1999 GMC Sierra...Continued

The GMC Sierra trucks have a full range of new gasoline V8 engines and diesels, long and short bodies and beds, plus all transmission and drive configurations. GM has reworked the interior, especially the seats and controls. The true 4-door crew cab are not available yet on the new models, but will be adapted in the near future. GMC is taking a page from Fordâs book in phasing in production of the new trucks while keeping the â98 models in the pipeline.

Despite introducing third door, GM has not picked up on the fourth door that its competitors now have, but have shoulder harness built into the seats which is a wonderful benefit for comfort and convenience.

GMâs third door on the extended cab trucks aids in getting people and supplies out of the area behind the front seats, but has an additional benefit. People with limited mobility, especially those in wheel chairs find them highly adaptable for their needs, and much more sporty than the vans to which they were previously relegated. Most companies have special pricing plans for qualified buyers with physical challenges.

Their most outstanding feature for most truck owners is the Vortec technology in the engines. The result is the most powerful family per displacement in the industry. Vortec technology is no single area of improvement, but careful attention to every aspect of the engine. These new engines are smaller in displacement than their predecessors, but have more power and better fuel economy.

They are based on the layout that has made the Corvette engine such a success, but are built using cast iron for working durability. The two smaller engines have aluminum cylinder heads, and as soon as the fleet owners get convinced of the maintainability of the lighter metal, so will the 6.0 version.
