GMC Trucks > 2000 GMC Sierra

Summary

Two models of Sierra pickup are offered in the 2000 model year, Sierra Classic and Sierra. The Sierra Classic continues the previous generation body style and mechanicals and the Sierra continues the vast improvements made to the recently redesigned GMC Sierra.

Details

Set to go into production in November, the GMC will sport four doors on the extended cab models. The fourth door will put the GMC in the same league as the current Dodge Ram and Ford F-Series trucks in terms of passenger access and loading capability. The Sierra will have the largest extended cab rear door openings in the full-size pickup truck segment. Expect the optional fourth door too add 56 extra pounds of weight of the vehicle over the three door model.
The fourth door's extra weight should be offset by a new plastic bed option which saves 50 pounds, but this is not set to be offered until the 2001 model year on the Sierra and its twin the Chevrolet Silverado.

The standard Sierra seating continues to be a 40/20/40 bench for three across seating. The driver and passenger seats feature adjustable head restraints, forward, and upward tilt adjusters. Seat belts are mounted on the outboard position of bench seats and on bucket seats. A standard driver Message Center reports up to 18 vital vehicle functions and can alert the driver of impending or potential service conditions. Dual airbags are standard.

Engine improvements will expand on the capabilities of the Vortec lineup, including the Vortec 4800 (standard on all 1500 series extended cab models), 5300 and 6000. GMC claims the Vortec V8s are the most fuel efficient in their class. The Vortec 4800 and 5300 will use a redesigned camshaft that adds 15 more horsepower, gets better fuel economy, and adds 10 more ft-lb of torque to the 5300.

  • Vortec 4800 - 270 hp@5200 rpm and 290 ft-LB of torque@4000 rpm
  • Vortec 5300 - 285 hp@5200 rpm and 325 ft-LB of torque@4000 rpm
  • Vortec 6000 - 300 hp@4800 rpm and 355 ft-LB of torque@4000 rpm

The 4300 Vortec V6 (standard on all 1500 series regular cab models) has been upgraded with new roller rocker arms, a new roller timing chain, and powdered metal sprocket for improved quality, reliability, durability, and a quieter engine. The 4300 also adds long life platinum tipped spark plugs good for 100,000 miles before the first tune-up; extended life coolant, good for up to five years or 150,000 miles, and a new oil level sensor that alerts the driver to low oil conditions.

The improvements to the engines have also resulted in better trailer towing ratings. The torque curves of the engines allow for strong, high, flat curves similar to competitors trucks.

In the 1999 models, trailer ratings equaled the GCWR - vehicle weight where vehicle weight is EPA curb weight plus the driver and one passenger and the rating is rounded down to the nearest 500 pounds. In the 2000 models, trailer ratings equal the GCWR - vehicle weight where vehicle weight is base curb

weight plus the driver and the rating is rounded down to the nearest 100 pounds. The new rating methodology more accurately reflects the full extent of the Sierra's towing capabilities - which have increased by 600 to 900 pounds.
  • The Sierra 1500 2 wheel drive model with the Vortec 4800 can tow 800 pounds more than last year's model for a total of 7800 pounds. This is for models with the 3.73 axle ratio and trailer towing package.
  • The Sierra 1500 2 wheel drive model with the Vortec 5300 can tow 600 pounds more that last year's model for a total of 8800 pounds. This is also for the 3.73 axle ratio models
  • The Sierra 2500 2 wheel drive model with the Vortec 6000 can tow 700 pounds more than last year's model for a total of 11,200 pounds. This is for models with the 4.10 axle rating and trailering package
