GMC Sierra Pro Plus Concept Truck

By: Michael LevineLast Edited: 11-05-01 00:00

GMC continues to refine its series of Sierra Professional trucks, which first appeared at SEMA in 1999, with the debut of the all new Sierra Pro Plus concept pickup.

The Sierra Professional, given the greenlight for production as a 2002 option package on the GMC Sierra, forms the foundation for the Sierra Pro Plus concept and shares much in common with this truck. Many of its components are either available today or seem destined for production in the near future.

We spoke with GMC Sierra Assistant Brand Manager Lorraine Babiar about this latest "Professional Grade" iteration. Babiar began work with her team on the Sierra Pro Plus back in January of this year.

Incorporating many of the best ideas to date, the Pro Plus most notably introduces quarter side storage, a removable split rear seat and Magna Steyr supercharger.

Quarter side storage is very similar to a product we came across at SEMA two years ago called Hide-N-Side. The Sierra's rear quarter panels have been transformed into a very convenient storage area complete with customizable racks and bins. Created out of the same SRIM material used in the Chevrolet Silverado's composite bed, the Sierra Pro's quarter side storage panels easily fold down and are locked in place when the tailgate is up. This is also a feature that will be showing up in another GMC concept, the Terra4, expected to debut in January at Detroit's North American International Auto Show. Given these two massive hints, we expect to see quarter side storage offered as an option in production Sierra's by 2005.

The 60/40 removable split bench seat in the rear of the cab is also another feature that will likely find its way to production in the not too distant future. Owners can remove the "40" portion during the day for work related purposes, substituting the seat for more rack space to hang toolboxes from. At night the seat can be quickly reinstalled to accomodate the entire family. Under the rear seating is the same large storage bin currently offered in the production Sierra Professional.

Magna Steyr has supplied the the supercharger under the Pro Plus's hood. With this blower the Vortec 6600, already a powerful engine, gains an additional 20% bump in horsepower to 328 hp and 23% more torque for a total of 356 ft-lbs. GM's Service Parts Organization is working closely with Magna Steyr to potentially offer this supercharger as a dealer installed option. Magna Steyr already does a similar package for Toyota's Tacoma compact pickup and will soon add a dealer installed supercharger for the Tundra.

One other item likely to find its way into production on a GMC truck is the Magna reconfigurable tailgate module that quickly changes from a bed extender to cargo loading ramps. This same system was featured last year at SEMA on GMC's Sonoma Recon concept.

Other items of note sure to be enjoyed by contractors and others who might purchase this truck are the Grammer Air Ride front driver and passenger seats. These seats offer plenty of comfort and even include a massage lumbar system for winding down after a tough day at work. A Panasonic Toughbook laptop pops out of the driver's side rear door panel. The perfect computer built to take a beating at the construction site.
