If you were working on one of the road projects along the California Coast and you saw my wife and I rolling through the work zone in a shiny new GMC Sierra towing an iconic Airstream travel trailer I want you to know I was working. I know how it can be working long hours in the heat when people are clearly on vacation all around you, so I thought you’d feel better about it if you knew others were right there working with you.

I can understand that you thought a vacation camping trip was underway  when you saw the GMC/Airstream combination and I don’t blame you, because appearances can be deceiving. I was working hard testing the latest in GMC pickup offerings and of particular interest was the towing capability. I would have asked to borrow a trailer with a skid steer or other piece of equipment on it, but I knew you had them busy fulfilling contractual obligations.

So the brand new custom Airstream would have to fill in for tow testing. It also helped my company save some lodging money because we were able to camp a couple of nights while we tested the new trucks. The fact that our Airstream 2 Go trailer featured a contemporary interior designed by award-winning San Francisco architect and designer Christopher C. Deam did not interfere at all with our truck test. Five star linens, plush towels, Ultraleather fabrics, flat screen LED television and powered awning – all standard in the Airstream 2 Go units made it a stretch to call it camping, because, after all, it was work.

We started our SoCal adventure, that is business trip, by flying into LA International where we picked up our pickup and headed north along the coast to an airstrip where GMC had set up a towing school. Not all of the journalist invited had towing experience so our old friend Robert Krouse, GM’s Lead Trailering Engineer, took us through the basics.

GMC gets serious about towing instruction for the introduction of the new Sierra.GMC gets serious about towing instruction for the introduction of the new Sierra.

What was a Towing 101 for some folks was for me an opportunity to put the pickup and trailer combination through some maneuvers on a closed course that you would not want to try on the highway unless it was an emergency.

The first thing I noticed was the integrated trailer brake controller. The first thing my wife noticed was the IntelliLink connection so she could download a new book on her Kindle.

“Better be a work related book,” I observed.

“Whatever,” was her only reply as she kicked  off her beach sandals and took another sip of her smoothie.

Focus Larry, you’re working here…

So the integrated trailer brake controller with easy-to-reach controls high and left on the dash would be easy to adjust with clearly marked buttons. It would also be easy to give the trailer brakes some manual input with the slider within easy reach.

System information is displayed in the Driver Information Center on the instrument cluster.

 

The Trailer Brake Controller allows owners to quickly modify trailer braking force based on the weight of a trailer. For example, a driver delivering heavy building supplies could adjust the controller to lower trailer gain for an empty trailer on the return trip, minimizing the chance of trailer wheel lock-up.

We had experienced the trailer brake controller before on the GM HDs, which influenced other tow vehicle features of the new 1500.

“Trailering is a fundamental capability that customers invest in and depend on when they purchase a truck,” said Tony DiSalle, vice president of GMC Marketing. “The 2014 Sierra backs up its unmatched capability with a host of ingenious driver aids.”

Classroom or test track? Towing just got a lot easier with the new Sierra.Classroom or test track? Towing just got a lot easier with the new Sierra.

Before the 2014 Sierra is even in motion, systems are monitoring conditions and preparing the truck to perform. On any grade of about 5 percent or higher, Hill Start Assist automatically engages the Sierra’s brakes for 1.5 seconds or until the gas pedal is pressed. This keeps the truck from rolling rearward and helps in trailering situations like climbing a boat launch.

Tow/Haul mode, activated by a button on the shift lever, modifies the standard six-speed transmission’s shift mapping to take full advantage of the Sierra’s powerful new EcoTec3 engines. Under acceleration, shift points are higher for more power, while downshifts are initiated earlier to promote engine braking, reducing wear on the Sierra’s disc brakes.

With Tow/Haul mode engaged, Sierra’s Trailer Grade Braking is activated when the driver lightly applies the brakes. This feature initiates downshifts to assist with braking on long downgrades. In addition to slowing the vehicle more efficiently, Auto Grade Braking can reduce brake rotor temperatures by 100 degrees Celsius during a braking event.

Airstream 2 Go provided our trailers and our lodging for the event.Airstream 2 Go provided our trailers and our lodging for the event.

For drivers who prefer full control over their truck’s shifting, improved TapShift controls on the shift lever are backed by a patent-pending shift algorithm that improves shift response time by up to 60 percent compared to previous systems. When the TapShift controls are in use, Sierra’s Trailer Grade Braking is deactivated because the driver is manually controlling gearshifts.

Trailer Sway Control works with the Sierra’s standard StabiliTrak to provide the driver with additional assistance when towing a trailer. When it senses trailer sway, it intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. It also uses the electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck.

The 2014 Sierra’s optional Max Trailering Package allows trailering up to a class-leading 12,000 pounds with the optional 6.2L EcoTec3 V-8 engine. The Max Trailering Package is available on 2WD and 4WD V-8 crew cab and double cab models and includes:

•             Trailering package with seven-pin and four-pin connector

•             Enhanced cooling

•             Automatic locking rear differential

•             Heavy-duty 9.75-inch rear axle with 3.73 ratio

•             Increased-capacity rear leaf springs

•             Revised shock tuning for increased contro

•             Integrated trailer brake controller.

