GMC Sierra 3500 Wins ‘Heavy-Duty Hurt Locker’ at Pickuptrucks.com

Pickuptrucks.com has once again held a competition pitting the Big 3 automakers against eachother in a test to see who comes out on top. This particular test, aptly named ‘Heavy Duty Hurt Locker’ had one-ton dual rear wheel pickups complete a 2,200 mile journey across 4 states through 2 of the most gruelling mountain climbs in North America. The trucks pulled gooseneck trailers weighing nearly 10 tons through the journey (meaning a commercial drivers license was required!) and were evaluated on their fuel economy, power, acceleration and braking. Trucks were also measured on closed courses, going full throttle with and without trailers, to measure their performance at 100% power capability.

The trucks all fared well and had their own pro’s and con’s in each test, but in the end the award was given to the GMC Sierra 3500, with the writers stating:

The GMC Sierra 3500 is our choice for the Best Overall Heavy-Duty Truck in the Hurt Locker test. Its performance continues to affirm what we’ve seen from previous 2011-12 GM HD pickups. Their chassis and on-road performance should be in the crosshairs of Ram and Ford.

The GMC Sierra led with best-in-class performance, with wins in almost every test we put the trucks through.

The Sierra was the most comfortable rig over our long days. It was also the quickest for the driver to get comfortable with the trailer and load.

So there you have it folks – head over to pickuptrucks.com for the full (and extremely in-depth) rundown. Come in and see us if you’d like to give the Sierra 3500 a test of your own!


The Biggest, Baddest Davis Customs Sierra

Well folks, here we have another Davis Customs creation to unveil – and this one is, in my opinion, the best one yet. We decided to go with a big, mean offroading machine this time around, and have a look for yourself at what the end result was! We started with a Fire Red 2011 GMC Sierra SLE 1500 Crew Cab 4×4, added a 2″ lift to get over that really rough terrain, and flat black 20″ wheels wrapped in 305(!!)/50/R20 Cooper Zeon LTZ rubber – that combination gives the truck an aggressive stance that shows it means business! And to get all that meat around in good time, we selected a truck with the optional 6.2L V8, which cranks out 403 HP!

But no, we didn’t stop there. When you’re riding in a truck like this, you’re going to want to be comfortable, so we ordered custom Katzkin black leather interior with red stitching and seat warmers. Let me tell you, this leather is unbelievable! And the red stitching really sets off the whole red/flat black look the truck has. Take a look at the pictures, and come down to see the truck in person, but hurry in cuz it won’t last!




Diesel Exhaust Fluid and the 2011 Duramax Diesel


The enhanced, legendary Duramax 6.6L Turbo Diesel is the most powerful Duramax ever built – generating more horsepower and torque than ever before. This proven powerplant gets the job done while being friendlier to the environment.

The improved Duramax uses the latest emission control technology, reducing Nitrogen Oxide (NOx) emissions by a whopping 63% when compared to the 2010 model. GM engineers determined the best way to accomplish this remarkable reduction of diesel emissions was to employ a Selective Catalytic Reduction (SCR) system that uses Diesel Exhaust Fluid (DEF).

Selective Catalytic Reduction (SCR)

The SCR system is an after-treatment system, since it treats the vehicle’s exhaust after combustion. Here’s how it works:

  1. A fine mist of DEF is injected into the exhaust while the engine is running
  2. The heat from the exhaust converts DEF into ammonia
  3. When the ammonia, mixed with exhaust gases, reaches the SCR catalyst, the NOx emissions are broken down
  4. The Diesel Particulate Filter (DPF) then captures soot to incinerate it during regeneration cycles.
  5. Water vapor, nitrogen and reduced emissions exit the exhaust system.

What is DEF?

Diesel Exhaust Fluid is a non-flammable fluid comprised of 33% ammonia-based urea and 67% purified water. DEF is used with diesel engine exhaust systems to reduce the amount of emissions produced by turning Nitrogen Oxide (NOx) into nitrogen and water vapor. DEF technology has a proven track record since it has been used in Europe for years.

