What's New

The 1999 GMC Sierra makes its debut this year and marks a significant redesign in GM’s lineup of pickup trucks. The automaker removed the decades-old C/K Series design and replaced it with a more modern design. The truck receives a number of enhancements in its structure, braking, engine power, and interior.

Exterior

The redesigned exterior of the 1999 GMC Sierra is not exactly revolutionary, but it does signify a big change from the outdated C/K design. The Sierra uses a new three-piece frame construction. Each piece of the frame has its own unique function with one protecting the engine and suspension and another accommodating and supporting the trailer hitches. As a result, the frame absorbs 35 percent more energy than its predecessor did: reduces vibrations and improves the safety of the pickup.

Interior

The 1999 GMC Sierra's new arrangement and layout of the gauges and controls are the best in its class in terms of design, location, and feel. The company also offers an odometer with an engine-hour meter. The front seats for the 1999 GMC Sierra offer lots of headroom and legroom, and it's supportive as well. The integrated seatbelts comfortably move with the seats, so there is no problem in that department. However, some drivers may find themselves squeezing between the seat and door panel to reach certain controls.

The 1999 GMC Sierra and its Chevrolet sibling offer more headroom and legroom in its rear bench than its Ford and Dodge rivals do. Moreover, the bench itself is as comfortable as the bench of a sedan with its reclined backrest and contoured cushion. The doors open very wide on the extended cab models, making entry and exit very easy.

Performance & Handling

The 1999 GMC Sierra is available with a number of engine options. The base engine is a 4.3-liter V-6 engine that delivers 200 horsepower and 260 lb-ft of torque. Two V-8 engines are available as options. One is a 4.8-liter engine that delivers 255 horsepower and 285 lb-ft of torque, while the other is a 5.3-liter engine that delivers 270 horsepower and 315 lb-ft of torque. There is also an available six-liter V-8 engine with 300 horsepower and 360 lb-ft of torque. All engines except for the last one are available with either a manual or an automatic transmission. The six-liter engine is only available with automatic transmission.

The 1999 GMC Sierra expectedly outperforms its predecessors, but the difference is not that dramatic. The new V-8 engines, based on a Chevrolet Corvette engine, are smooth and definitely powerful with a little less torque than previous generations, so the Sierra has almost the same throttle response and acceleration as its predecessors did. The V-6 engine is quite a smooth engine too, but it clearly struggles to deliver enough power for pulling heavy loads or up steep slopes. For an all-round experience, the 5.3-liter engine is perfect, even though it trails behind the torque offered by Ford’s 5.4-liter engine by just a bit.

Safety

The 1999 GMC Sierra received three out five stars in terms of driver safety and four stars in terms of passenger safety during frontal impact tests conducted by the NHTSA.