Sierra’s 5.3L EcoTec3 V-8 offers maximum trailering of 11,500 pounds, more than any  competitor. Sierra’s 4.3L EcoTec3 V-6 can trailer up to 7,200 pounds, 500 pounds more than a Ford F-150 3.7L pickup and 700 pounds more than a Ram 1500 3.6L.

New looks include  projector headlights with LED highlights.New looks include projector headlights with LED highlights.

An all new aluminum hood with a bold profile as tall as the HD models,  a stiffer fully boxed frame, sophisticated engine braking in tow haul mode and projector beam headlamps with LED lighting give the truck a new look with plenty of added capability.

Style cues abound in the interior as well with soft touch surfaces and contrasting stitching, but style also meets substance inside the 2014 Sierra:

  • Exceptional storage space in the center console is big enough to store hanging file folders, laptops and much more in the bucket-seat models.
  • Dual-density seat foam that holds its shape longer and keeps you comfortable
  • Larger controls that are easy to reach and read
  • USB ports and 12V charging outlets
  • Available 110V power outlet
  • Improved rear-seat legroom on crew cab models
  • Locking under-seat storage on SLE models with front bench seating

A number of design features contribute the quiet ride:

  • Triple door seals that block outside noise
  • Shear body mounts that improve ride by tuning out vibrations
  • Improved aerodynamics which reduce wind noise
  • A valved exhaust system that reduces engine noise
  • Hydraulic powertrain and body mounts that reduce vibrations

Of course, all of these refinements seem to take on new meaning in GMC’s well known Denali package, which gives the fall with an available 6.2L EcoTec3 V-8 that will produce an estimated 420 horsepower and 450 lb-ft of torque, the most power and torque of any light duty truck engine.

Final SAE-rated power and torque numbers will be available later this year. Now entering its third generation, the Sierra Denali is the most luxurious and technologically advanced GMC half-ton pickup.

Sierra’s 6.2L V-8 will also be available for Sierra SLT models this fall. With this engine, the Sierra is expected to have a class-leading maximum trailering capacity of 12,000 pounds. Like every 2014 Sierra, it offers more power and higher expected efficiency than its predecessor thanks to a trio of technologies including direct injection, active fuel management and variable valve timing.

Design cues for the 2014 Sierra Denali follow the formula that attracted two-in-10 GMC buyers to Denali vehicles last year. On the exterior, the truck has a signature Denali chrome grille, unique 20-inch chrome wheels, unique interior decorative trim, a polished stainless steel exhaust outlet and body-color front and rear bumpers. Denali-specific interior details include script on the bright door sills and embossed into the front seats and real aluminum trim.

Sierra Denali’s high-tech interior also features an exclusive eight-inch Customizable Driver Display that can show relevant settings, audio and navigation information in the instrument panel. Sierra Denali’s standard eight-inch Color Touch navigation radio with Intellilink, located above the center console, serves as the main hub for Bluetooth-connected phones and portable devices connected through five standard USB ports.

Other features standard on Sierra Denali include projector-style headlamps with LED signature daytime running lights, a Bose audio system, heated and cooled leather front bucket seats, a heated steering wheel, front and rear park assist and a power sliding rear window with defogger.

“The 2014 Sierra Denali has a combination of performance, capability and luxury that no other pickup can match,” said Tony DiSalle, vice president of GMC Marketing. “It leaves no boxes unchecked for those owners looking for the ultimate expression of ‘Professional Grade.’”

A 5.3L EcoTec3 V-8 is standard for the 2014 Sierra Denali. It produces 355 horsepower and offers better EPA-estimated fuel economy (23 mpg highway on 2WD models) than any V-8 or turbocharged V-6 pickup on the market.

Sierra Denali will be available with two option packages, including a Z71 Off-Road Package (4WD only) with monotube Rancho shocks, Hill Descent Control and transfer case shield, and a Driver Alert Package that includes Lane Departure Warning, Forward Collision Alert and patented Safety Alert Seat Technology.

Standalone options include the 6.2L EcoTec3 V-8, a sunroof and Rear Seat Entertainment.

TEST RESULTS

Our Southern California test of the 2014 GMC Sierra found the truck to be as much at home on the beach as in the restaurant district of Santa Barbara. Our towing test found the Sierra on par with the best trailering light truck setups on the market with clear design attention given to towing, with great results.

High mobile office marks were earned for multiple power source options, internet hotspot capabilities and attention to detail in interior storage.

Overall, the 2014 GMC Sierra will make a great work truck for light duty uses and for those who also use their trucks for play – well, you’ll have to ask someone who has vacationed in one. We wouldn’t know anything about such activities because we are out here working hard to keep you informed about the best ProPickups available.
