers have pointed out a distinct gap between the instrument panel’s edging and the windshield pillar. Buyers that want to be pampered will appreciate the new optional heated seats. Standard features include tilt steering, front cup holders, an AM/FM radio, a tachometer, oil pressure gauge, and a front center armrest with storage. Air-conditioning is standard for the SLE and SLT trims and an option for the SL.

Performance & Handling

The 1999 GMC C1500 benefits from Vortec technology, whether it is the base V-6 engine or the all powerful V-8 engine. Each engine produces great power and torque. The 5.3-liter engine, cranking out 270-hp, is the best of the pack. The C1500 is quick revving just like a powerful sports car, while also staying quiet with minimum vibration. Not only is this vehicle durable enough to withstand construction sites, towing and hauls, but this pickup truck can breeze in and out of traffic on the highway as well.


The 1999 GMC C1500 comes standard with four-wheel anti-lock brakes, daytime running lights, and driver and passenger front airbags. There are no NHTSA crash test results available at this time.

EPA Fuel Economy

GMC 1500 4.8-liter V-8: 16/21 mpg city/highway
