The 2001 Sierra C-Series, sporting a freshened front end and due this fall, cuts across traditional load-rating and trim-level classifications to combine a comprehensive selection of powertrain, chassis, exterior, and interior features in one fully-equipped, extended-cab, half-ton pickup. Components and systems that constitute this new GMC product are for the most part without precedent in the pickup truck world.
The "C" designation signals a third generation for GMC's full-size pickups following introduction of the Sierra badge in 1988 and the line's complete reengineering in the 1999 model year.
"GMC has been a truck innovator for nearly 100 years and the C-Series carries on that tradition of innovation with a totally exclusive Sierra entry," said Jim Kornas, Sierra Brand Manager. "Intriguing new technologies and an exclusive level of on-road control and performance give this vehicle an unprecedented driver character in the ½-ton extended cab full size pickup segment."
This driving character is neatly packaged into a concept GMC has coined, "Performance Biased Driveline." So embedded is this concept of a full-size pickup with the ultimate in on-road performance and control that the C-Series wheel center cap have the words, "Performance Biased Driveline," engraved on them.
All Wheel Drive
Pickup trucks have historically depended on four-wheel drive to dig through deep mud, drifted snow, or severe off-road terrain. Building on this experience, the C-Series uses the superior traction provided by four driving wheels to yield a completely different benefit--the best on-road, wet- or dry-pavement handling performance ever engineered into a full-size pickup. German luxury-car makers Audi, BMW, Mercedes, and Porsche have long depended on all-wheel-drive for their top performers, but this is the first introduction of such advanced technology in a full-size pickup truck.
Driving all four wheels provides reserve traction, giving the C-Series superior cornering and accelerating capabilities. Full-time, all-wheel drive is provided by a special transfer case mounted directly to a heavy-duty 4L60-E automatic transmission.
The beauty of the C-Series all-wheel-drive system is that it automatically compensates for varying traction conditions on the front and rear axle to route drive torque to those wheels with the grip capable of propelling the vehicle forward. This system is permanently engaged, always active, and so progressive that its operation requires no driver activation. There are no transfer-case levers to throw or buttons to press.
No extra equipment is necessary to handle towing assignments up to a towed load of 8800 pounds (3.99 tons) with a GCWR of 14,000 pounds (6.35 tons) with the Z82 heavy duty trailering package. The package includes a 12,000-pound (5.44 tons) weight-distributing platform trailer hitch, a seven-pin trailer harness connector, transmission temperature gauge and a "plug and go" trailer brake controller jumper harness.
Brand manager Jim Kornas characterizes the Sierra C-Series as "an international class vehicle, created to be capable yet sophisticated in its on-road mannerisms." He adds, "This is not your traditional full-size pickup. No one has ventured quite this far in the realm of performance, control and all-around refinement in the truck arena.
OnStar Communications is provided as standard Sierra C-Series equipment. Three control buttons are positioned at the bottom of the inside rear-view mirror to command a link to the 24-hour OnStar center where a driver can obtain a variety of safety and security services. Onboard vehicle electronics and Global Positioning System satellite technology are the basis for this sophisticated communications link.
Front bucket seats have integrated passenger restraints, electrically heated bottom cushions and backrests, and articulating headrests. Driver and passenger power adjustments include 6-way position, backrest recline, lumbar support, and backrest bolsters. A memory system moves the driver's seat to one of two different settings on command. The front passenger seat has a child seat top tether anchor and a lower attachment point for snap-in safety seats. The roomy three-passenger rear seat folds upward to clear the way for interior cargo. It too is fitted with tether anchors and snap-in child seat attachments. Striking tone-on-tone leather with a sophisticated sew pattern covers all seating surfaces.
The C-Series Delco AM/FM stereo is augmented by a six-disc CD changer mounted in an extension of the center console. Pressing one button permits loading up to six CDs in rapid sequence.