Driving Range Between DEF Tank Refills

The SCR system uses DEF at a rate of about 1 to 1.25% of the vehicles diesel fuel usage. A full tank of DEF provides a driving range of about 8,000 km. Since DEF is directly related to fuel consumption, range will vary depending on driving conditions

Refilling Your DEF Tank

DEF is stored in a 5.3 gallon (approx 20L) tank located under the passenger side of the cab. The DEF tank fill point is conveniently located under the hood, along with other fluids that require periodic maintenance. It’s easly identified with a blue cap. DO NOT OVER FILL THE DEF TANK

Storing DEF

DEF shelf life is typically at least one year, depending on the storage temperature. It is best stored out of direct sunlight at room temperature. Small DEF spills can be cleaned up by absorbing it with dry earth, sand, or other non-combustible material and scooping it into a container for disposal. While DEF is not listed as a hazardous waste by the federal government, please use proper disposabl methods. Do not empty into drains; dispose of this material and its container in accordance with all applicable local and national regulations.

Electronic Onboard Warning System

There is no guessing involved when it comes to maintaining a correct DEF level with this system. An electronica onboard warning system provides you with numerous warnings in the Driver Information Center to help you maintain adequate DEF levels, alert you if the DEF quality is poor or if there are concerns with the system. See your Duramax owner’s manual supplement for a complete description of the electronic onboard warning system and its warning messages.

Maintaining DEF Fluid Levels

The electronic onboard warning system will provide a message alerting the driver when the DEF level is around 1,500 km remaining range. Additional messages that must be acknowledged alert the driver at the 500 km, LOW, and 0 km fluid ranges as the DEF tank gadually empties. The fluid level in the DEF tank must be maintained for the vehicle to run correctly. If the DEF tank is allowed to run empty, the system will alert the driver. If fluid is not added at the next vehicle start, the vehicle speed will be limited to approx. 88 km/hr and ultimately to 7 km/hr in accordance with federal requirements.

Adding DEF to an Empty or Low Tank

Always add at least 4 L to release the vehicle from any speed limitation. Once the system is refilled, the system resets itself and a service visit is not required. It may take up to 30 secondsin park or several km of driving to update the DEF level warning.

Will DEF Freeze?

DEF freezes at approximately -11 degrees celsius, so the tank and DEF system are designed to freeze in cold climates. If DEF is frozen, the vehicle will still start as it always has. There is a second tank inside the DEF tank that is heated in 270-minute intervals while the engine is running, to ensure DEF fluid is thawed. This cycle was originally 90 minutes and that produced some of the freezing problems with trucks located in cold climates for extended periods of time, but the new program extends the cycle to 270-minutes to ensure enough DEF is circulated to keep the truck running at optimal standards. Residual heat from this internal tank helps to heat and thaw the remaining DEF in the larger tank. Do not overfill your DEF tank, as freezing will cause the fluid to expand and in turn could damage the tank.

More Pictures of the All Terrain HD

Oh how I wish I could be in Detroit for the North American International Auto Show right now. I’m sure that sentiment is shared by more than a few people around here, as it looks like all the manufacturers are coming through with exciting new products at the show.

Last week we had a post about the Sierra HD All-Terrain Concept, and GM made good on its promise to bring the concept to NAIAS.  Unfortunately I can’t be there to see this beauty in person, but the guys at autoblog.com took a few pictures up close, and I’ll share them here for your viewing pleasure.


GMC Sierra All-Terrain HD Concept


Due to be released at the Detroit International Auto Show from GM: The GMC All-Terrain HD concept. You may be familiar with the half ton Sierra All-Terrain (different wheels, grille, interior than a standard Sierra) but the HD goes a little more off the map…. Powered by the 6.6L Duramax diesel, the truck also has an extra 3 inches of ground clearance, is 4 inches wider, and rides on 20-inch wheels wrapped in 35-inch offroad tires with Fox off-road shocks (same as used on the Ford Raptor.)

Inside, the concept comes with Denali-spec interior and satin metal finishes – much like it’s half ton counterpart, but also has the upcoming next generation 80 gB hard drive that we’ll be seeing across the full GM line in the next few years. Being a concept there are no plans to actually produce the truck… yet… but if it were to be produced you would likely see it come from a third party firm as opposed to rolling off the GM production line looking like that.

Will be excited to see the concept at the Detroit show, and maybe find a few more details about possible production of the truck, but for now enjoy the pictures.

Sierra HD Concept Coming To NAIAS In January


Pickuptrucks.com is reporting that  GMC is going to unveil a preview of its next generation Sierra HD at the North American International Auto Show in Detroit in January. For the 2011 model, GM introduced an all new chassis and an updated Duramax diesel V8 engine, but the body style has remained the same since its mid-2007 model year launch. More news to come when GM officially announces the concept, we’re looking forward to it!
